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 and the fuel injection amount is corrected based on the estimated alcohol rate, thereby determining the fuel injection amount appropriately in accordance with the estimated alcohol rate.

摘要： A carburetor electronic control system includes: transmission devices coupled to valves for opening and closing an intake path of a carburetor; electric motors that make the valves open and close via the transmission devices; and an electronic control unit for controlling the operation of the electric motors. The interior of a casing joined to one side face of the carburetor is divided by a partition plate into a transmission chamber on the carburetor side and a drive chamber on the opposite side. The transmission devices and the electric motors are housed and held in the transmission chamber and the drive chamber, respectively. Therefore, the transmission devices, the electric actuators, and the electronic control unit can be housed in a common casing, thereby reducing the dimensions of the carburetor electronic control system.

摘要： In an engine speed control system for a snow remover, the engine speed is controlled at the desired speed by driving the throttle valve with an electric motor, the engine output power corresponding to the load acting on the snow removal mechanism or travel mechanism is estimated based on the throttle position and the engine speed, and the desired speed is increased in stepwise fashion to a higher value when the estimated engine output power exceeds first through third ascending threshold values. With this, the engine speed maintained when a small load is acting on the snow removal mechanism or travel mechanism can be set to a lower value, whereby the noise level can be reduced and fuel efficiency improved compared with the prior art wherein a mechanical governor is used to adjust the engine speed.
