Description

 

Diesel Engine Principle and Working Cycle Explained:


Basically, there are two types of diesel engine types - the Four Stroke and Two Stroke. The 'Diesel Cycle' uses higher Compression-Ratio. It was named after German engineer Rudolph Diesel, who invented and developed first Four-Stroke diesel engine.

 

The four strokes of the diesel cycle are similar to that of a petrol engine. However, the 'Diesel Cycle' considerably defers by the way the fuel system supplies the diesel the engine and ignites it.


A conventional internal combustion diesel engine works on 'Diesel Cycle'. In the simple diesel engines, an injector injects diesel into the combustion chamber above the piston directly. The 'Compression-Ignition engine' is also another name for the Diesel engine. This is mainly because it burns the diesel with hot and compressed air.

 

The temperature of the air inside the combustion chamber rises to above 400°c to 800°c. This, in turn, ignites the diesel injected into the combustion chamber. Thus, the 'Diesel Cycle' does not use an external mechanism such as a spark-plug to ignite the air-fuel mixture.

 

Start

 

A small number use resistive grid heaters in the intake manifold to warm the inlet air until the engine reaches operating temperature. Engine block heaters (electric resistive heaters in the engine block) plugged into the utility grid are often used when an engine is shut down for extended periods (more than an hour) in cold weather to reduce startup time and engine wear.

 

governor

 

A vital component of any diesel engine system is the governor, which limits the speed of the engine by controlling the rate of fuel delivery. Unlike a petrol (gasoline) engine, the incoming air is not throttled, so the engine would overspeed if this was not done. Older governors were driven by a gear system from the engine (and thus supplied fuel only linearly with engine speed). Modern electronically-controlled engines achieve this through the electronic control module (ECM) or electronic control unit (ECU) - the engine-mounted "computer".

 

The ECM/ECU receives an engine speed signal from a sensor and then using its algorithms [1] and look-up calibration tables stored in the ECM/ECU, it controls the amount of fuel and its timing (the "start of injection") through electric or hydraulic actuators to maintain engine speed.
