What are the eight classifications of engines?

Engines can be classified into eight types: gasoline engines, diesel engines, gas engines, steam engines, steam turbines, hot air engines, gas turbines, and jet engines. Engine classification methods: Classification based on different piston movement methods, classification according to the type of fuel used, classification by cooling method, classification by the number of piston strokes during a working cycle, classification by the number of cylinders, classification by cylinder arrangement, and classification by intake state. Brief description of classifications: In general, most engines used in automobiles are distinguished by the type of fuel used, such as gasoline engines, diesel engines, gas engines, steam engines, etc. They can also be classified by the number of cylinders, which includes single-cylinder and multi-cylinder engines. Single-cylinder and twin-cylinder engines are mainly used in motorcycles and agricultural machinery, while automobiles typically use multi-cylinder engines, such as three-cylinder, four-cylinder, five-cylinder, six-cylinder, eight-cylinder, ten-cylinder, and twelve-cylinder engines. Currently, three-cylinder engines are very popular and are mostly used in small-displacement passenger cars. Five-cylinder and ten-cylinder engines are relatively rare. Examples of vehicles using five-cylinder engines include the Audi 100, Audi RS3, Audi TTRS, and Volvo T5. Ten-cylinder engines are usually designed in a V-configuration and were used in early F1 racing cars, as well as in the T815 ten-cylinder air-cooled engine.
As a new car owner, I recently researched vehicles and discovered that engine classifications are incredibly diverse, with eight main types. First is fuel type: gasoline and diesel dominate currently, but electric and hybrid are gaining popularity, each offering distinct experiences. Second is cylinder arrangement: inline engines are easier to maintain, while V-types save space. Third is working cycle: four-stroke is stable, whereas two-stroke is seen in older vehicles. Fourth is ignition method: gasoline engines use spark plugs, while diesel relies on compression. Fifth is cooling system: liquid-cooled (common in sedans) vs. air-cooled. Sixth is intake method: naturally aspirated runs quietly, turbocharged delivers robust power. Seventh is cylinder count: from single-cylinder to multi-cylinder, affecting acceleration. Eighth is application type: family cars and high-performance vehicles have different engine designs. Understanding these helps match a car's personality—I now feel more confident driving, especially when choosing eco-friendly options like zero-emission electric vehicles.
