    摘要: Suppresses noise due to high engine speed and improves emission and fuel consumption of a hybrid generator. A difference computing unit 29 computes a first difference between an alternator output and a load output. A difference computing unit 31 computes a second difference between a battery output and the load output. When the battery output is greater than a battery output stopping threshold, the alternator output is fixed and the first difference is compensated for by the battery output. When the battery output is less than the battery output stopping threshold, the engine speed is increased to compensate for the second difference by the output of the alternator 3. To compensate for the second difference, a target engine speed is determined using a relationship of the second difference and the target engine speed. The engine speed is converged at the target engine speed.

    摘要: A power generator starts an engine by overcoming an inrush current occurs. A calculator (21) retrieves an outputtable current of a generator according to an engine speed. A calculator (23) calculates the lacking amount of the outputtable current relative to a load current. When the remaining battery level is sufficient, a DC/DC converter controller (24) supplies a current corresponding to the lacking amount from the battery (4) to a DC part (52). If the battery (4) starts supplying a power, FETs (Qa to Qf) of a rectifying part (51) are powered off and an output of the power generator (3) is stopped. When an engine frequency stability deciding part (27) decides the engine frequency is stable the rectifying part (51) restarts the output of the generator (3) and the current supply from the battery (4) to the DC part (52) is stopped.

    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: In an apparatus for controlling warm-up operation of a general-purpose internal combustion engine having a throttle valve installed in an air intake pipe and connectable to an operating machine to be used as a prime mover of the machine, it is configured to calculate a basic fuel injection amount based on an engine speed and a throttle opening and control engine warm-up operation by calculating a warm-up time fuel injection amount by correcting the calculated basic fuel injection amount based on one of a temperature change amount of a spark plug seat of the engine, the throttle opening and an output of the operating machine and injecting fuel from an injector by the calculated warm-up time fuel injection amount. With this, it becomes possible to calculate a fuel injection amount suitable for the engine warm-up condition by using an appropriate parameter in place of the lubricating oil temperature.
