How to realize energy conservation and emission reduction in the cars ?
1. Energy-saving in the internal combustion engine
Passenger car whose discharge amount is below 2 liter, especially below 1.6 liter, is encouraged to adopt pressurization and direct injection technology to promote the lightweight technology. in terms of the diesel engine, it should enhance thermal efficiency, and adopt electric-control high pressure fuel injection system, high-efficient pressurized inter-cooling system, exhaust after treatment system, and electronic control technology.
2. Energy saving in heavy truck lightweight
With the fast development of logistics and transportation, truck lightweight has become the major trend of the global truck manufacturing industry. lightweight car materials technology has become the important standard of new truck research and development. The aluminum trailer researched by the Hunan Shengtong Group is 10.5 meters long, 2.55 meters wide, 3.8 meters high. The trailer adopts aluminum materials used in the high-speed rail and aerospace. The trailer has high strength, and the weight reduces 3.4 tons compared with the same kind steel trailer. Within the life cycle, the trailer could save 45,000 liters oil, and the carbon dioxide discharge will reduce 110 tons.
3. Promote the natural gas fuel to realize zero discharge
Compared with the diesel, the use of natural gas could reduce 39496.5 kg pollutants per year. once leaked, the natural gas could diffuse in the air, and has good environmental protection effect.
