Patent ID: 6934623

Claim:
An engine controller comprising: phase detecting means for detecting the phase of a crankshaft in a four-stroke cycle engine; suction air pressure detecting means for detecting a suction air pressure within a suction air passage of said engine; accelerated state detecting means for detecting an accelerated state when a difference value between a previous suction air pressure and a present suction air pressure detected at the same stroke in the same crankshaft phase by said suction air pressure detecting means is greater than or equal to a predetermined value; acceleration fuel injection quantity setting means for setting an acceleration fuel injection quantity injected from the fuel injection equipment when said accelerated state detecting means detects the accelerated state; engine operating condition detecting means for detecting an operating condition of the engine; and accelerated state detection inhibiting means for inhibiting said accelerated state detecting means from detecting the accelerated state depending on the operating condition of the engine detected by said engine operating condition detecting means.
