Basic Structure Of Bus Engine

Basic Structure Of Bus Engine
The bus engine is a complex machine, which includes many mechanisms and systems. Different types of engines have different specific structures, but their basic structures are similar.
The gasoline engine is composed of crank connecting rod mechanism, valve train and fuel system, cooling system, lubrication system, starting system and ignition system, which are commonly referred to as two mechanisms and five systems. The diesel engine is compression ignition, so there is no ignition system.

The function of the crank connecting rod mechanism is to support all parts of the engine and convert the gas pressure of the piston crown into the torque of the crankshaft for external output.

The function of the valve distribution mechanism is to open and close the inlet and exhaust valves regularly according to the requirements of the engine, so as to inhale clean air and exhaust waste gas.Common accessories aree intake valve and exhaust valve accessories.

The function of the fuel supply system is to supply the required fuel regularly and quantitatively according to the working requirements of the engine.
Common accessories are fuel pumps.

The function of the ignition system is to ignite the combustible mixture in the cylinder of the gasoline engine at the specified time.

The function of the lubrication system is to lubricate, seal, clean and cool.

The function of the cooling system is to keep the engine working at a suitable temperature.

The function of the starting system is to start the engine.
