摘要： An EGR control system that is capable of controlling the amount of recirculation of high-temperature and low-temperature recirculated gases, with high accuracy, to thereby improve the control accuracy of in-cylinder temperature. An ECU of an ERG control system calculates a fresh intake air ratio, and sets a target value of the fresh intake air ratio. The ECU calculates a feedback correction coefficient for converging the fresh intake air ratio to the target value, with an I-PD control algorithm, and sets an external EGR ratio and an internal EGR ratio. The ECU controls the EGR amount whose ratio is the larger, according to the larger one of the two ratios and the feedback correction coefficient, and controls the EGR amount whose ratio is the smaller, according to the smaller of the ratios and the learned value thereof.

摘要： In a control system for a compression-ignition engine whose operation is switchable between a compression-ignition operation in which an air-fuel mixture supplied to a combustion chamber auto-ignites to burn owing to compression and a spark-ignition operation in which the air-fuel mixture is ignited to burn by a spark of a spark plug, it is determined whether a predetermined prohibitive condition to prohibit switching from the spark-ignition to the compression-ignition operation is satisfied, and switching from the spark-ignition operation to the compression-ignition operation is prohibited when the predetermined prohibitive condition is satisfied, thereby enabling to avoid premature ignition and misfire and to prevent drivability and fuel consumption performance from being affected therefrom.

摘要： There is provided a control system for an internal combustion engine, which is capable of matching an output torque of the engine with a demanded torque excellently when the combustion mode is switched, thereby enhancing drivability. A demanded fuel amount and a demanded torque of the engine are calculated according to detected operating conditions of the engine. A combustion mode is determined to be either the stratified combustion mode or the homogeneous combustion mode according to the demanded torque. A pre-switching demanded fuel injection time period and a pre-switching demanded torque are stored. When the combustion mode is switched, a switching-time demanded fuel amount (limit value) is calculated according to the stored pre-switching demanded fuel injection time period and pre-switching demanded torque, the current demanded torque, and an estimated combustion efficiency parameter.

摘要： In a vehicle designed so that a driven wheel is driven by uniting an output from an engine and an output from a Rankine cycle system to each other, an accelerator pedal and a throttle valve are connected electrically to each other by a DBW control unit. When an accelerator opening degree (θap) commanded by a driver is increased, a throttle opening degree (θth) is increased by a correcting amount (Δθth) more than a value proportional to the accelerator opening degree (θap), thereby compensating for an output shortage due to a response delay of the output from the Rankine cycle system. When the accelerator opening degree (θap) commanded by the driver is decreased, the throttle opening degree (θth) is decreased by the correcting amount (Δθth) more than the value proportional to the accelerator opening degree (θap), thereby compensating for an output excessiveness due to the response delay of the output from the Rankine cycle system.

摘要： There are provided a control system and method and an engine control unit for an internal combustion engine including two types of variable valve mechanisms capable of changing a camp phase and a cam profile, respectively, which system is capable of determining an amount of fuel to be injected as a value suited to charging efficiency at the time by simplified calculation processing, thereby performing the fuel injection control properly in a simplified manner. The fuel injection control system includes an ECU. The ECU searches a map for a multiplier term Ati for a high-speed cam or low-speed cam based on the rotational speed of the engine and the cam phase, and a map for an addend term Bti for the high-speed cam or the low-speed cam based on the rotational speed of the engine and the cam phase. The ECU calculates a basic fuel injection time period Tibase as the sum of the product of an intake pipe absolute pressure PBA and the multiplier term Ati and the addend term Bti (Ati×PBA+Bti).

摘要： Control system for an internal combustion engine, for setting a desired torque in response to operating conditions of the engine and controlling torque based on the set desired torque. A crank angle position sensor detects an engine rotational speed. An accelerator position sensor detects an accelerator position. A required torque is calculated based on results of detection by the crank angle position sensor and the accelerator position sensor. Further, the calculated required torque is smoothed. Then, the present value of the required torque calculated at the present time and the smoothed required torque are compared with each other. When it is determined that the engine is being accelerated, an acceleration assist amount is calculated based on a difference value between the present value of the required torque and the smoothed required torque. Then, the acceleration assist amount is added to the smoothed required torque, whereby the desired torque is set.

摘要： An engine exhaust gas purification system having a catalyst in an exhaust system of the engine, said catalyst reducing nitrogen oxide when exhaust gas generated by the engine is in an oxidizing state. In the system, engine operating parameters, including at least an engine speed and an engine load, are determined and catalyst temperature is determined, and air/fuel ratio is controlled in response to the detected parameters and the determined catalyst temperature, thereby enabling the catalyst to purify NOx in its optimum temperature characteristic range to achieve enhanced NOx constituent purification performance in an oxidizing environment. Alternatively, the air/fuel ratio is controlled in the stoichiometric or richer direction when the catalyst temperature is high, thereby protecting the catalyst from being damaged. The catalyst is a selective-reduction type nitrogen oxide reduction catalyst.

摘要： A control system for an internal combustion engine having a plurality of cylinders each having at least one intake valve, at least one exhaust valve, and a crankshaft. The control system has an electromagnetic driving section which electromagnetically causes opening and closing of at least one of the at least one intake valve and the at least one exhaust valve. A crank angle sensor generates a crank angle signal whenever the crankshaft rotates through a predetermined angle, and a cylinder position sensor generates a cylinder-discriminating signal indicative of a predetermined crank angle of a particular cylinder of a plurality of the cylinders. A piston position sensor detects an operating state or position of the piston of each of the plurality of the cylinders, based on the generated crank angle signal and the generated cylinder-discriminating signal. A CPU starts opening of the at least one of the at least one intake valve and the at least one exhaust valve, based on the detected operating state of the piston.
