摘　　要：研究了天然气汽车的动力性能与排放性能,对改装的492QC天然气发动机和原发动机(燃用汽油)的扭矩、功率等进行了测量.实验结果表明:当由燃烧汽油变换为燃烧天然气时,发动机的扭矩、功率下降非常大;增大点火提前角可使发动机的动力性能得到改善,但发动机NOx,总碳氢THC,CO及CO2的排放污染明显减少.The power performance and exhaust emission of natural gas vehicle are studied. The power and torque of modified 492QC natural gas engine and 492QC gasoline engine are measured. The results indicate that the power and torque of the engine is considerablly decrease from buring natural gas to 492QC compression natural gas. When increasing the spark advance angle, the engine performance is improved, but the exhaust emission of NOx, THC, CO and CO2 are decreased.
