What Is A Car Engine Made Of?

1. Cylinder block: The cylinder block is the most basic part of the engine, and all other parts are directly or indirectly installed on it.

Cylinder block material is divided into two kinds, one is cast iron, generally use gray cast iron casting, now the engine in order to enhance the cylinder block strength and wear resistance, but also used high quality gray cast iron containing nickel, chromium, molybdenum, phosphorus and other elements. Some high - strength diesels will be made of higher grade ductile or vermicular cast iron. Cast iron cylinder block strength, stiffness, wear resistance and vibration absorption capacity are very excellent, the biggest disadvantage is the weight.

And now the gasoline engine used in small cars, more use of aluminum cylinder block, or aluminum alloy cylinder block. They use aluminum alloy or aluminum magnesium alloy cast, the biggest advantage is light weight, good heat dissipation, but the strength, stiffness, wear resistance and vibration absorption capacity of the cylinder block is not as good as cast iron. So put to rest the Internet trolls who boast that aluminum engines are better.

2, cylinder head: cylinder head and cylinder block working conditions and structural complexity have many things in common, so the two generally use the same material casting, is also gray cast iron or alloy cast iron. In order to improve the heat dissipation performance and reduce the weight of the engine, aluminum alloy will be used to cast the cylinder head. But aluminum alloy strength is low, easy to deformation in use, can only be used in gasoline machine, diesel engine or use higher strength cast iron.
