Due to compression, the pressure and temperature of the charge are increased.The piston moves from BDC to TDC, thus compressing air petrol mixture. This stroke is represented by the line AB on the P-V diagram.Ĭompression Stroke: During compression stroke, both inlet & exhaust valves are closed. The piston moves from TDC to BDC, drawing a fresh charge of vaporized fuel-air mixture.

Suction Stroke: During the suction stroke, inlet valve is In a 4-Stroke petrol engine, the charge admitted into the engine cylinder is a homogeneous mixture of petrol and air.ĭepending on the load on the engine, petrol and air is mixed in proper proportions and sent into the cylinder by a popular device known as “carburettor”. Since ignition in these engines is due to a spark, they are also called Spark Ignition Engines (S.I. Exhaust stroke A spark plug is used to produce a spark so as to ignite the charge inside the cylinder. The piston performs four strokes to complete one working cycle.

Engines) Combustion of fuel takes place outside the engine cylinder. Engg.Ĭlassification of Heat Engines Heat Engines may be classified as:ġ. Note: Prime Mover is a device which utilizes a natural source of energy to produce rotary mechanical energy. Mechanical work produced in Heat Engines is Linear Work (Motion) which is converted into Rotary Work (Motion) by elements such as cylinder, piston, connecting rod, crank, etc. Heat Engine Heat Engine is a prime mover which derives the heat energy from combustion of fuel or any other source and converts this energy into mechanical work.
