What components are included in the engine assembly

The engine assembly classification
Automobile engines generally obtain kinetic energy by internally burning gasoline (diesel), so the automobile engine is an internal combustion engine.

1.   According to the fuel used: it can be divided into gasoline engine and diesel engine.   Gasoline engine and diesel engine have their own characteristics;   gasoline engine has high speed, low quality, low noise, easy starting and low manufacturing cost;   diesel engine has large compression ratio, high thermal efficiency, and emission performance and economic performance are much better than gasoline engine.

2.   According to the piston movement mode: the piston type internal combustion engine can be divided into two types: reciprocating piston type and rotary piston type.   The former piston reciprocates linearly in the cylinder, and the latter piston rotates in the cylinder.

3, according to the number of cylinders: can be divided into single-cylinder engines and multi-cylinder engines.   An engine with only one cylinder is called a single cylinder engine;   an engine with more than two cylinders is called a multi-cylinder engine.   Modern car engines use three-cylinder, four-cylinder, six-cylinder and eight-cylinder engines.

4.   Classification according to cooling method: The internal combustion engine can be divided into water-cooled engine and air-cooled engine according to different cooling methods.   The water-cooled engine is cooled by using a coolant circulating in the cylinder block and the cylinder head cooling jacket as a cooling medium;   and the air-cooled engine uses air flowing between the cylinder block and the fin on the outer surface of the cylinder head as a cooling medium.   Cooling.   The water-cooled engine is evenly cooled, reliable in operation and good in cooling effect, and is widely used in modern vehicle engines.
