The automobile industry is an important industry in the development of the national economy, and it is also the second largest industry in the world's carbon emissions. The energy saving and emission reduction of automobiles is to alleviate environmental problems and is the key to achieve sustainable and healthy development.

At present, the measures taken by the automobile industry to solve the problems of energy conservation and environmental protection are reflected in two aspects: one is to vigorously develop new energy vehicles represented by electric vehicles and hybrid vehicles; the other is to achieve lightweight vehicle quality.

What is New Energy?

New energy vehicles refer to vehicles that adopt new power systems and are driven entirely or mainly by new energy sources. The new energy vehicles referred to in the plan mainly include pure electric vehicles, plug-in hybrid vehicles and fuel cell vehicles.

The significance of automobile lightweight to the development of modern automobile

① Lightweight cars can effectively save fuel consumption and reduce emissions.

Lightweight is the most effective measure to achieve energy saving and emission reduction, and it is a necessary trend for the automobile industry to pursue healthy and sustainable development. Data show that for every 10% reduction in the overall quality of the car, fuel consumption can be reduced by 6% to 8%, and CO2 emissions in the atmosphere are also reduced. On the basis of the research and development of traditional fuel vehicle lightweight technology, the lightweight of new energy vehicles can improve the power performance. The use of lightweight materials is the most mature lightweight method at this stage. Aluminum-magnesium alloy and carbon fiber reinforced composite materials have been applied. It is expected that it will be more used in new energy vehicles in the future.

 

② Lightweight cars can improve the driving performance and safety performance of cars.

Lightweight cars can improve the driving performance and safety performance of cars, reduce the quality of cars, and improve the driving performance of cars. According to the American Aluminum Association, every 25% reduction in car weight can reduce the time for cars to accelerate to 96. 56 km h- 1 from the original 10 s to 6 s; Reduce the mass of cars, and at the same time reduce the load of power and power transmission system, it can make the car show the same or better performance under lower traction load.

 

Application of Aluminum Alloy in Automobile

The lightweight of the car refers to the reduction of the curb weight under the premise of ensuring the safety of the car's performance.Aluminum alloy itself has good corrosion resistance, weldability, easy forming and thermal conductivity. The key is that aluminum alloy is easy to recycle.

At present, aluminum alloys are used in engines, heat exchangers, wheels and other components, which can achieve a good weight reduction effect. Aluminum alloy is currently the most widely used and most mature light metal materials.

In recent years, the use of aluminum alloy in automobiles has been increasing. David Scholes, an American senior automotive engineer, predicted the development of aluminum alloy for automobiles:In the future, aluminum alloy may be applied to every part of the car, and the quality may be lighter than plastic.. At present, a large part of the body parts are made of aluminum, such as the engine, heat exchanger, wheels and body, etc., aluminum alloy with its own characteristics to make the parts achieve a good weight reduction effect.

The automobile industry in Europe and the United States is very developed, and it has long begun to pay attention to the energy saving and emission reduction of automobiles and the important role of aluminum alloy in automobile lightweight.

There is no doubt that the development of lightweight automotive materials is the inevitable trend of automotive lightweight, with the energy crisis and environmental pollution problems are becoming more and more serious, the research of automotive lightweight will become a hot issue, and aluminum alloy materials with its advantages will play a more important role in the research of automotive lightweight process.
