     Main Engine units

Diesel Engine (4 Stroke)

1.Only air entered in the cylinder during suction stroke.

2.Piston compresses the air at high pressure that increases high temperature.

3.Diesel is injected in to the compressed and hot air by Injector.

4.Burnet  gases escaped out

Petrol Engine (4 Stroke)

1. Air and Fuel are mixed together and sucked-in during intake stroke.

2. Piston compresses the mixture at compression stroke.

3. the spark at the spark plug ignites the air-fuel mixture, which forces the piston downward

4. Burnt gases escaped out

Operation of Engine

Internal Combustion Engine
