Engine Technologies-Four stock Diesel Engine

How diesel four stock engine work

Diesel four stock engines have four steps. Because of these four steps power will generate in the engine .these stocks are

1. Intake Stroke 
2. Compression Stroke 
3. Power Stroke 
4. Exhaust Stroke

Main components of diesel four stock engine

Main components of diesel four stock engine

E- Exhaust valve

I-Inlet Valve

S-Injector

P-Piston

How diesel four stock engine work

Intake Stroke

Intake Stroke

This is a first stock in diesel engine. In here inlet value has opened Exhaust valve has closed. All air comes into the cylinder. In here piston goes to up to down

Compression Stroke

Compression Stroke

In this step piston goes to down to up.in here inlet and Exhaust valve has closed. All air in the cylinder is compress when the piston goes to up. The compression ratio is 20:1, 18:1

Power Stroke

Power Stroke

This is a important stock in four stock engine. Both valves are closed .Power is generate in this step. When the piston reach the top of the cylinder,Injecter spray diesel to heated, Compressed air. Then diesel burn. Because of that power is generate and piston goes to down high speed.

Exhaust Stroke

Exhaust Stroke

This is last step of four stock engine.In here inlet value has closed Exhaust valve has opened. All combustion air from Power Stroke is exhaust from this stock.in this stock piston goes to down to up.
