An automobile engine is combination of various parts in which each part performs a different function. All these parts work together to convert chemical energy of fuel into mechanical energy. Different part of an engine works in different operating conditions. That’s why every part is made by different material. These materials decide its performance and the maximum operating condition i.e. temperature, pressure etc.
Different manufacturer uses different materials for every part to make their engine unique. Beside that, an engine consist some parent materials which can’t be replaced by any other material.
This article provide a list of all those engine material used in automobile industries. I hope you would like it.
|S. No.||Part||Material||Manufacturing Process||Remarks|
High Grade Cast Iron, Aluminum alloy
Under high pressure and temperature, Made in Single Unit
High Grade Cast Iron,Aluminum alloy
Casting or Metal Forming
Upper Part of Cylinder Block Made in Single Unit
Steel alloy, Spheroidal Cast iron, Nickel alloy
Under high fatigue load, that’s why made by forging.
Fine Grain Cast Iron,
Required lower coefficient of friction
Alloy Steel, Nickel steel, Chrome Steel, Chrome Vanadium Steel,Aluminum
Connect Crank Shaft to Piston
Aluminum Alloy, Cast Iron alloy
