4GE型汽油机三元催化转化试验研究

Research on Three-way Catalytic Experiment of the 4GE Type Gasoline Engine

通过对采用闭环多点电控喷射系统并装用三元催化转化器的4GE型汽油机的试验证明,其排放值完全符合排放法规要求,对噪声影响不大,功率损失很小且对有害物的转化率很高,取得了满意的排放效果。

One closed - loop multi - point electronic controlled fuel injection system and one three - way catalytic converter are applied in a 4GE type gasoline engine. The experimental result proves that the exhaust emissions meet the requirements of the standards, the effect of the fuel injection system on vehicle noise is little, the power loss is very small, and the converting rate of hazardous substance is very high.
