Abstract:
An improved apparatus controls negative pressure in a combustion engine. The apparatus has a brake booster that is capable of increasing braking force of a vehicle by means of the negative pressure in the brake booster. A valve disposed in an air intake pressure generates the negative pressure that is supplied to the brake booster. An electric control unit controls the valve when pressure in the brake booster is in excess of a predetermined magnitude.
