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： 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.

摘要： An engine decompression system that can secure a projecting height of a decompression cam from a base face of a valve operating cam to be relatively large in an engine starting rotational region, and maintain a state in which the projection height is decreased in a complete combustion rotational region of the engine. The decompression system includes a decompression cam shaft provided on a valve operating cam shaft or a rotating member integrally coupled thereto, the decompression cam shaft being capable of rotating between an operating position in which a decompression cam projects above a base face of a valve operating cam to slightly open engine valves during a compression stroke and a release position in which the decompression cam is withdrawn to allow the engine valves to close. A centrifugal mechanism connected to the decompression cam shaft maintains the decompression cam shaft at an operating position in a starting rotational region, and rotates the decompression cam shaft to the release position in a normal running region. The centrifugal mechanism is arranged so that, in a complete combustion rotational region between the starting rotational region and the normal running region, the decompression cam shaft is maintained at a middle position at which the projection height of the decompression cam is less than the projection height at the operating position. The centrifugal mechanism comprises two weights and a return spring to allow at least three equilibrium positions of the decompression system corresponding to the operating, middle and released position.
