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.
摘要翻译：在发动机启动时，控制点火正时和空燃比，以防止过载到ISC空气的体积上，减小转矩和转矩差。确定基于在怠速期间抑制旋转波动的点火正时校正量的燃料条件，并且校正基于结果的燃料量。在发动机起动之后，直到在催化剂的热点产生引燃燃烧器之后，主要执行点火延迟控制，并且在确定在催化剂的热点中产生引燃燃烧器时，要执行稀空燃比控制而不是点火延迟控制。此外，当点燃延迟控制变为稀薄空燃比控制时，沿着等效的ISC空气量线执行状态转换控制，以便不引起转矩波动。
