What are the main methods of automobile energy saving?

1, strengthen national legislation;

2, national tax policy tilted toward small-displacement cars;

3, the development and utilization of new fuels;

4, improve engine performance (direct injection technology, variable valve lift and timing technology, variable cross-section turbocharger technology, and other technologies);

5, the development of automotive lightweight technology ;

6, giving priority to the development of public **** transportation; 7 improve the business level of drivers. Solid suspended particles can be harmful to human health. Because it has a strong adsorption capacity, it will bring various harmful substances into the human respiratory tract, lungs and so on.

Expanded Information:

The type of engine determines the approximate range of effective fuel consumption rates, and the order of thermal efficiency from low to high is: two-stroke engine, four-stroke gasoline engine, two-stroke diesel engine, and four-stroke diesel engine. Vehicle energy efficiency is the reduction in fuel or stored energy consumption of a vehicle for the same transportation task (volume or turnover). 1/4 of the world's energy is used for transportation, including 2/3 of the oil produced annually.

Some energy-saving measures in transportation don't cost anything at all, for example: keeping tires properly inflated improves energy efficiency by 6%. In addition, environmentally friendly vehicles such as hybrids can get up to 20% more mileage than conventional cars while consuming the same amount of gasoline. Energy is the material basis for human survival and development. With the rapid development of the automobile industry, the issue of energy saving and emission reduction has been a growing concern.
