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

00铁发动机与铝发动机的区别（00 the difference between an iron engine and an aluminum engine） The difference between the engine and the iron aluminum engine The material of the engine, people usually talk about is mainly to the cylinder block and cylinder head material, such as is often said that the entire aluminum engine, refers to the cylinder block and cylinder head are used Aluminum Alloy casting. The engine cylinder head, not Aluminum Alloy has few, so we will not discuss the head. About the cylinder. Said the entire aluminum engine cylinder is Aluminum Alloy manufacturing, in fact not all right. Most of the aluminum engine to use cast iron cylinder liner. 1) weight Aluminum is lighter than iron, meet the strength requirements of the premise, to light many aluminum cylinder. The engine is light, can the weight distribution of the vehicle to play the positive effects, quality of vehicle light. Therefore, this point of aluminum cylinder dominant. Volume 2) The same reason, the proportion of light aluminum, aluminum structural strength per unit volume is less than the iron, so the aluminum cylinder usually volume instead of some. This point dominated cast cylinder. 3) corrosion resistance and strength Aluminum and easily produced during the combustion of water chemistry, corrosion resistance than the cast cylinder, especially the supercharged engine temperature and pressure are higher especially. But in front of the conclusion about the volume, in turn, when your engine volume is small, the use of aluminum cylinder is hard to achieve the strength of cast iron cylinder. So many of them using high pressure engine cast cylinder, if the use of aluminum cylinder, basically not too easy. This point dominated cast cylinder. 4) cost Cost is naturally expensive aluminum cylinder, what can not explain. This point dominated cast cylinder. 5) antiknock Aluminum heat faster, so the cooling performance is good, can help reduce the probability of occurrence of non normal combustion engine, t
