Abstract

PURPOSE:To prevent excessive concentration of mixture gas of a small cylinder engine by detecting a low-rotation high-load with a load sensor and a rotation frequency detector circuit of an engine thereby shortening basic injection time pulses. CONSTITUTION:In a basic injection amount setting apparatus 1, a basic injection amount is calculated by dividing intake air amount Qa by rotation frequency N. An overall injection amount is determined by multiplying the correction factor of an increase amount correction setting apparatus 2 by an overall injection amount setting apparatus 3. The output 6a of the load sensor connects with the basic injection amount setting apparatus 1 and the correction setting apparatus 2. The basic injection time pulse at low-rotation high-load is shortened by the setting apparatus 1. By this construction, the excessive concentration of mixture gas of small size engine cylinder is prevented at a low-rotation high-load.
