  • Control system for internal combustion engine
    Patent number: 8485157
    Abstract: A control system for an internal combustion engine having a plurality of cylinders including first and second cylinder groups. The first and second intake systems correspond respectively to the first and second cylinder groups, and first and second throttle valves are provided respectively in the first and second intake systems. An output of the engine is reduced upon deceleration of a vehicle driven by the engine. A pressure parameter indicative of an assisting force generated by a brake booster is detected. An intake negative pressure is supplied to the brake booster from the first and second intake systems. One of the first and second throttle valves is opened to increase the engine output when the pressure parameter is equal to or less than a first threshold value which indicates that the assisting force of the brake booster has decreased.
