Cylinder block must come with enough strength and good casting and cutting, and the price is lower, so the cylinder block material is cast iron, alloy cast iron. Aluminum alloy cylinder body using more and more common, because the aluminium alloy cylinder light weight, good thermal conductivity, coolant capacity can be reduced. After the cylinder up to temperature quickly and exactly the same coefficient of thermal expansion of aluminium piston, heated space small, impact noise, and engine oil consumption can be reduced. And same as thermal expansion of aluminum alloy cylinder head, hot and cold shock resulting from thermal stress can be reduced.
