About The Tutomobile Engine

The car engine is the device that powers the car, is the heart of the car, determining the dynamics, economy, stability and environmental protection of the car. According to the power source, the car engine can be divided into diesel engine, gasoline engine, electric vehicle electric motor and hybrid power, etc.
Common gasoline engines and diesel engines belong to reciprocating piston type internal combustion engines, which convert the chemical energy of the fuel into the mechanical energy of the piston movement and output the external power. Gasoline engines are high speed, low quality, low noise, easy to start, low manufacturing costs; diesel engines have a large compression ratio, high thermal efficiency, economic performance and emission performance are better than gasoline engines.

Classification
According to the way the intake system works, it can be divided into four types of natural intake, turbocharged, mechanical supercharged and double supercharged.
By the piston movement mode can be divided into reciprocating piston internal combustion engine and rotary piston engine.
By cylinder arrangement type divided into straight-line engine, V-type engine, W-type engine and horizontal opposite engine, etc.
According to the number of cylinders, it can be divided into single-cylinder and multi-cylinder engines. Modern cars use three-cylinder, four-cylinder, six-cylinder and eight-cylinder engines.
According to the different cooling method can be divided into water-cooled engine and air-cooled engine. Water-cooled engine is evenly cooled, reliable work, good cooling effect, is widely used in modern automotive engines.
By the number of strokes can be divided into four-stroke internal combustion engine and two-stroke internal combustion engine. Automotive engines are widely used four-stroke internal combustion engine.
Classified by fuel supply: carburetor engines and electric injection engines and in-cylinder direct injection engines.
