which fuels can an otto engine run on

Which fuels can an Otto engine run on? In general, it is obtained from direct distillation naphtha, which is the lightest liquid fraction of petroleum (except for gases). Typically, the drop-off is in the same range as the reduction in peak engine power (3-5 percent). As for 4-stroke engines, they run on gasoline without any oil mixed in and the piston goes up and down two times for every combustion cycle, hence its called a 4-stroke. However, 4-stroke engines require valves for both the intake and exhaust that must operate with high precision, making this engine format more . Hydrogen containing gases can be found as by-product from steel ( furnace gas) or chemical process, or . Among the two methods of laminating fuel, the most widely used is fueled by carburization. This is in contrast to igniting the fuel-air mixture with a spark plug as in the Otto cycle (four-stroke/petrol) engine. The first automotive V8 engine to reach production was the 19141935 Cadillac L-Head engine introduced in the Type 51. Otto fuel II was invented by Otto Reitlinger in 1963 (although tests with the substance had taken place before, for example in 1960); it is named after Reitlinger and for being the second . Otto and Cie succeeded in creating a successful atmospheric engine that same year. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); 2023 FAQS Clear - All Rights Reserved The first version used a frame to stabilize the rack. It was a low-RPM machine, and only fired every other stroke due to the Otto cycle, also designed by Otto. In this example, let assume an Otto cycle with a compression ratio of CR = 9 : 1. In petrol engines, the power developed is low due to the compression ratio, whereas in diesel engines, the power is more. The gas (fuel-air mixture) expands adiabatically from state 3 to state 4. Sadly, even with regular car maintenance such as a tune-up or an oil change, todays gasoline engines are only around 30 to 35 percent efficient, which means roughly 65 cents out of every dollar you spend on gas goes to waste. What Is the Fuel That an Otto Engine Uses? But that is not enough for working machines. The four stroke Diesel engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning a crankshaft. The main. The Otto engine was a large stationary single-cylinder internal combustion four-stroke engine designed by the German Nicolaus Otto. During WWII Otto engines were run on more than 62 different fuels, such as wood gas, coal gas, propane, hydrogen, benzene, and many more. Diesel combustion. For instance, an electric generator converts mechanical energy into electrical energy, and an optical fibre transforms light into an electric currentsee the photoelectric effect. What fuels can a diesel engine run on? This article is about the stationary engine. Petrol engines can often be adapted to also run on fuels such as liquefied petroleum gas and ethanol blends (such as E10 and E85).. 3. Nuclear Reactor Engineering: Reactor Systems Engineering,Springer; 4th edition, 1994, ISBN:978-0412985317, W.S.C. The Otto Cycle engine was eventually adopted to run on Ligroin and eventually gasoline, and many gases. So it is environment friendly engine. The cylinder arrangement of the compression engine was horizontal. The specific heat ratio of a gas (symbolized as gamma but also known as k) is commonly defined as the ratio of the specific heat of the gas at a constant pressure to its specific heat at a constant volume (see Equation 1). What is claimed is: 1. Gasoline is made up of light hydrocarbons with a high calorific value, which evaporate easily. The two cycles have different combustion processes : the diffusion (heterogeneous) burning of Diesel practically ensures that no methane escapes unburned from the combustion chamber. A typical engine cycle is defined in Fig. As was derived in the previous section, the thermal efficiency of an Otto cycle is a function of compression ratio and : In this equation, the displacement volume is equal to Vmax Vmin. The information contained in this website is for general information purposes only. . Internal combustion is a lot more efficient than external combustion, plus an internal combustion engine is a lot smaller. Therefore, the vast majority of Otto engines operate according to the 4-stroke operating cycle. 2. The Otto cycle is another example of a reversible cycle that only exists in theory. or gas can and oil can symbols on it. In 1876 Otto built an internal-combustion engine utilizing the four-stroke cycle (four strokes of the piston for each ignition). The gasoline engine is governed by the so-called Otto cycle or Beau de Rochas cycle. What fuels can a Otto engine run on? We study the Otto cycle to understand what takes place inside the internal combustion engine. MEP of a turbocharged diesel engine can range from 14 to 18 bar. . Although for a given compression ratio the Otto cycle has higher efficiency, because the Diesel engine can be operated to higher compression ratio, the engine can actually have higher efficiency than an Otto cycle when both are operated at compression ratios that might be achieved in practice. Efficiencies exceeding 47% have been routinely recorded. Internal combustion engines provide outstanding drivability and durability, with more than 250 million highway transportation vehicles in the United States relying on them. The Otto cycle is more complicated than a Carnot cycle, in a number of ways: The working gas is physically pumped in and out of the cylinder through valves, rather than being sealed and reused indefinitely as in the Carnot engine. The .5 hp (.37 kW) Otto-Langen engine created its power at 110 rpm at the flywheel with 40 power strokes per minute. The efficiency of Otto cycle is less as compared with the Diesel cycle. Nuclear Reactor Engineering: Reactor Systems Engineering,Springer; 4th edition, 1994, ISBN:978-0412985317, W.S.C. E. E. Lewis, W. F. Miller, Computational Methods of Neutron Transport, American Nuclear Society, 1993, ISBN: 0-894-48452-4. MEP of an atmospheric diesel engine can range from 7 to 9 bar. Introductory Nuclear Physics, 3rd Edition, Wiley, 1987,ISBN:978-0471805533, G.R.Keepin. W. M. Stacey, Nuclear Reactor Physics, John Wiley & Sons, 2001, ISBN: 0- 471-39127-1. The Otto Cycle engine was eventually adopted to run on Ligroin and eventually gasoline, and many gases. Why is Otto cycle considered the air standard cycle for spark ignition engines? Otto Cycle - Otto Engine. MEP of a turbocharged gasoline engine can range from 12 to 17 bar. The information contained on this website is for general information purposes only. What is the difference between Otto engine and diesel engine? a stationary engine using a coal gas-air mixture for fuel. In real engines, there are always some inefficiencies that reduce the thermal efficiency. What is the difference between Otto engine and diesel engine? After 14 years of research and development Otto succeeded in creating the compressed charge internal combustion engine May 9, 1876. The first torpedo to use it was the Mark 48 torpedo in the 1960s.[2][3]. peanut oil Rudolf Diesel's first compression ignition engines ran on peanut oil at the World Exposition in Paris. Other makers such as Daimler perfected the Otto engine for transportation use.[1][2][3]. The engine is limited to light fuels. This website does not use any proprietary data. The oil to fuel mix ratio should be specified in your engines instruction manual. The U.S. Department of Energy's Office of Scientific and Technical Information The truth is that OTTO engines have combustion at V = const (approximately) and can develop extremely high power and speed. Perhaps the most important is that it is inherently unstable and tends to explode under pressure, this makes it much more difficulty to store as it must be dissolved in acetone in an inert matrix, unlike say propane which can just be liquefied. In Otto injection-fed engines, gasoline is mixed with air by injecting it into the intake duct at the valve intake, or directly into the combustion chamber. H aving spent five years developing its new engine in Copenhagen and South Korea MAN ES has come out shouting about its performance and positioning in the market. Combustion chamberOtto cilco thermal engine. Main purpose of this project is to help the public learn some interesting and important information about engineering and thermal engineering. One of the key parameters of such engines is the change in volumes between the top dead center (TDC) to bottom dead center (BDC). Look at the fuel cap. Eventually, De Rochas won a certain sum of money, but Otto kept the fame and the name. 2) You may not distribute or commercially exploit the content, especially on another website. The expansion ratio of this engine was much more effective than that of the 1860 Lenoir engine and gave the engine its superior efficiency. This centralized distant heat dissipation system also helps to keep the engine building cool. Later engines dispensed with the fluted cylinder as well. The Otto Cycle engine was eventually adopted to run on Ligroin and eventually gasoline, and many gases. Visit our Editorial note. Gas engines are providing a wide range of fuel flexibility from burning natural gas and a variety of non- natural gaseous fuels from low British Thermal Unit (BTU) gases as well as gases containing a high hydrogen content. Which fuels can an Otto engine run on? 6 Diesel Cycle. It also has civilian applications as a solvent dye. The main difference between Otto cycle and Diesel cycle is that in Otto cycle heat addition takes place at constant volume and in diesel cycle heat addition takes places at constant pressure. Physics of Nuclear Kinetics. Cheaper than gasoline and diesel. We even left the plastic on the screen. Expansion. Compression The gas (fuel-air mixture) is compressed adiabatically from state 1 to state 2. Did Matthew Lewis Wear Prosthetic Teeth In Harry Potter? While Otto wanted to produce large engines for stationary applications Daimler wanted to produce engines small enough to be used in transportation. As can be seen, the MEP is useful characteristics of an engine. Marine diesel engines are very similar to the self-ignition engines in heavy-duty vehicles, but they are generally larger, more complex, and operate with higher efficiency. "Daimler: Founder of the Four-Wheeler", in Northey, Tom, ed. Glasstone, Sesonske. This means that the crankshaft must go around twice, and each piston moves up and down two times, to produce one pulse of power. Ultra-low-sulfur diesel (ULSD) is a diesel fuel with substantially lowered sulfur contents. The ideal Otto cycle consists of the following operations 1-2 Adiabatic compression. Gasoline is obtained from petroleum, a fossil fuel that is extracted from the ground. Modern portable engines excite the magneto with every flywheel rotation, and so use a cam-operated electric switch to prevent plug firing except for the power stroke of the engine (see wasted spark). The main difference between Otto cycle and Diesel cycle is that in Otto cycle heat addition takes place at constant volume and in diesel cycle heat addition takes places at constant pressure. The Otto cycle engine uses a spark to ignite a mixture of air and - traditionally - gasoline2compressed by the piston within the engine cylinder. Alcohols are unsuitable as diesel engine fuels because . One of key parameters of such engines is the change in volumes between top dead center (TDC) to bottom dead center (BDC). Building a Cloud Computing Career with Amazon AWS Certified Developer Azure Cognitive Services and Containers: 5 Amazing Benefits for Businesses, Running Your Own Electronics Accessories Ecommerce Store. The intake air is at 100 kPa = 1 bar, 20 C, and the chamber volume is 500 cm before the compression stroke. The Otto Cycle engine was eventually adopted to run on Ligroin and eventually gasoline, and many gases. This was soon dispensed with as the design was simplified. The Otto cycle engine uses a spark to ignite a mixture of air and traditionally gasoline2 compressed by the piston within the engine cylinder. A Carnot engine is, simply, a reversible engine acting between only two heat reservoirs. Which is more efficient Otto cycle or diesel cycle? The simple ideal Rankine cycle is in fact the most basic vapor power cycle. By 1889 more than 50 companies were manufacturing Otto design engines.[8]. In Otto injection-fed engines, gasoline is mixed with air by injecting it into the intake duct at the valve intake, or directly into the combustion chamber. The first inventor of the Otto engine, around 1862, was the Frenchman Alphonse Beau de Rochas. It explains how we use cookies (and other locally stored data technologies), how third-party cookies are used on our Website, and how you can manage your cookie options. Along with gasoline or diesel, they can also utilize renewable or alternative fuels (e.g., natural gas, propane, biodiesel, or ethanol ). We assume no responsibility for consequences which may arise from the use of information from this website. Peanut Biodiesel. Which is the best option to avoid knock in SI engine? Co; 1st edition, 1965. However, its major use is as a plasticizer in production of plastics, namely cellulose acetate butyrate, cellulose acetate propionate, polyvinyl butyral, polystyrene, and many synthetic rubbers. Fueltech FT550 ECU Open box special. NO new car marketed in the United States has been powered by a two-stroke engine since Saab phased out its hard-to-housebreak 3-cylinder in the late 1960s, when federal air pollution laws were taking hold. The working gas is not monoatomic. The fuel was still illuminating gas just as Lenoir's and his own atmospheric engines had used. Nicolaus August Otto as a young man was a traveling salesman for a grocery concern. The Dangers Of An Air-fuel . This system requires an external electric battery, ignition coil, and electric charging system similar to modern automobile engines. Save some $$$$ and buy this now before its gone. Although for a given compression ratio the Otto cycle has higher efficiency, because the Diesel engine can be operated to higher compression ratio, the engine can actually have higher efficiency than an Otto cycle when both are operated at compression ratios that might be achieved in practice. [6] While Daimler managed to improve production, the weakness in the Otto's vertical piston design, coupled to Daimler's stubborn insistence on atmospheric engines, led the company to an impasse. e.) Hot spots in the combustion chamber. For two engines of equal displacement volume, the one with a higher MEP would produce the greater net work and, if the engines run at the same speed, greater power. What is the difference between Otto cycle and diesel cycle? Explanation: The purpose of the carburetor is to supply petrol and air. A 4-cycle engine has two fill ports with each cap separately identifying the fuel tank from the oil sump. My car can run on diesel (the fossil fuel variety), straight vegetable oil (SVO), and biodiesel (SVO that has been modified), or any combination of the three.That isn't unusual: anything with a diesel engine -- plane, boat, motorcycle -- can run on diesel, SVO or biodiesel. In 1876, a German engineer, Nikolaus August Otto advanced the study of heat engines by building of the first working four-stroke engine. The chief component, propylene glycol dinitrate, accounts for approximately 76% of the mixture, while dibutyl sebacate and 2-nitrodiphenylamine account for approximately 22.5% and 1.5% (by weight), respectively.[6]. The Otto engine can also use gaseous fuels or liquefied gas as well, but its use is less practical and therefore much less widespread.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'demotor_net-box-4','ezslot_1',140,'0','0'])};__ez_fad_position('div-gpt-ad-demotor_net-box-4-0'); Gasoline is obtained from crude oil in a refinery. Otto's engine work during the eve of the industrial revolution was a critical development leading to the dawn of the automotive industry in the late 19th century. [4] It does not need exposure to any oxidant to ignite and release energy, as its three components will react among themselves whenever vaporised and heated. Otto cycle is used for petrol or spark ignition engine while diesel cycle is used for diesel or compression ignition engine. Dibutyl sebacate is a desensitizer in Otto fuel II. Otto Cycle It is the ideal cycle for spark ignition engines which has following processes considering air standard assumptions. Otto engines can be fueled by carburetion or injection. Rudolf Diesel's original engine was designed to run on coal dust and later the French government, who were at the time exploring the possibility of using peanut oil as a locally produced fuel in their African colonies, pioneered biofuels by specifying peanut oil as fuel for the engine he demonstrated at the 1900 "Exposition Universelle" in Paris. What type of cycle is used in steam engine? [citation needed] Daimler and Maybach founded a company known as Daimler Motorenwerke Gesellschaft which later merged with Benz to form Daimler-Benz, known also as Mercedes-Benz. By 1876 Otto and Langen succeeded in creating the first internal combustion engine that compressed the fuel mixture prior to combustion for far higher efficiency than any engine created to this time. A later development of this engine, known as the Diesel engine, can burn heavy fuels and oils. The Diesel cycle is a combustion process of a reciprocating internal combustion engine. The atmospheric engine has its power stroke delivered upward using a rack and pinion to convert the piston's linear motion to rotary motion. In 1886, the German patent office nullified the Deutz patent that would have run until 1891 due to the discovery of a previous patent for a four cycle engine by Frenchman Alphonse Beau de Rochas. Otto cycle The Otto Cycle is named after Nikolaus Otto (1832-1891, German) who is credited as the first creator of a petroleum fuel based internal combustion engine operating under a four stroke cycle. The network for one cycle can be calculated using the heat added and the thermal efficiency: Wnet = Qadd . However, the 2-stroke Otto cycle is little used because of the loss of mixture that occurs through the exhaust and the consequent high fuel consumption. Most petrol engines use spark ignition, unlike diesel engines which typically use compression ignition. Qadd = mcv (T3 T2) = 5.9510-4 x 718 x 1220 = 521.2 J. Wilhelm Maybach (1846-1929), one of the most important German engineers, perfected the construction, which was produced in large quantities already at the end of the year 1876. They called it diesel fuel in a brilliant bit of marketing. Otto = 521.2 x 0.5847 = 304.7 JMEP = 304.7 / (50010-6 55.56 10-6) = 685.6 kPa = 6.856 bar. The fuel is injected into the cylinder in both engines, but it is ignited with a spark plug in gasoline engines. The ECU was only used for a few Dyno pulls. Otto cycle is used for petrol or spark ignition engine while diesel cycle is used for diesel or compression ignition engine. The strokes are repeated over and over, generating power. During WWII Otto engines were run on more than 62 different fuels, such as wood gas, coal gas, propane, hydrogen, benzene, and many more. Due to the way the fuel ignites. In real engines, there are always some inefficiencies that reduce the thermal efficiency. In doing so he established the principle still in use today. Efficiencies exceeding 47% have been routinely recorded. If you want to get in touch with us, please do not hesitate to contact us via e-mail: The cycle of the Otto engine is called the Otto cycle. If either of these devices is out of whack, fuel/air mixture can get into the engine after shut-down, causing run-on. During WWII Otto engines were run on more than 62 different fuels, such as wood gas, coal gas, propane, hydrogen, benzene, and many more. Save my name, email, and website in this browser for the next time I comment. In the 15 years prior to the development of the Otto engine power output never exceeded 3 hp. During WWII Otto engines were run on more than 62 different fuels, such as wood gas, coal gas, propane, hydrogen, benzene, and many more. The fuel for an Otto engine is gasoline. [1] Daimler, which became Daimler-Benz, is the world's oldest automobile manufacturer. During WWII Otto engines were run on more than 62 different fuels, such as wood gas, coal gas, propane, hydrogen, benzene, and many more. Fuel efficiency: fuel efficiency tends to be slightly lower when using biodiesel due to the lower energy content of the fuel. When the engine speed increases, the governor pulls the small wheel to the right and the machine coasts without injecting any fuel, though the spark plug continues to fire with no fuel in the cylinder. Amazingly, the KLR starts and runs . If you want to get in touch with us, please do not hesitate to contact us via e-mail: [emailprotected]. The engine is limited to light fuels. Complete combustion of fuel-air mixture. A dual fuel engine can run on both diesel fuel and gaseous fuel. It can be used for plastics in use in the food packaging industry. Diesel Cycle or Constant Pressure Cycle Diesel cycle was introduced by Dr. Rudolph Diesel in 1897. Ignition is initiated through a gust generated by a, It distributes the fuel evenly in the various. This was the first commercially successful engine to use in-cylinder compression (as patented by William Barnett in 1838). The perfected system, for supplying different fuels to Otto engines with electronic fuel-injection comprises a tank (20) containing liquid gas (40) under pressure, a pumping unit (30) that delivers the liquid gas (40) to an injection nozzle (11) thad is also used for the injection of petrol.A signal multiplier (33), modifies the parameters fixed by an electronic control box (12) that controls . The diesel engine is an intermittent-combustion piston-cylinder device. How often does a 4-stroke engine make power to turn the crankshaft? Who Can Benefit From Diaphragmatic Breathing? The engine is limited to light fuels. January1993. For two engines of equal displacement volume, the one with a higher MEP would produce the greater net work and, if the engines run at the same speed, greater power. A signal multiplier (33), modifies the parameters fixed by an electronic control box (12) that controls . Other consequences are the increase of the fuel consumption and the pollutant emission. Among the two methods of laminating fuel, the most widely used is fueled by carburization. The Otto cycle is one of the most common thermodynamic cycles found in automobile engines and describes the functioning of a typical spark ignition piston engine. before producing the spark at the spark plug. In a 4-stroke engine, the five functions require four strokes of the piston (or two revolutions of the crankshaft). Visit our Privacy Policy page. These engines run small electric generators called diesel generators, often in remote areas as well as the engines of cars and trucks (both large and small). Nikolaus Otto is generally credited with building the first-four-stroke internal combustion engine in 1876. You are here These days, all cars and light trucks use four-stroke piston engines, whether burning gasoline or diesel. Wilhelm Maybach (1846-1929), one of the most important German engineers, perfected the construction, which was produced in large quantities already at the end of the year 1876. Otto and his manager Gottlieb Daimler had a major disagreement on the future direction of the Otto engine. K. O. Ott, R. J. Neuhold, Introductory Nuclear Reactor Dynamics, American Nuclear Society, 1985, ISBN: 0-894-48029-4. The average performance of a good Otto 4-stroke engine is 25 to 30%, lower than the performance achieved with a diesel engine. The four-stroke Otto cycle is made up of the following four internally reversible processes: 12, isentropic compression; 23, constant-volume heat addition; 34, isentropic expansion; and 41, constant-volume heat rejection. Needing no oxidants and being a stable substance makes Otto fuel II ideal for use in the constrained environment of a submarine. Otto engines were equipped with a number of different mechanism designs to trigger sparking. This engine ran on the fuel Ligroin, as did all vehicles until well past the year 1905. It is used gaseous fuels which are free from pollution. Contents 1 Types 2 Timeline 3 Atmospheric engine 4 The Otto cycle 4.1 Carburetor and low voltage Ignition Running rich can cause damage to an engine by washing the oil off of the cylinder walls. 1 Answer: Rangerman The Otto Cycle engine was eventually adopted to run on Ligroin and eventually gasoline, and many gases. The store will not work correctly in the case when cookies are disabled. As can be seen, the MEP is useful characteristics of an engine. The four strokes are intake, compression, combustion, and exhaust. Daimler's fourteen-year-old son Adolf was the first person to ride on this motorized bicycle which is the first internal combustion engined motor vehicle. Otto developed this machine in four- and two-stroke versions. [7] In 1882, after producing 2,649 engines, the atmospheric engine production was discontinued. In 1876, a German engineer, Nikolaus August Otto, advanced the study of heat engines by building the first working four-stroke engine. The temperature at the end of an adiabatic expansion is T4 = 800 K. At the beginning of calculations, we must determine the amount of gas in the cylinder before the compression stroke. Your email address will not be published. Thermal Efficiency Derivation A typical value for an air/fuel mixture is k = 1.35. In addition to its use by the United States Navy as a stabilizer in the manufacture of Otto fuel II, 2-nitrodiphenylamine is employed for similar purposes by the United States Army in the manufacture of double base solid propellants. An engine converts one form of energy (fuel) into mechanical energy. A low compression ratio does not require a high octane fuel to avoid this phenomenon, in the same way, a high compression requires a high octane fuel, to avoid the effects of detonation, that is, auto-ignition occurs. These heavier distillates are taken from crude oil after the more volatile portions used in gasoline are removed. Last edited on 13 September 2022, at 22:45, Learn how and when to remove this template message, Western Minnesota Steam Threshers Reunion, "125 Jahre Viertaktmotor | Oldtimer Club Nicolaus August Otto e.V. Daimler-Benz is one of the largest and most respected makers of luxury automobiles in the world. Another downside has to do with its low density . For a discussion of related thermodynamic principles, see. Let's look at the internal combustion process in more detail in the next section. In the traditional Otto cycle, the intake valves close at the bottom dead center (BDC), while in the Miller cycle, the intake valves closing (IVC) is advanced to ahead of the BDC making the expansion ratio larger than the compression ratio (CR) which reduces the compression work due to the advancement of intake valve Jul 18, 2021. Dual fuel engines operate with diesel-like performance Historically, one key reason diesel engines have been the top choice among oil and gas applications has been their solid performance. Question: Does Otto Cycle Use Absolute Pressure, Question: Does Otto Cycle Uses Isobaric Process, Quick Answer: How Does The Otto Cycle Begin, Quick Answer: What Are Carnot Cycle Otto Cycle And Diesel Cycle, Do Two Stroke Lawn Mowers Use The Otto Cycle, Question: Does The Otto Cycle Affect The Environment Through Greenhouse Gases, Quick Answer: Does The Otto Or Desiel Cycle Produce Higher Combustion Temps. Carburetted gasoline engines working on Otto cycle can work with compression ratios more than Of these statements (a) 1, 3 and 4 are correct (b) 1, 2 and 3 are correct (c) 1, 2 and 4 are correct (d) 2, 3 and 4 are correct Q19. 5 The Internal combustion engine (Otto Cycle) [VW, S & B: 9.13] The Otto cycle is a set of processes used by spark ignition internal combustion engines (2-stroke or 4-stroke cycles). Although for a given compression ratio the Otto cycle has higher efficiency, because the Diesel engine can be operated to higher compression ratio, the engine can actually have higher efficiency than an Otto cycle when both are operated at compression ratios that might be achieved in practice. Diesel engines are more efficient and use 1520% less fuel translating into cheaper running costs. This research has shown that it is possible to increase operating efficiency, and therefore fuel efficiency and range using the TONE concept. The cap will usually state the oil to fuel mix ratio. In Otto cycle as well as in diesel cycle heat rejection takes place at constant volume. When running in gas mode, the engine works according to the Otto process where the lean airfuel mixture is fed to cylinders during the suction stroke. There are certainly a few reasons why acetylene is not a very practical fuel for an IC engine. The engines were initially used for stationary installations, as Otto had no interest in transportation. Peanuts are a powerful source of biofuel as they contain about 50% oil by weight.
