Engine type
An engine is a machine that converts chemical energy into mechanical energy. It can be divided into internal combustion engines and external combustion engines according to the position of the combustion chamber, and internal combustion engines are used in the field of automobile engines. So what are the types of internal combustion engines for the automotive engine field?
Reciprocating piston engine
The reciprocating piston engine is an engine that converts the piston's reciprocating linear motion in the cylinder from the crank connecting rod assembly to the rotational motion of the crankshaft, and thereby outputs torque to the outside. The reciprocating piston technology is mature, and it is widely used in the field of automobile engines.
Rotary engine
The rotary engine can directly drive the piston to rotate in the cylinder by the expansion force of fuel combustion through the special-shaped cylinder and piston. Compared with the reciprocating piston engine, the rotary engine has the advantages of small size, light weight, and low center of gravity. However, its shortcomings are also very obvious, that is, high fuel consumption and emissions, serious pollution, and short engine life. At present, only Mazda is still investing in research and development.
In-line cylinder engine
The cylinders of an in-line cylinder engine are arranged in line, which is currently the most common form of engine layout.
V engine
The V-type engine divides the engine cylinders into two groups, arranged at an angle of less than 180 degrees, and is mostly used in engines with more than 4 cylinders.
Horizontally opposed engine
When the cylinder angle is equal to 180 degrees, it is a horizontally opposed engine. The advantage of this engine is its low center of gravity and stable operation.
According to different fuels, it can be divided into: gasoline engine, diesel engine and other fuel engines
According to whether there is supercharging, it can be divided into: supercharged engine and naturally aspirated engine
