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
On the basis of cycle of operation the engine types are:
(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.
