What is an EngineWhat is an EngineAny device which can convert heat energy of fuel into mechanical energy is known as engine or heat engine.

•Gasoline Engine

•Diesel Engine

•Rotary Engine

•Steam Engine

Cylinder block or Cylinder are main part of an engine. It is a part in which combustion of fuel takes place

Piston is placed in the cylinder and transmits thrust to the connecting rod

Cylinder head is fitted on the top of cylinder block and the function of the cylinder head is to seal the working end of cylinder and not to permit entry and exit of gases on cover head valves of the engine

Connecting rod connects piston to the crank shaft and transmit the motion and thrust of piston to crank shaft

Crank shaft is located in the bottom end of cylinder block. It transmits the reciprocating motion of piston into rotary motion

Oil sump is bolted at the lower end of the cylinder block. All the oil for lubricating the movable parts is placed in it.

Cam shaft is fitted either in the cylinder head or at the bottom of the cylinder block. It is use to open or close valves at proper timing in multi-cylinder engine.

Valves are fitted on the cylinder head. It regulates the flow of air fuel mixture inside the cylinder and exhaust gas outside the cylinder block

It is used in Petrol engine (Spark Ignition Engine)  It is fitted on the cylinder

head. It is used to inject fuel in spray form inside the cylinder at the end of compression stroke.

 Its function is to evenly distribute air-fuel mixture for intake & collects the exhaust gases from all cylinders.

It provides the good sealing fit and less friction resistance between piston and cylinder

It is used to seal the cylinder head and cylinder so no pressure is allowed to escape

It connects the piston to the connecting rod

Bearings are used to support the moving parts

Four Stroke Engine How it Works.mp4

 In the four-stroke engine the cycle of operations of the engine are completed in four strokes of the piston inside the cylinder. The four strokes of the 4-stroke engine are: suction of fuel, compression of fuel, expansion or power stroke, and exhaust stroke
