| 摘 要： | 在1台四冲程、水冷、125mL、电喷火花点燃式摩托车发动机进行燃用LPG燃料的试验,分析空燃比和点火提前角对LPG电喷发动机排放HC、CO和NOx的影响。试验结果表明,在浓混合气条件下,点火提前角对LPG发动机排放的影响较小;但在稀混合气条件下,点火提前角对LPG发动机的排放影响较大。

| Abstract: | Effects of air-fuel ratio and ignition timing on the emissions HC, CO and NOx of LPG EFI engine is presented. Experiments were carried out in a four-stroke, water-cooled, 125mL motorcycle SI engine fueled with LPG. Test results show that on the condition of rich burn, ignition timing has less effect on the emissions, while on the condition of lean burn, ignition has more effect on the emissions. |
