Abstract
A fuel injection device for internal combustion engines, provided with a light load fuel injection valve and a heavy load injection valve for each cylinder of the engine. The light load fuel injection valve and the heavy load fuel injection valve are provided in an intake passage. The light load fuel injection valve is positioned close to the combustion chamber of the engine whereas the heavy load fuel injection valve is located further from the combustion chamber than the light load fuel injection valve. The fuel injection device is also provided with a control circuit which controls the light load fuel injection valve to provide additional supply of fuel during engine accelerating operation so that the increased fuel is rapidly introduced into the combustion chamber at the time of engine acceleration.
