摘　　要：分析和研究了在用轿车电控发动机在稳定工况下出现不正常怠速抖动的原因,指出部分使用因素诱发发动机的个别气缸做功行程时的气体作用力Ｐg 过小,导致发动机总扭矩Ｍ∑的不均匀性提高,曲轴回转不均匀性增加,以致引起冲击、振动。并提出解决问题的思路和方法。Abstract: The electronic control engine of in-use cars was analyzed and studied to find out the abnormal idlevibrating reasons in stable working modes. It was presented that some practical factors induce that the gas acting pres-sure Pg in cylinder of the engine becomes too low in acting flight, which causes the uneven increase of gross momentof torque M∑of the engine and the crankshaft rotating, and further leads to impacts and vibrations. The ideas andmethods to settle the problem were offered.
