Air-fuel ratio control device of internal combustion engine for vehicle
专利汇可以提供Air-fuel ratio control device of internal combustion engine for vehicle专利检索，专利查询，专利分析的服务。并且PURPOSE: To augment the output only when the power performance is required by prohibiting the output augmentation in the operation area where the operation with the output air-fuel ratio is not required at the preset opening or above of a throttle valve, and controlling a switching means for the operation with the base air-fuel ratio.
CONSTITUTION: A base air-fuel ratio setting means B sets the base air-fuel ratio, and an output air-fuel ratio setting means C sets the output air-fuel ratio (air-fuel ratio on the richer side than the base air-fuel ratio). A throttle valve wide opening detecting means E detects the preset opening or above of a throttle valve and generates a signal to a switching means D to select the setting means C. The change state of a car speed detected by a car speed detecting means F is calculated by a car speed change state calculating means G, and the area where the output air-fuel ratio control is not required is judged by an output air-fuel ratio control unnecessary area judging means H based on the change state. A control means I prohibits the switching to the setting means C by the switching means D in this unnecessary area, and an air-fuel ration control means A operates an engine with the air-fuel ratio set by the setting means B.
