Affected by changes in the international economic environment, the investment growth of the world's auto industry in the field of environmental protection has accelerated dramatically in recent years. According to a survey conducted by the California International Automobile Economy Institute in the United States, in the 1980s, the investment in environmental technologies of the automotive industry in North America, Western Europe, and Japan increased by an average annual rate of 5.5%, about 8.5% in the first five years of the 1990s. Between 1996 and 2000, it reached 12.5%, of which Germany reached 15%. In the 21st century corporate development strategy, General Motors decided to strengthen the development of environmentally friendly products and technologies, to develop low-pollution vehicles, and to promote the use of recyclable materials. In addition, the auto industry in South Korea, Brazil and Mexico also attaches great importance to environmental protection technology. The three countries have successfully developed environmentally friendly vehicles as early as five years ago. South Korea’s fuel cell buses have been put into small-batch production, and Mexico has also The United States jointly develops electric vehicles. The main directions of environmental investment are:
Exhaust after-treatment technologies, such as catalytic particulate filters, etc.
Energy-saving technologies, such as 42V power supply technology, common rail injection system, etc.
Development and application of alternative fuels (clean energy) such as natural gas, alcohol, methanol and hydrogen;
Promote hybrid systems that use a combination of fuel engine and electric energy;
The development of vehicle battery-powered systems, including fuel cells and batteries, has made significant progress in hydrogen-based fuel cell technology.
Research on lightweight materials. In the past 10 years, the development trend of the world's car materials has been lightweight and diversified. The consumption of ferrous metals has been reduced, while the consumption of non-ferrous metals, light alloys and non-metallic materials has increased. In addition, plastic modules will be widely used in cars.
