摘要
使用AVL4000型五气分析仪连续测量了492QBW车用汽油机在多种稳定工况下排气中有害成分CO,HC和NO的量。并且运用灰色关联理论对汽油机排放性能试验结果进行了处理和分析,结果显示,发动机的转速对汽油机的CO,HC排放关联度最高,而扭矩对NO排放的关联度最大。
The harmful exhaust emissions CO, HC, and NO of a 492QBW petrol engine are continually tested on several working conditions. The experimental results on the stable working conditions are analysed by the theory of grey relation. The analysis shows that the engine speed has the greatest relation with the exhaust emissions CO, HC while the torque has the greatest relation with the exhaust emissions NOx.
