4 Stroke Diesel Engine

Page history last edited by Ms. K. Diaz 14 years, 1 month ago

Intake stroke -- The intake valve opens up, letting in air-fuel and moving the piston down.

Compression stroke -- The piston moves back up and compresses the air-fuel.

Combustion stroke -- As the piston reaches the top, fuel is injected at just the right moment and ignited, forcing the piston back down.

Exhaust stroke -- The piston moves back to the top, pushing out the exhaust created from the combustion out of the exhaust valve

Diesel engines and gasoline engines are quite similar.They are both internal combustion engines designed to convert the chemical energy available in fuel into mechanical energy.

This mechanical energy moves pistons up and down inside cylinders. The pistons are connected to a crankshaft, and the up-and-down motion of the pistons, known as linear motion, creates the rotary motion needed to turn the wheels of a car forward.
