Abstract
A fuel injection quantity control device for use with a two cycle engine being rotatably driven by receiving a fuel-air mixture injected into the engine based on fuel injection quantity instruction signals and the air supplied through an intake passage and ignition of the fuel-air mixture in a combustion chamber includes a rotational speed Ne detection device for detecting the rotational speed Ne of the two cycle engine and for generating a rotational speed Ne signal. An opening .THETA. detection device is provided for detecting the opening .THETA. of a throttle provided in an intake passage for regulating the supply of air and for generating an opening .THETA. signal. A basic injection quantity setting device is provided for setting a basis injection quantity of the fuel based on the rotational speed, Ne signal and the opening .THETA. signal. A fuel-air mixture condition judging device judges the conditions of the fuel-air mixture and an injection quantity instruction signal generating device corrects the basic injection quantity to reduce the quantity in response to misfire in said fuel-air mixture for changing the conditions of the fuel-air mixture to ignition, and outputs the corrected basic injection quantity as an injection quantity instruction signal the fuel-air mixture condition judging device judges a misfire at the present time based on a misfire in the past.
