ABSTRACT:
An improved apparatus for controlling fuel injection in an internal combustion engine is disclosed. The engine performs stratified charge combustion. A throttle valve causes negative pressure to be produced in the intake duct. A brake booster is operated by the negative pressure in the intake duct to increase the braking force. When the value of the negative pressure applied to the brake booster is inadequate, an ECU decreases the opening of the throttle valve to increase the negative pressure in the intake duct. The ECU controls the injection valve to increase amount of fuel injected from the injection valve in accordance with the decrease of the opening of the throttle valve for maintaining the engine speed.
