Detailed engineering on Engine!
Hi Everyone,
i know how an engine works. What i want to know is what are the materials used for engineering a engine. Like the material of cylinder block, crank case, cylinder, valves, piston, cam shaft etc. I want the reason behind the selection of the materials. I need it briefly ๐

viky1147Thanks sir! Will go through it

mechkycylinder block - grey cast iron/cast iron alloyed with nickel & chromium/aluminium alloy
crankcase - alloy cast iron/plastics
cylinder - cast iron/aluminium alloyed with silicon
valves - chromium-silicon steel(silchrome & volmax) also known as valve steel
piston - alloy cast iron/aluminium alloy
camshaft - alloy cast iron -
Al-OtaibyHere you go buddy ๐
-Cylinder block in old engines and diesel engines are made of grey cast iron (it can take high compression)
-Cylinder block in air cooled engines and new engines are made of Aluminium alloy (It gains and looses heat rabidly)
-Oil pan is made of steel plate (it looses heat fast and can resist hits)
-Pistons are made of Aluminuim alloy in normal cars and from gery cast iron mixed with aluminuim alloy in new and sport cars (better heat treatment and can take compressions)
-oil rings are made of steel chips for flexibility
-compression rings are made of steel
-Piston arms are made of tempered and normalised steel for high bending torque.
-Crankshaft is made of steel or cast iron with spherical graphite requirements and to achieve high resistance to stresses often used Hardening Alloy Steel.
-Flywheel Made of steel cast-iron mixture
If you need anything else please don't hesitate to contact me. -
viky1147Thanks a lot both of you ๐ Hats off!

Wat about Valves, Gears, Chasis?
And wats the difference between Gray cast iron and cast iron? -
CE DesignerCast Iron is formed from Iron-carbon alloys having a very high percentage of carbon.
In gray cast iron the excess carbon forms graphite flakes in the microstructure whilst in white cast iron the excess carbon forms cementite which makes white cast iron extremely hard and brittle, more so than gray. -
zaverigray cast iron has granules of graphite in it which constitutes the pearlite

but anyways, we use steel as its material
