Abstract
An air-fuel ratio control system for a two-cycle engine is disclosed, which includes a cylinder, a crank case serving also as a pressure chamber, a fuel injection unit including an injector and a pump, an engine speed detecting element for detecting the engine speed, and a throttle opening degree detecting element for detecting the opening degree of a throttle valve. The control system is constructed of a crank case temperature detecting element for detecting the temperature of the crank case; a first setting element for setting an increment correction coefficient for increasing a fuel injection quantity, in accordance with the temperature of the crank case detected by the crank case temperature detecting element; a second setting element for setting a basic fuel injection quantity in response to the engine speed and throttle opening degree detected by the engine speed and throttle opening degree detecting element; and a third setting element for setting a fuel injection quantity by correcting the basic fuel injection quantity set by the second setting element in accordance with the increment correction coefficient set by the first setting element.
