Applicable aluminum engine engine cylinder

The cylinder block is the main engine, which will each cylinder and crankcase fused, is to install the supporting skeleton of the piston, crankshaft and other parts and accessories. It has many types, such as Nikasil cylinder, aluminum alloy engine cylinder and so on.
Production of aluminum die-cast cylinder automobile engine, we all know, die-casting products have many products for automotive parts. As for environmental protection, increasing demand for lightweight automotive many key components, such as aluminum alloy engine cylinder, and gradually turned to casting production. Over the years, most of Europe and Japan's auto companies have adopted the method of production of aluminum alloy engine cylinder casting. In China, with the production of aluminum alloy engine cylinder casting method is also becoming a trend. Cast aluminum engine block than half the weight of the engine can be reduced. Originally the total weight of the car is not high, but the proportion of the engine can not be ignored, the most direct effect of weight reduction of fuel consumption performance is enhanced. The weight of the engine is also directly affect vehicle performance, mostly due to the general front-wheel drive sedan, such as cockpit weight is too heavy, it will cause excessive steering the vehicle cornering and braking distance will be longer. Pros: You can half the engine light weight, can effectively reduce fuel consumption and improve handling performance. Cons: expensive aluminum material.

Aspects of engine material, usually people often talk about the main cylinder block and cylinder head material, such as aluminum engines often said, is that aluminum alloy engine cylinder and aluminum engine block.
1) Weight
Under the proportion of aluminum is lighter than cast iron, to meet the strength requirements of the premise, the aluminum cylinder block to light many.
2) volume
For the same reason, the proportion of light aluminum, aluminum structural strength per unit volume is smaller than that of cast iron, but it is the volume of the aluminum cylinder block is generally larger.
3) corrosion resistance and strength
Easy to produce aluminum and water when burned chemical action, less corrosion of cast iron cylinder block, especially for temperature and pressure are higher supercharged engine even more so.
4) Cost
Cost is naturally more expensive aluminum cylinder block, no interpretable.
5) antiknock
Faster thermal conductivity of aluminum, so that good cooling performance, the engine can help to reduce the probability of occurrence of abnormal combustion, the same compression ratio, the lower the aluminum cylinder engine can use the label than the cast iron cylinder gasoline engine.
6) Coefficient of friction
Now the engine, in order to reduce the inertia of the reciprocating parts, improving speed and response speed of the aluminum alloy is often used as the material of the piston.
