Description

 

Working of Four Stroke Diesel Engine


The power generation process in four stroke diesel engine is also divided into four parts. Each part is known as piston stroke. In IC engine, stroke is referred to the maximum distance travel by the piston in a single direction. The piston is free to move only in an upward and downward direction. In four stroke engine the piston move two time up and two time down and the crankshaft move two complete revolution to complete four piston cycle. These are suction stroke, compression stroke, expansion stroke, and exhaust stroke.

 

Suction stroke:


In the suction stroke or intake stroke of diesel engine, the piston start moving from top end of the cylinder to bottom end of the cylinder and simultaneously inlet valve opens. At this time air at atmospheric pressure drawn inside the cylinder through the inlet valve by a pump. The inlet valve remains open until the piston reaches the lower end of the cylinder. After it, inlet valve close and seal the upper end of the cylinder.

 

Compression stroke:


After the piston passes the bottom end of the cylinder, it starts moving up. Both valves are closed and the cylinder is sealed at that time. The piston moves upward. This movement of the piston compresses the air into a small space between the top of the piston and cylinder head.

 

The air is compressed into 1/22 or less of its original volume. Due to this compression, a high pressure and temperature generated inside the cylinder. Both the inlet and exhaust valves do not open during any part of this stroke. At the end of compression stroke the piston is at top end of the cylinder.

 

Power stroke:


At the end of the compression stroke when the piston is at the top end of the cylinder a metered quantity of diesel is injected into the cylinder by the fuel injector. The heat of compressed air ignites the diesel fuel and generates high pressure which pushes down the piston. The connecting rod carries this force to the crankshaft which turns to move the vehicle. At the end of the power stroke, the piston reaches the bottom end of the cylinder.
