Magnesium alloy die castings can be popularized in the light weight of automobiles?

Lightweight and intelligent vehicles have become a new trend in global automotive industry technology development. In recent years, with the pressure and development trend of global energy conservation and emission reduction, various countries have formulated strict regulations on the fuel consumption of passenger vehicles, which imposes more stringent requirements on the fuel consumption of passenger vehicles and the corresponding CO2 emissions. It is the development trend of the world automobile. Especially in China, by 2020, the decline in vehicle fuel consumption is significantly greater than in other countries. The pressure on fuel discharge is even greater. Reducing the weight of a vehicle's vehicle is the most effective way to reduce vehicle weight. Lightweight car is to "slim down" the car, and on the basis of ensuring stable performance, energy-saving design of various parts and components, and continuous optimization of models. Experiments have shown that if the vehicle's vehicle weight is reduced by 10%, fuel efficiency can be increased by 6% - 8%; vehicle weight is reduced by 1%, fuel consumption can be reduced by 0.7%; every 100 kg of vehicle conditioning weight, 100 km fuel consumption can be reduced by 0.3 - - 0.6 liters.
