近年来,我国汽车发动机的质量及可靠性取得了较大的进步,但是发动机的节能减排技术远低于国外先进水平,平均油耗高于国外发动机10%以上,现阶段,虽然我国各企业陆续开展了汽油机节能减排技术的研究和开发,但可变进气系统和喷油系统、增压系统仍是我国汽油机技术的主要瓶颈,需要有所突破。德来特公司为改善目前的现状,加强发动机节能技术的研究,多次开展产学研合作,并 In recent years, great progress has been made in the quality and reliability of automobile engines in our country. However, the energy-saving and emission-reduction technologies of engines are well below the advanced levels in foreign countries and the average fuel consumption is over 10% of that of foreign engines. At this stage, Gasoline engine energy saving and emission reduction technology research and development, but variable intake system and fuel injection system, turbocharger system is still the main bottleneck of China’s gasoline engine technology, the need for a breakthrough. In order to improve the current status quo and strengthen the research on energy-saving technology of engine, Delitech repeatedly cooperates with industry, universities and research institutes
