FUEL CONTROL METHOD FOR HANDHELD ENGINE OPERATING MACHINE
摘要
A method for making an optimum combustion during engine operating time changes a fuel flow rate of the solenoid valve on the basis of engine rotational speed feedback control during engine idling time at low engine rotational speed and low electric power consumption. During engine idling time of an engine are carried out a rotational speed detecting process, an idle rotation adjusting process of making a rotational speed detected by the rotational speed detecting process equal to an initial value of rotational speed by controlling an ignition timing while comparing the detected rotational speed with the initial value of rotational speed as target value, and a valve opening correction process according to idle ignition timing change (I.I.T.C.) obtained by the idle rotation adjusting process. The valve opening is set to an adjusted valve opening (A.V.O.) plus a correction valve opening (C.V.O.) by the valve opening correction process.
