摘 要: 利用高精度的移动排放测试仪,对涡轮增压轿车和非涡轮增压轿车进行深圳典型道路工况下的排放测试,分析涡轮增压技术对轿车排放的影响。测试数据分析表明,涡轮增压轿车的CO,HC和NOx平均排放因子都低于非涡轮增压轿车。这主要得益于更多的O2供应、更高的压缩比和中冷器技术,实现了更加充分的燃烧和更低的热负荷,从而改善了车辆的排放。 With a high-precision mobile exhaust instrument,the emissions of turbocharged and natural aspirated car in Shenzhen typical roads were tested and the influence of turbocharging technology on car emission was analyzed.The test data show that the mean emission factor of CO,NOx and HC from turbocharged car is smaller than that from natural aspirated car.More oxygen,higher compression ratio and intercooling technology reach more complete combustion and lower thermal loads,which improve the vehicle emission.
