摘要： A stroke determination unit for a 4-cycle engine uses intake pressure as a parameter to provide accurate stroke determination. A combined pressure combines the detected pressures of intake ports of the first to third cylinders, and stroke determination is carried out by recognizing, within a combined pressure waveform based on a detection value for the combined pressure, shapes of the combined pressure waveform for a specified phase period of a crankshaft. The pressure pattern recognition is carried out by storing variation patterns of pressure values measured within the specified crankshaft phase period, and collating patterns with a data map stored within an ECU. Alternatively, the pattern recognition is carried out by collating with condition equations representing “rising” or “upward peak”. With the latter, pressure variation due to contamination such as electrical noise to the pressure sensor is made negligible, and noise suppression of the stroke determination unit is improved.

摘要： When it is detected that any one of a plurality of variable valve characteristic mechanisms disposed for every cylinder groups is failed, an effective opening degree (valve lift amount, valve operating angle or the like) in a valve characteristic in the failed state, is obtained. When the effective opening degree is judged to be a predetermined value or above, the valve characteristic of the normal variable valve characteristic mechanism is controlled to be coincident with the valve characteristic in the failed state. When the effective opening degree is judged to be less than the predetermined value, there is performed a control for limiting the control to coincide the valve characteristic of the normal variable valve characteristic mechanism with the valve characteristic in the failed state.

摘要： In an internal combustion engine in which fuel injection valves are arranged upstream from and downstream from the throttle valve, respectively, the response of the accelerated increase in quantity and correction will be improved. The total injection quantity determination unit determines a total quantity of fuel to be injected from each fuel injection valve. The injection rate determination unit determines an injection rate of the upstream injection valve. The injection quantity correction unit includes an accelerated increase in quantity and correction unit, and during acceleration, increases and corrects only the injection quantity of the downstream injection valve during acceleration. The injection quantity determination unit determines the injection quantity of the upstream injection valve on the basis of the injection rate and the total injection quantity, and determines the injection quantity of the downstream injection valve on the basis of the upstream injection quantity and the total injection quantity.

摘要： A required fuel amount for an engine is calculated at a predetermined calculation cycle. A fuel injection amount to be injected from an upstream injection valve and a fuel injection amount to be injected from a downstream injection valve are then calculated. After fuel injection on the basis of the calculated fuel injection amounts, a lack of fuel delivered by the fuel injection amounts immediately before re-calculation of a required fuel amount at the calculation cycle until the end of an intake stroke (end of an intake valve opening period), is calculated by subtracting the fuel injection amounts from the re-calculated required fuel amount. The calculated lack of fuel amount is injected from the downstream injection valve during the intake stroke, e.g., in stages 6 and 7. A portion of a fuel injected from each of the fuel injection valves which has adhered on an inner wall of an intake pipe and subsequently released to be later supplied to the engine, is calculated in accordance with a predetermined adhesion ratio and a predetermined release ratio. The above lack of fuel amount is determined in consideration of the calculated portion of the fuel. The lack of fuel amount is additionally injected, e.g. a fuel correction amount, even during an engine transient state, and engine operability and fuel consumption are improved.
