UNIT-I
BASIC THEORY
INTRODUCTION
Definition of ‘Engine’
An engine is a device, which transforms one form of energy into another form. Normally, most of the engines convert thermal energy into mechanical work and therefore they are called ‘heat engines’.

Heat engines can be broadly classified into two categories:
i. Internal Combustion Engines (IC Engines)
ii. External Combustion Engines (EC Engines)

External Combustion and Internal Combustion Engines
External combustion engines are those in which combustion takes place outside the engine whereas in internal combustion engines combustion takes place within the engine.
For example, in a steam engine or a steam turbine, the heat generated due to the combustion of fuel is employed to generate high pressure steam, which is used as the working fluid in a reciprocating engine or a turbine. In case of gasoline or diesel engines, the products of combustion generated by the combustion of fuel and air within the cylinder form the working fluid.

Application of IC and EC Engines

IC Engines
1. GASOLINE ENGINE –AUTOMOTIVE, MARINE AIRCRAFT
2. DIESEL ENGINE - AUTOMOTIVE, MARINE,POWER,LOCOMATIVE
3. GAS ENGINES –INDUSTRIAL POWER

EC Engines
1. STEAM ENGINES – LOCOMOTIVES,MARINE
2. STEAM TURBINE – POWER,LARGE MARINE
