摘要： At the start-up of an engine, the ignition timing and the air-fuel ratio are controlled to prevent overload onto the volume of ISC air and decreased torque and torque difference.The fuel condition based on the amount of ignition timing correction to inhibit rotational fluctuation during idling is determined and the fuel quantity based on the result is corrected.Right after an engine has started and until a pilot burner is created in the heat spot of the catalyst, the ignition retard control is mainly executed, and at the time when it is determined that a pilot burner has been created in the catalyst's heat spot, the lean air-fuel ratio control is to be executed instead of the ignition retard control. Furthermore, when the ignition retard control changes to the lean air-fuel ratio control, the state transition control is executed along the equivalent ISC air volume line so as not to cause torque fluctuation.

摘要： The invention precisely achieves an air fuel ratio control precision in each of operating regions of an engine, particularly a demand air fuel ratio at a time of an engine transition. In a fuel control system correcting a basic fuel amount in such a manner as to estimate a fuel adhered to an air intake pipe of an engine and an evaporated fuel from the adhered fuel so as to achieve a demanded air fuel ratio, a temperature of a fuel adhered portion is estimated on the basis of an amount relation between the fuel to be adhered and the already adhered fuel, or a heat quantity balance. A fuel adhesion amount and a fuel evaporation amount are determined on the basis of the estimated temperature.
