00铁发动机与铝发动机的区别（The difference between an iron engine and an aluminium engine）

00铁发动机与铝发动机的区别（The difference between an iron engine and an aluminium engine） The difference between an iron engine and an aluminium engine In the case of the engine material, people often talk about the main cylinder and cylinder cover, such as the regular all-aluminum engine, which means the cylinder and the cylinder cover are made of aluminum alloy. Todays engine, the cylinder head is not aluminum alloy already very few, so cylinder cover we wont discuss. Tell me about the cylinder. Just now, the whole aluminum engine cylinder body is made of aluminum alloy, not all right. Most all-aluminum engines also use cast iron liners. 1) weight Aluminum is lighter than cast iron, and the aluminum cylinder is much lighter than the requirement of intensity. The engine is light and can have a positive impact on the weight distribution of the vehicle, and the vehicle quality is also lighter. So, this is an aluminum cylinder. 2) volume For the same reason, aluminum has a light weight, and the aluminum structure of the unit volume is smaller than that of cast iron, so the aluminum cylinder usually has a larger volume. The cast iron cylinder is dominant in this point. 3) corrosion resistance and strength Aluminum is easy to produce and the water produced when it burns produces chemical action. It is less corrosive than cast iron cylinder body, especially the supercharged engine with higher temperature and pressure. And the previous side of the volume, in turn, says that when your engine size requires less than an hour, its usually hard to get the strength of the cast iron cylinder. So many of the supercharged engines are made of cast iron cylinders, which are generally not very easy to use. The cast iron cylinder is dominant in this point. 4) cost Cost nature is aluminium cylinder body is expensive, have nothing to explain. The cast iron cylinder is dominant in this point. Resistance to detonation Aluminum heat faster, so the cooling performance is good, can help to reduce the pr
