专利汇可以提供Controlling system of air-fuel ratio of automobile engine专利检索,专利查询,专利分析的服务。并且PURPOSE:To ensure an appropriate controlled state, by suspending the intake of a learned value from an O2 sensor until a prescribed time elapses after the reduction of fuel, to prevent the irregularity of the learned value for air fuel ratio control. CONSTITUTION:In a step 2, the rotational frequency of an engine is taken into a table. In a step 4, the load on the engine is taken into a table. When it is judged in a step 6 that fuel is not reduced, a learned value is compensated by a feedbacksignal from an O2 sensor. If it is judged in the step 6 tha the fuel is reduced, a step 8 is taken to set a delay timer to temporarily suspend the intake of the leaned value. The irregularity of the learned value for air fuel ratio control is thus prevented to ensure an appropriate controlled state.,下面是Controlling system of air-fuel ratio of automobile engine专利的具体信息内容。
