文档介绍:浅论柴油机技术发展趋势
【摘要】随着世界汽车对汽车发动机动力性、经济性和排放提出了更高要求和计算机技术的迅速发展,柴油机被公认为节能的代表和减少汽车尾气排放污染的有力工具,汽车柴油化也是汽车发动机发展的一大趋势。本文结合当前发展状况,论述了缸内直接喷注技术和柴油化趋势是未来车用发动机的发展方向。
【 pick to 】 as the world car of car engine performance, fuel economy and emissions was put forward higher requirements, and the rapid development puter technology, the diesel engine is recognized as representatives of the energy saving and reduction of car exhaust pollution es a powerful tool, auto Chai Youhua is a trend of development of automobile engine. Combined with the current development situation, this paper discusses the in cylinder direct injection technology and Chai Youhua trend is the development direction of the future vehicle engines.

柴油机的开发焦点已由传统的优先考虑经济性、可靠性和耐久性逐步转为目前的优先考虑环保的要求,即以优先保护好人类赖以生存的地球环境为出发点去考虑采用何种技术,去评价其先进性。
Focus of the development of diesel engine has been developed from traditional give priority to economy, reliability and durability gradually converted to the current priority environmental protection request, namely the priority to protect earth's environment as the starting point to the survival of humans to think about what technologies, to evaluate its advanced nature.
优先考虑柴油机排放、噪声对环境的影响问题,与过去相比也有不同,就是在满足目前对排气污染物、颗粒排放及噪声的限制要求时,不再以牺牲经济性、动力性和比质量等为代价,而是在达到上述目标的同时使产品具有可竞争的商业价格。欧洲一些公司近年或稍后将继续推出能满足环境要求的百公里油耗为3L的柴油机。
Priority diesel engine emission, noise impact on the environment problem, and there are different than in the past, is in meet the current restrictions on exhaust emissions, particle pollutants and noise, not at the expense of the economy, power performance and quality than price, but in achieving the goals at the same time, make our products have a price in petitive business. panies in recent years, or later will continue to launch can meet the environmental requirements of the gas mileage is 3 l diesel engine.
当前和将来一个时期车用柴油机技术的发展趋势突出表现在如下几个方面:
