摘要： An engine idling control device includes a secondary air supply device, an intake gauge pressure detecting unit and a secondary air supply control unit. The secondary air supply device is disposed on a bypass intake passage communicating with an intake pipe and bypassing a throttle valve. The intake gauge pressure detecting unit detects an intake gauge pressure on the intake pipe side. The secondary air supply control unit controls the secondary air supply device so as to open and close the bypass intake passage when an engine is in an idling state. The secondary air supply device is controlled to obtain the optional opening value. The secondary air supply control unit controls such that the secondary air supply device increases the opening value when the intake gauge pressure becomes higher than a predetermined low load condition in an idling state.

摘要： A catalyst temperature estimating apparatus is provided, capable of estimating the temperature of the catalyst installed in an internal combustion engine on a vehicle by providing various catalyst temperature estimating parameters, when the internal combustion engine is in an idle stop. When it is determined that the internal combustion engine is stopped by determining whether the internal combustion engine is stopped, the temperature of the catalyst is estimated based on temperature coefficients during the engine stop. Estimation of the catalyst temperature even when the engine is in an idle stop makes it possible to accurately and promptly estimate the catalyst temperature when the engine is restarted from the idle stop.
