Basic 4-stroke diesel principles
|
The 4-stroke diesel engine operates with the 5 events common to all internal combustion engines: Intake, Compression, Ignition, Power, Exhaust.
|
4-stroke diesel engine cycle
|
In a 4-stroke diesel engine, the piston travels one stroke each for intake, compression, power, and exhaust. A stroke is the distance from top dead centre to bottom dead centre.
|
Basic 2-stroke diesel principles
|
The 2-stroke diesel engine is an internal combustion engine with the 5 events common to all such engines: Intake, Compression, Ignition, Power, Exhaust.
|
2-stroke diesel engine cycle
|
The 2-stroke diesel engine uses all of the 5 events in just 2-strokes. The crankshaft makes one revolution for each engine cycle.
|
| Three phases of combustion |
The combustion process in the cylinder of a CI engine is usually described in three phases. |
