摘要： Combustion stability can be improved while HC and PN discharged from a combustion chamber are prevented. In an ECU that controls a fuel injection device installed in a combustion chamber of an internal-combustion engine so as to be able to inject fuel in a direction intersecting with a sliding direction of a piston, a pressure value of the fuel supplied to the fuel injection device is acquired, control is performed such that the fuel injection device injects the fuel at least twice in a compression stroke, and control is performed such that fuel injection timing of at least one time in the compression stroke is advanced earlier than fuel injection timing of a time corresponding to the high pressure value of the fuel when the acquired fuel pressure value is low.

摘要： In an internal combustion engine, combustion stability is improved while exhaust gas emission is suppressed. For this purpose, a control device (1) for controlling an injector (103) is configured to include a control unit (21) that controls the injector (103) to perform a first fuel injection (1001) for injecting fuel at a first fuel pressure from the injector (103) in an intake stroke (S1) in one combustion cycle of an internal combustion engine (100) and a second fuel injection (1002) for injecting fuel at a second fuel pressure higher than the first fuel pressure from the injector (103) after the first fuel injection (1001) in the same one combustion cycle in the intake stroke (S1).

摘要： Provided is a fuel injection device and a control unit therefor which enable reliable ignition even in a case where fuel pressure is low immediately after starting an engine.In the control unit for controlling an injector injecting fuel into an internal combustion engine, a plurality of injectors is provided in the internal combustion engine, a static flow rate of a first injector is configured to be smaller than a static flow rate of a second injector. In a case where a fuel pressure of fuel supplied by a pressurizing unit is lower than a set value set lower than a fuel pressure in warming up, an injection ratio of the first injector is controlled to increase according to a difference between a fuel pressure of fuel from the pressurizing unit and a fuel pressure in warming up.

摘要： Because an in-cylinder temperature becomes low immediately after cold starting, it is impossible to take large ignition timing retard to avoid combustion instability and it takes time to activate a catalyst existing downstream of an internal combustion engine.The present invention provides an internal combustion engine control apparatus including an ignition timing control unit to control an ignition timing of an ignition device attached to an internal combustion engine. The internal combustion engine control apparatus includes an in-cylinder temperature raising unit that raises an in-cylinder temperature, the in-cylinder temperature is raised by the in-cylinder temperature raising unit, and a retard amount of the ignition timing of the ignition device is increased by the ignition timing control unit.

摘要： The purpose of the present invention is to provide a parking assist device for a vehicle such that the vehicle can be parked without decreasing or excessively increasing the speed or causing the vehicle to stop during assisted parking, the speed of the host vehicle is kept constant even immediately after an obstacle or a bump is cleared, and the vehicle is prevented from colliding with any other parked vehicle. The device calculates a speed command value and/or an engine torque command value in consideration of the acceleration/deceleration of the vehicle and controls the speed of the vehicle on the basis of the calculated speed command value and/or the engine torque command value, said acceleration/deceleration being predicted in advance on the basis of the height and distance of an obstacle and/or a bump that is present in a parking path, the gradient of the road surface, and the steering angle.
