Engine- Functions Of Important Parts In Internal Combustion Engine.

Internal combustion engines are made from various parts.Each part has its own location and function for proper working of engine.Some important parts and its function is as described below. It is most essential to know right information from engineering person.

01) Cylinder Block

Function- In the bore of cylinder the fresh charge of air-fuel mixture is ignited,compressed by piston and expanded to give power to piston.

02) Cylinder Head

Function-It carries inlet and exhaust valve.Fresh charge is admitted through inlet valve and burnt gases are exhausted from exhaust valve.In case of petrol engine,a spark plug and in case of diesel engine,an injector is also mounted on cylinder head.

03) Piston

Function-During suction stroke,it sucks the fresh charge of air-fuel mixture through inlet valve and compresses during the compression stroke inside the cylinder.This way piston receives power from the expanding gases after ignition in cylinder.Also forces the burnt exhaust gases out of the cylinder through exhaust valve.

04) Piston Rings

Function-It prevents the compressed charge of fuel-air mixture from leaking to the other side of the piston.Oil rings,is used for removing lubricating oil from the cylinder after lubrication.This ring prevents the excess oil to mix with charge.

05) Connecting Rod

Function-It changes the reciprocating motion of piston into rotary motion at crankshaft.This way connecting rod transmits the power produced at piston to crankshaft.

06) Gudgeon Pin

Function-Connects the piston with small end of connecting rod.

07) Crank Pin

Function-hand over the power and motion to the crankshaft which come from piston through connecting rod.

08) Crank Shaft

Function-Receives oscillating motion from connecting rod and gives a rotary motion to the main shaft.It also drives the camshaft which actuate the valves of the engine.

09) Cam Shaft

Function-It takes driving force from crankshaft through gear train or chain and operates the inlet valve as well as exhaust valve with the help of cam followers,push rod and rocker arms.

10) Inlet Valve & Exhaust Valve

Function-Inlet valve allow the fresh charge of air-fuel mixture to enter the cylinder bore.Exhaust valve permits the burnt gases to escape from the cylinder bore at proper timing.

11) Governor

Function-It controls the speed of engine at a different load by regulating fuel supply in diesel engine.In petrol engine,supplying the mixture of air-petrol and controlling the speed at various load condition.

12) Carburettor

Function-It converts petrol in fine spray and mixes with air in proper ratio as per requirement of the engine.

13) Fuel Pump

Function-This device supply the petrol to the carburettor sucking from the fuel tank.

14) Spark Plug

Function-This device is used in petrol engine only and ignite the charge of fuel for combustion.

15) Fuel Injector

Function-This device is used in diesel engine only and delivers fuel in fine spray under pressure.

I hope,above information will help you something about your vehicle's engine.

the internal combustion is important because this is the one of the most important parts of an engine because it is use to the expansion of the high temperature and pressure gasses, which are produced by combustion dirrect applies force to component of the engine such as piston or turbize bladders or a nozzles

Heyy i am mechanical Engineer. There's a question of Someone that how crankshaft Work?

Ans: Crank shaft receives oscillating motion from conecting rod & gives a rotating motion to the main shaft. It also drives the cam shaft which actuate the valves of the Engine.
