Internal Combustion Engines
Engine: a device that transforms different forms of energy
Heat Engine: a device that transforms chemical energy of fuel into thermal energy which is utilised to perform useful mechanical work
CLASSIFICATION OF HEAT ENGINES
IC Engine
Combustion process takes place inside the cylinder
Reciprocating IC Engine
that uses one or more reciprocating pistons to convert pressure into a rotating motion
Spark ignition
Compression ignition
Stationary Parts
Engine Cylinder block
Cylinder Head
Crank case
Inlet manifold
Exhaust manifold
Gaskets
MOVING PARTS OF AN ENGINE
Piston Assembly
Crank Shaft
Working of an IC Engine
Four Stroke Combustion Cycle
Intake Stroke
