摘    要:对于电控汽油机动力加浓工况,提出了一种基于排气温度的空燃比反馈控制策略。发动机台架模拟试验表明,这种控制策略不但能有效降低燃油消耗率,减少CO排放量,实现三元催化转化器的主动保护,而且也能使空燃比、排气温度、汽车的运行工况和气候条件等达到最佳匹配。

关 键 词:电控汽油机  动力加浓  排气温度  空燃比  控制策略

Abstract:For power enrichment mode of electronic controlled gasoline engine,a new α closed-loop controlled strategy is presented on the base of exhaust temperature.The engine simulative testing shows that the new controlled strategy can effectively depress the fuel consumption,reduce CO emissions,make active protection to TWC(three-way catalysts)and obtain best matching of air-fuel ratio、exhaust temperature、operating mode of car and climate-factor.
Keywords:electronic controlled gasoline engine  power enrichment  exhaust temperature  air-fuel ratio  controlled strategy
