    摘要： An accelerated state is detected as soon as possible at the engine start at which a crank pulse alone is insufficient to identify the stroke, and erroneous detection of the accelerated state is prevented. In a period from cranking start to stroke detection, data on suction air pressure is stored for each crank pulse in a virtual address, and during stroke detection, when the virtual address does not coincide with the normal address corresponding to the stroke, the data on the suction air pressure stored in the virtual address is transferred to the normal address, and thereafter the data on the suction air pressure is stored in the normal address, thereby making it possible to detect the accelerated state by making comparison, immediately after the stroke detection, with the suction air pressure prevailing one cycle before. Further, detection of an accelerated state is inhibited when the engine rpm variation is high wherein the suction air pressure increase state during the closure of the suction air valve does not become stable and also when the engine load is high.

    摘要： To provide a method of processing intake air pressure signals for accurately detecting the engine load including the accelerating state and the intake air flow rate from the intake air pressure.Intake air pressure signals detected with an intake air pressure sensor 15 are processed with a low-pass filter. The low-pass filter is set to cut off frequencies that are not higher than the frequency corresponding to the wavelength that is four times the length of a pressure guide pipe 23 leading to the pressure sensor 15 and to cut off frequencies that are not lower than the driving frequency of the intake valve, which eliminates electric noises and air column vibration occurring in the pressure guide pipe 23 and makes it possible to obtain smooth and real changes in the intake air pressure commensurate with the strokes.

    摘要： An engine control device is provided to reliably detect an abnormality in crank pulses. The device determines that there is an abnormality in crank pulses when the situation, in which a standard pitch crank pulse counter T does not reach a prescribed value T0 between irregular pitch crank pulses (interval abnormality), repeatedly occurs at least a prescribed value CNT0 times, when an irregular pitch is not detected for a prescribed period of time for the crank pulse counter T to count up to TMAX or longer, or when the situation, in which a prescribed number or more of clank pulses are not detected for a prescribed period of time, repeatedly occurs at least a count-up value KMAX of times.

    摘要： A number of embodiments of engine controls and engine control methods that employ instantaneous rate of combustion is the combustion chamber at a sensed parameter. Rate of combustion is determined by a linear equation based upon data arrived from combustion chamber pressures. The system is adapted to operate under different control modes so as to provide specific control for normal running, lean burn, maximum torque, cold starting, transient conditions, and/or knock control. The desired rate of combustion is achieved by engine control adjustments.

    摘要： Startability of an internal combustion engine using a mixed fuel of gasoline and alcohol is improved. An intake passage of the engine has a main flow channel provided with a throttle valve and a bypass flow channel for bypassing the throttle valve. A bypass quantity adjusting mechanism adjusts the bypass quantity in the bypass flow channel. A control device detects or estimates the mixing ratio of alcohol of the fuel and controls the bypass quantity adjusting mechanism so that a bypass quantity before a first explosion is smaller than a bypass quantity after the first explosion when the mixing ratio of alcohol is equal to or more than a predetermined value.
