Engine- Functions Of Important Parts In Internal Combustion Engine.
77Internal 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,a 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 crank shaft 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.

my name is thomas i want to no more on automobil engine and also to learn
thanksssss
l also went to lean more about engines and there ways of functioning
iam in uganda (muwanguzijoseph68@yahoo.com
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
Excellent definitions above. For additional diesel engine parts go to http://www.partznetwork.com
thanks alot from the note i really like it but some parts are missing in this like bearing and sidecovers breather and cb point
thanks im doin a cert II in auto and this is helping alot
Thanks a lot for nice comments.
your research is reccomendable and keep it up
very good info helped me alot
ver good information
someone tel me if why we need fuel to make the engine in our car moved? while we know that it cause of danger like pollution.
thanks.let me know about the fuction of crankshaft gear.
not enough information
really, Very nice
its realy very nice and useful for me i am working in automobile industry as a technician
Thanks 4 d information. I want 2 know what is d value timing of a diesesl engine
Thanx....its a very very useful for me..!
I have learnt more through this forum .Thanks alot
meaningfull defination. But material used for every part is not given.
Very nice its use to increase our knowledge
thanx a lot.....
Im a maritime student researching all about diesel engine and it helps me a lot....
thank you.....
thanks alone......
nice easy to understand much better
Very Nice information for easy to understand.
nice one.....it helped a lot
tanks
Thankss for infarmation
whose the author of this?
thank you so much .., God bless you
i dont understant
very nice
Wow eeeverything is nice eventhough i have just started to study about da automobile i op i like it.
i am abish.i complete diplomo in auto mobile engineering.but i read in automobile books not understand.i read this information now easily understad that. so thanks for give this information
very nice thank you a lot if you can give me information about cooling and lubrication system
Dat was good but if any reader want to get more from an experienced person,text me on mailjoemarine@yahoo.com.
