Description

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.

Cycle of Operation

(i). Otto cycle engine: These types of engine works on Otto cycle.

(ii). Diesel cycle engine: The engine working on diesel cycle is called diesel cycle engine.

(iii). Dual cycle engine or semi-diesel cycle engine: The engine that works on both diesel as well as Otto cycle is called dual cycle engine or semi diesel cycle engine.

Number of Strokes

On the basis of number of stroke, the types of engine are:

(i). Four Stroke Engine: It is an engine in which the piston moves four times i.e.2 upward (form BDC to TDC) and 2 downward (from TDC to BDC) movement in one cycle of power stroke is called four stroke engines.

Different Types of Engine

Four Stroke Engine

(ii). Two Stroke Engine: The engine in which the piston does two times motion i.e. one from TDC to BDC and other from BDC to TDC to produce a power stroke is called two stroke engines.

Different Types of Engine

Two Stroke Engine

(iii). Hot spot ignition engine: This type of engine is not in practical use.

Type of Ignition

On the basis of ignition, the engines are classified as:

(i). Spark ignition engine (S.I. engine):

In spark ignition engine there is a spark plug which is fitted at the engine head. The spark plug produces spark after the compression of the fuel and ignites the air fuel mixture for the combustion. The petrol engines are spark ignition engine.

(ii). Compression ignition engine (C.I. engine):

In Compression ignition engine there is no spark plug at the cylinder head. The fuel is ignited by the heat of the compressed air. The diesel engines are compression ignition engine.
