    摘要： An engine control method, based on engine intake pressure, is operable to shorten a period from a start of cranking until a sequential fuel injection control is determined. Provisional and final stroke determinations are made for a plurality of cylinders from a synthetic manifold pressure waveform. The provisional stroke determination is made after a crankshaft is rotated 720 degrees after settlement of a crank reference position. The final stroke determination is made when the crankshaft rotates 1440 degrees after the provisional stroke determination. When the provisional stroke determination is made, fuel is injected into the cylinders based on a detected value of the engine intake pressure; and when the stroke determination is finally settled, the fuel injection and ignition of the engine are controlled based on the detected value of the engine intake pressure.

    摘要： An engine ignition control apparatus for controlling ignition of a multi-cylinder, 4-cycle engine includes dual ignition coils for controlling ignition timing of the respective cylinders during engine operation. The engine ignition control apparatus includes a stroke determination unit for determining a stroke based on crank pulses and on an output signal of an intake pressure sensor. The engine ignition control apparatus also includes an ignition map allocation unit for allocating ignition maps to the respective cylinders of two ignition systems, each having a pair of cylinders with a same phase, before the stroke determination. The ignition map allocation unit also allocates ignition maps independently to each of the respective cylinders after the stroke determination. The engine ignition control apparatus also includes an ignition timing calculation unit for calculating ignition timing of the respective ignition coils based on the ignition maps allocated to the respective cylinders.

    摘要： A fuel injection control apparatus is capable of supplying a proper amount of fuel by improving response when the throttle position is abruptly changed. The fuel injection control apparatus includes an electronic control unit for determining a fuel injection time period for a fuel injection system, based on the engine speed and the throttle position. The electronic control unit is operable to determine a base fuel injection time period based on engine speed and throttle position to start fuel injection, and adjusts the initial fuel injection time period thereafter, based on changes in the engine speed and the throttle position.
