1.Through a group of transient AFR tests on a EQ491i engine,this paper analyzed the factors which cause AFR excursion in transient and studied the effect of the modification terms on transient AFR excursion.
在发动机台架上对EQ491i电控汽油喷射发动机的加、减载瞬态过程的空燃比进行了测量 ,对引起瞬态过程空燃比变化的原因进行了分析 ,并通过试验研究了相应的修正控制项对空燃比的影响。
2.This paper presents the results of rock magnetism studies of 244 directed samples collected from Yangmeishan section in Xiushui County,Jiangxi Province. Several geomagnetic polarity reversals can be identified in Yangmeishan section, which, in their top?down order, are Blake reverse polarity excursion, Emperor reverse polarity excursion, the boundary of Brunhes?Matuyama polarity zone and the Upper Jaramillo normal subzone.

9.But during fuel control process the Air-Fuel-Ratio (AFR) shows an excursion,resulting in a low conversion efficiency of TWC because of the inexact control whichmaybe on account of the engine consistency and aging.
但是在发动机燃油控制过程中,由于发动机一致性以及由发动机老化带来的燃油控制精确性问题,空燃比偏离化学计量比,使TWC转化率下降,导致排放大量增加。
