Question:

Is the engine good or is it good?

Is the engine good or is it good?

Answer:

In addition to the weight difference, there are many differences between the cast iron cylinder and the cast aluminum cylinder in the production process. The cast iron production line covers a large area, has great pollution to the environment and complex processing technology. But the production characteristics of the cast aluminum cylinder block are just the opposite. From the point of view of market competition, cast aluminum cylinder has certain advantages.
From the point of view of the use, the advantages of the cast aluminum cylinder are light weight and fuel saving by reducing weight. In an engine of equal displacement, the use of an aluminum cylinder engine reduces the weight by about 20 kilograms. With a reduction of 10% of the car's own weight, fuel consumption can be reduced by 6% to 8%. According to the latest information, foreign auto weight has been reduced by 20% to 26% compared with the past. For example, Fawkes used a full aluminum alloy material, reducing the weight of the body, while also enhancing the engine cooling effect, improve the efficiency of the engine, and longer life. From the point of view of oil saving, the advantages of the cast aluminum engine in fuel saving have attracted much attention
Advantage of aluminum: at present, the cylinder block of gasoline engine is divided into two kinds: cast iron and cast aluminium. In diesel engines, cast iron cylinders account for most of them. In recent years, with the rapid development of the automobile industry, the car has quickly entered the lives of ordinary people. At the same time, the fuel saving performance of vehicles has gradually been paid attention to. Reducing the weight of an engine will save fuel. The cast aluminum cylinder can reduce the weight of the engine.
For cost reasons, the cylinder body is designed to be much more late than the cylinder head for full aluminum design. The cylinder block is the heaviest part of the engine, therefore, the use of aluminum alloy material can reduce the weight of the engine, thereby reducing the weight of the whole vehicle. This is especially valuable for the front car. However, as we all know, the material changes require more cost expenditure, because of the material prices and processing technology of different, the use of aluminum alloy cylinder engine will naturally be higher than the price of a cast iron engine. In this appeal point, it is clear that the engine of the cast iron cylinder is dominant.
