摘要： A variable displacement oil pump includes: a variable displacement mechanism that is able to change a discharge amount per rotation of an input shaft. The variable displacement mechanism includes a pump housing, an oil pressure chamber provided in the pump housing, and a capacity adjustment member displaced by oil pressure from the oil pressure chamber. The capacity adjustment member is configured to be operated when receiving control oil pressure that is supplied from a control valve to the oil pressure chamber. The pump housing has an oil release hole that is opened to face the oil pressure chamber and that penetrates a wall section of the pump housing to partially release oil.

摘要： Provided is a control apparatus for a supercharged internal combustion engine, which can favorably achieve a good balance between prevention of overheat of a catalyst disposed an exhaust passage and suppression of turbo lag, in a case in which a fresh air blow-through is generated through a combustion chamber from an intake passage to an exhaust passage. A turbo supercharger (22), an exhaust bypass passage (36), a WGV (38) capable of switching the opening and closing of the exhaust bypass passage (36), and variable valve operating mechanisms (46, 48) capable of changing a valve overlap period are included. The valve overlap period is shortened so that the fresh air blow-through amount Gsca becomes equal to or smaller than a predetermined blow-through determination value Gjudge when the blow-through amount Gsca is larger than the blow-through determination value Gjudge. The WGV (38) is opened when the blow-through amount Gsca is still larger than the blow-through determination value Gjudge after the valve overlap period has been shortened.

摘要： A convergence determination of intake valve phase control is made by comparing a phase deviation of an intake valve from a target phase with a convergence determination value. At the time of convergence, it is determined that the intake valve phase has reached the target phase, so that the required phase-change amount of a camshaft is set to zero and therefore the actuator operation amount is also set to zero. At the time of engine stop when the target phase has a fixed value, after convergence of the intake valve phase control, the operation of the actuator is stopped. In addition, during the course of engine stop, the convergence determination value is set to be switched from the time of engine operation so that the convergence determination of the intake valve phase control is made in more relaxed conditions compared with at the time of engine operation.

摘要： An engine has a variable valve actuation mechanism that varies lift characteristics of an intake valve. An idle speed control apparatus has a control section for controlling an intake air amount of the engine in an idle state for adjusting an actual engine speed to a target engine speed. The control section sets a control amount related to control of the intake air amount in correspondence with the lift characteristics, which are varied by the variable valve actuation mechanism. Accordingly, the engine speed in the idle state is effectively controlled in correspondence with changes of the lift characteristics.

摘要： Based on results of a knock control for adjusting ignition timing in accordance with the occurrence of knocking, an electronic control unit computes deposit required ignition timing akgrg, which is ignition timing determined by taking adhesion of deposits in an internal combustion engine into consideration. Based on the deposit required ignition timing akgrg, the electronic control unit reduces a vvt allowable variable range of a target VVT advancement amount, which is a control target value of a variable valve timing mechanism. The electronic control unit corrects a required ignition timing based on the actual VVT advancement amount vt, which is chanted according to the reduction of the allowable variable range of the target VVT advancement amount. As a result, problems resulting from the adhesion of deposits are effectively avoided.

摘要： A fuel-injected engine is operated in a compression stroke injection mode or an intake stroke injection mode. The intake flow rate appropriate for the compression stroke injection mode is greater than that of the intake stroke injection mode. When the engine is cold, the ECU determines the amount of fuel injected in accordance with the actual intake flow rate. The ECU controls a throttle valve such that the intake flow rate is appropriate for the selected fuel injection mode before the fuel injection mode is actually switched. As a result, fluctuations of the engine speed caused by switching the fuel injection mode are reduced.

摘要： An engine has an injector, which directly injects fuel into a combustion chamber. When the coolant temperature during the cranking of the engine is low, an ECU controls the injector such that the engine is operated in a compression stroke injection mode. When the engine is operated in the compression stroke injection mode, the ECU controls the injector to advance the fuel injection timing in accordance with an increase of the coolant temperature. As a result, the engine reduces the amount of unburned discharge gas, provides improved ignition and combustion, and provides stable idling.
