    摘要： A pulse signal generator using a magnetic device that can cause a large Barkhausen effect, comprises means having a number of pits and projections and generates pulses according to the behavior of these, the means being capable of moving the pits and projections in a first or second direction, the pits and projections being disposed in the moving direction with some of the projections missing or some of the pits filled. The value of the ratio between the time interval of pulses generated by portions other than a projection-missing portion and the time interval of pulses generated by the projection-missing portion or the value of the ratio between the time interval of pulses generated by portions other than a pit-filled portion and the time interval of pulses generated by the pit-filled portion differs between when the pits and projections move in the first or second direction.

    摘要： A control system for an internal combustion engine having a fuel injector located in a combustion chamber of the engine for injecting fuel into the combustion chamber. The fuel injection timing stored in a fuel injection timing map is retrieved according to the detected engine operating condition to determine the fuel injection timing. An actual ignition timing of the fuel injected into the combustion chamber is detected. An ignition delay of the actual ignition timing with respect to the target ignition timing, which is set according to the engine operating condition and a fuel injection timing correction amount, is calculated according to the calculated ignition delay. The fuel injection timing is corrected with the fuel injection timing correction amount, and the fuel injection is executed according to the corrected fuel injection timing.

    摘要： A control system for an internal combustion engine having fuel injectors for injecting fuel into a combustion chamber of the engine. A fuel property is estimated based on a combustion state of the fuel injected into at least one cylinder of the engine. The fuel injectors are controlled so that a specific amount of fuel is injected into the at least one cylinder and an amount of fuel corresponding to an operating condition of the engine is injected into cylinders other than the at least one cylinder. An additional fuel injection is performed after the fuel injection of the specific amount with respect to the at least one cylinder, for example, when a torque difference parameter indicative of a difference between a torque generated by the at least one cylinder and a torque generated by the other cylinders is equal to or greater than a predetermined threshold value.

    摘要： A control system for an internal combustion engine, which makes it possible to estimate a fuel property parameter indicative of a property of fuel in use, in a plurality of operation modes of the engine, respectively, to thereby increase the chances of estimation of the fuel property parameter, and select an appropriate one from the estimated fuel property parameters to thereby more appropriately control the engine. The fuel property parameter is estimated when the detected operating conditions of the engine correspond to any of a plurality of operation modes. Depending on a plurality of fuel property parameters estimated in respective operation modes, one of the fuel property parameters is determined as the fuel property parameter for control of the engine.
