A petrol engine ( gasoline engine in American and Canadian English) is an internal combustion engine designed to run on petrol ( gasoline ). Petrol engines can often be adapted to also run on fuels such as liquefied petroleum gas and ethanol blends (such as E10 and E85 ).
11-434: (Redirected from Vortec ) Line of gasoline truck engines Vortec is a trademarked name for a line of gasoline engines for General Motors trucks . The name first appeared in an advertisement for the 1985 model year 4.3 L V6 that used "vortex technology" to create a vortex inside the combustion chamber , creating a better air / fuel atomization. It has since been used on

33-442: A type of engine used to start a larger, stationary diesel engine. Spark-ignition engine A spark-ignition engine ( SI engine ) is an internal combustion engine , generally a petrol engine , where the combustion process of the air-fuel mixture is ignited by a spark from a spark plug . This is in contrast to compression-ignition engines , typically diesel engines , where the heat generated from compression together with

55-627: Is different from Wikidata All set index articles Gasoline engine Most petrol engines use spark ignition , unlike diesel engines which typically use compression ignition. Another key difference to diesel engines is that petrol engines typically have a lower compression ratio . The first practical petrol engine was built in 1876 in Germany by Nicolaus August Otto and Eugen Langen , although there had been earlier attempts by Étienne Lenoir in 1860, Siegfried Marcus in 1864 and George Brayton in 1873. Most petrol engines use either

88-532: The four-stroke Otto cycle or the two-stroke cycle . Petrol engines have also been produced using the Miller cycle and Atkinson cycle . Most petrol-powered piston engines are straight engines or V engines . However, flat engines , W engines and other layouts are sometimes used. Wankel engines are classified by the number of rotors used. Petrol engines are either air-cooled or water-cooled . Petrol engines use spark ignition . High voltage for
99-642: The fuel primer helps because otherwise there will not be enough heat available to vaporize the fuel in the carburetor . The power output of small- and medium-sized petrol engines (along with equivalent engines using other fuels) is usually measured in kilowatts or horsepower . Typically, petrol engines have a thermodynamic efficiency of about 20-30% (approximately half that of some diesel engines). Applications of petrol engines include automobiles , motorcycles , aircraft , motorboats and small engines (such as lawn mowers, chainsaws and portable generators). Petrol engines have also been used as "pony engines",
110-759: The injection of fuel is enough to initiate the combustion process, without needing any external spark. Spark-ignition engines are commonly referred to as "gasoline engines" in North America, and "petrol engines" in Britain and the rest of the world. Spark-ignition engines can (and increasingly are) run on fuels other than petrol/gasoline , such as autogas ( LPG ), methanol , ethanol , bioethanol , compressed natural gas (CNG), hydrogen , and (in drag racing) nitromethane . The working cycle of both spark-ignition and compression-ignition engines may be either two-stroke or four-stroke . A four-stroke spark-ignition engine
121-519: The spark this may be provided by a magneto or an ignition coil . In modern car engines, the ignition timing is managed by an electronic Engine Control Unit . Ignition modules can also function as a rev limiter in some cases to prevent overrevving and the consequences of it, such as valve float and connecting rod failure. Primers may be used to help start the engine. They can draw fuel from fuel tanks and vaporize fuel directly into piston cylinders. Engines are difficult to start during cold weather, and
