Brief analysis of automobile energy-saving technology paper

1. Gasoline engines are widely used in current vehicles, but compared with diesel engines, they are far inferior to diesel engines in terms of combustion efficiency, so they are not as good as diesel engines in terms of energy saving. Therefore, diesel engines can be used in future passenger cars. It is the first choice for engines and a key point in the study of energy-saving technology.

2. The key to energy saving in automobiles is the technology of internal combustion engines. In terms of energy-saving technology of internal combustion engines, should be discussed from these aspects: the first is gasoline engine direct injection technology, thin and layered combustion technology; the second is the high-pressure injection technology of diesel engines; the third is the multiple injection technology of diesel engines; the fourth is the variable valve technology; and the fifth is the exhaust gas turbocharging technology.

3. Cars are operated by fuel, and the level of fuel consumption is closely related to the level of the driver. Therefore, when driving, you must ensure that the technology is in place and the habits are correct.

4. Research and development and use of automobile energy-saving and emission reduction technology to improve the comprehensive performance of the engine from the four aspects of fuel electronic control injection technology of gasoline engine, thin combustion technology, optimized design of combustion system, and closed-loop control system of electric injection engine.

5. Automobile fuel-saving technology With the increasing shortage of energy and the increasing urgency of environmental protection, the energy conservation work is more in-depth;At the same time, due to the improvement of the demand for economic benefits in industrial production, as a direct and effective measure to reduce operation costs, energy-saving work should also be further improved.
