Every major auto show will have auto manufacturers exhibit their own energy-saving and environmentally-friendly technologies. They not only meet more stringent emission regulations, but also bring benefits to consumers - energy saving means saving fuel and money. So what technologies are currently used in automobiles to achieve energy saving and environmental protection? I’ll take a look at it for everyone today.
â– Traditional power:
(1) Gasoline engine efficiency improvement - supercharging and self-priming go hand in hand
What new engine is the hottest? That is still a small displacement turbocharged engine, especially a gasoline engine. Through the evolution of technology, the turbo lag is greatly weakened, which not only helps the driving experience to improve, but also improves the economy - the engine will work earlier and work faster in the economic range. In the small-displacement supercharged engine, the domestic consumers are more likely to buy European and American models.
Of course, natural inhalation is by no means an article that can be done. In this regard, Japanese manufacturers have set an example. Honda has its own "Earth Dream Technology" series of engines, of which 1.5-liter direct-injection, 2.4-liter direct-injection engine has brought us a very good feeling on domestic models; and Toyota is preparing to popularize VVT ​​on more engines. - iW variable timing and D-4S dual injection two new technologies - from 2.0 liters four cylinders to 3.5 liters V6, up to 5.0 liters V8 engine, covering all models.
(2) Transmission system upgrade - efficient and at the same time driving experience
With a good engine, no good transmission is like a person with one leg missing. Similar to the engine, the transmission system goes hand in hand. In addition to the simple and efficient manual transmission, the automatic transmission also uses multiple technical methods such as DCT, AT, CVT, etc., from the driving quality and economic improvement, it is even more powerful for these new engines. effect.
(3) Diesel engine is cleaner - reducing particulate emissions
Although diesel engines have not been widely used in the Chinese passenger car market, it is undeniable that the economics and carbon emissions of new diesel engines after the recovery of particulate matter are remarkable - this is also the reason why diesel engines are in the European market, including various luxury. Almost all models listed in Europe, including the brand, will have a diesel version.
â– Tires also contribute to the popularity of low-roll resistance energy-saving tires
In addition to improving the efficiency of the engine and transmission system, reducing the resistance of the vehicle is also an important energy saving measure. On the one hand, the wind resistance of the vehicle should be reduced, and the rolling resistance of the car needs to be smaller, so that the energy-saving tires come in handy. The major tire brands have their own low-rolling tires, not only equipped with new energy vehicles, but also ordinary vehicles. Widely equipped.
Taken together, traditional automotive technology still has room for improvement, and there are advantages in terms of technology maturity and cost. This is why automakers still focus on this.
