减少城市的空气污染现在已是各方面十分关注的问题,构成空气污染的来源是多方面的,其中机动车排放污染愈来愈成为重点。“绿色汽车”的早日实现,不仅是重要的也是迫切的课题,现将国外在这方面的实践和研究进展简介几种方案。 1.机电混合(动力)轿车和单车 机电混合汽车是充分利用内燃机的最佳工况辅以电机,巧妙地利用它的灵活性,适时地添加动力,或者即时储能,以不浪费一滴油为目的,把能耗指标大幅度地降低,超出现行高效节能汽车的效率一倍以上,达到每公升能走30～35km的节能效果。
Reducing urban air pollution is now a matter of great concern to all parties. There are many sources of air pollution, of which pollution from motor vehicle emissions is becoming a more and more important issue. The early realization of the “green car” is not only an important and urgent issue, but also introduces several programs abroad in the field of practice and research progress. 1. Electromechanical hybrid (powered) sedan and cycling Electromechanical hybrid is to take full advantage of the best working conditions of the internal combustion engine with motor, skillfully use its flexibility, timely add power, or instant energy storage, in order not to waste a drop of oil is Purpose, the energy consumption index significantly reduced, more than double the efficiency of existing energy-efficient cars, reaching 30 ~ 35km per liter of energy-saving effect.
