Engine

Engine:

An Engine is a device which transform one form of energy into another form, the efficiency of conversion plays an important role. Normally, most of the engine convert thermal energy into mechanical work and therefore they called Heat Engine.

Heat Engine:

Heat Engine is a device which transform the chemical energy of a fuel into thermal Energy and utilizes this thermal energy to perform useful work. Thus, thermal energy is converted to mechanical energy in a heat engine.

Heat Engine can be broadly classified into two categories:

1. Internal Combustion Engines (IC Engine)
2. External Combustion Engines (EC Engines)

Again Internal and External Engines are divided into two parts

1. Reciprocating Engines
2. Rotary Engines
   

External Combustion Engines:

External Combustion engine are those in which combustion takes place outside the engines.

Internal Combustion Engines:

Internal Combustion Engines are those in which Combustion takes place within Engines.

Four - Stroke Engine:

For produce power in a internal combustion engine, it has to follow some operations in a sequential manner viz., suction, compression, combustion, expansion and exhaust. In which engine these operations are completed in four stroke is called four stroke engine.

Two - Stroke Engine:

In which engine above five operations are completed in two stroke is called two stroke engine.
