1. The selection of materials for engine and transmission system components includes a considerable number of parts. Among them, there are a large number of gears and various shafts, as well as parts that work at high temperatures, such as intake and exhaust valves, pistons, etc. Their materials are relatively important and are generally selected based on usage experience. The selection of materials for engines and transmission systems varies for different types of cars and production plants. Suitable materials should be selected through extensive calculations and experiments based on the specific working conditions and actual failure modes of the parts.
2. With the increasing shortage of energy and raw material supply, people's demand for energy conservation and consumption reduction in automobiles is becoming higher and higher. Reducing self weight can improve the weight utilization coefficient of a car, reduce material and fuel consumption, which is of great significance in terms of resource and energy conservation and economic value. The materials used to reduce self weight should be lighter and ensure business performance compared to traditional materials. For example, using aluminum alloy or magnesium alloy instead of cast iron can reduce the weight to 1/3 to 1/4 of the original, but it does not affect its performance; Using a new type of duplex steel sheet instead of ordinary low-carbon steel sheet to produce automotive stamping parts, thinner sheets can be used to reduce weight without compromising the strength of the components; Using plastic or fiber-reinforced composite materials instead of steel in the body and some less important structural components can also reduce weight and energy consumption.
