The small gasoline engine block has two kinds of materials, aluminum alloy and stainless steel. Which of these two kinds of gasoline engine block is better?
First of all, the two kinds of small gasoline engine cylinder body have the advantages and disadvantages, the stainless steel more strong, the aluminum alloy cylinder lighter, this depends on the locomotive or the working machine, if the motorcycle and the like, the aluminum alloy is better, reduce the weight of the engine, can save oil. The cast aluminum cylinder can reduce the weight of the engine. Like a medicine machine and so on, the choice of stainless steel is better, sturdy and durable.
The physical properties of iron and aluminum are different. Cast iron has stronger heat load capacity, and the potential of cast iron is greater in terms of engine power. For example, the output power of a 1.3 liter displacement cast iron engine can exceed 70kW, while the output power of a cast aluminum engine can only reach 60kW. It is understood that the 1.5 liter cast iron engine can meet the power requirements of the 2 liter engine through turbocharging and other technologies, while the cast aluminum cylinder engine is difficult to meet this requirement.
Aluminum cylinder body part of the engine still uses cast iron materials, especially cylinders, to use cast iron materials. The thermal expansion rate of cast aluminum and cast iron is not uniform after fuel combustion, which is the common problem of deformation consistency. This is a difficult problem for cast aluminum cylinder in casting process. When the engine is working, the engine of the cast aluminum cylinder equipped with cast iron cylinder must meet the sealing requirements. How to solve this problem is a particular concern for aluminum casting cylinder enterprises.
