摘要： A fuel injection control system corrects the amount of fuel injected by fuel injection valves toward an increased side when an acceleration state resulting from operation of a throttle occurs. An acceleration state determiner determines that a state is an acceleration state based on a change in throttle valve opening degree, and inputs a signal inducing fuel-amount-increase correction to an acceleration corrector. When a considerable change in the throttle valve opening degree occurs a predetermined number of times or more before a certain time period expires, determination of the acceleration state is stopped until a predetermined time period elapses.

摘要： A choke valve is controlled finely suited to the running state of an engine. A throttle valve (8) and a choke valve (9) are provided in series on an intake pipe (6), and the opening degree of the choke valve (9) is controlled by a stepping motor. The choke valve opening degree upon start of engine (start opening degree) is determined depending on the engine temperature. The stepping motor (11) is initialized at the fully closed side of the choke valve (9) when the power source for starting the engine is turned on. The start opening degree of the choke valve is judged to be closer to the fully closed side or fully opened side, and the stepping motor (11) is initialized at the fully closed side if judged to be close to the fully closed side, and at the fully opened side if at the fully opened side.

摘要： In an apparatus for controlling an air/fuel ratio of a general-purpose internal combustion engine using mixed fuel containing alcohol and gasoline and operated at a desired engine speed inputted by the operator while a throttle opening is regulated such that a detected engine speed converges to the inputted desired engine speed, a fuel injection amount prepared for mixed fuel is increased/decreased when a load is kept constant and the output air/fuel ratio (at which an output of the engine becomes maximum) is estimated. A rate of alcohol contained in the fuel is estimated from the estimated air/fuel ratio (S300 - S308, S312, S316 - S320, S324, S326) and the fuel injection amount is corrected based on the estimated alcohol rate (S310, S314, S322, S328), thereby determining the fuel injection amount appropriately in accordance with the estimated alcohol rate.
