摘要： A control device for an internal combustion engine and a continuous variable transmission which enables well-responsible transmission control to be carried out at a proper transmission rate without increasing the transmission shock. When engine power corresponding to an engine power torque corrected amount is changeable, then an intake air flow adjusting unit is controlled in response to a corrected engine power torque corrected amount. On the contrary, when the corrected engine power torque corrected amount is not changeable, the amount corrected engine power torque corrected is restricted within a range where the engine power can be changed.

摘要： A control device of a lean-burn engine has an electronic control unit. Upon start of switching from stoichiometric driving to lean driving, the control unit (10) derives, from a map, a target pressure (P0) and a basic opening degree (D0) of an idling speed control valve, serving as an air bypass valve, based on the throttle opening degree (TPS) and the engine rotation speed (Ne) at the start of the switching. The control unit supplies driving pulses (N) of a number corresponding to the basic opening degree (D0) to a stepper motor (32) of the idling speed control valve. Then, the control unit supplies the stepper motor with driving pulses of a number corresponding to an opening degree correction amount (D1) which in turn corresponds to a deviation between the target intake pressure (P0) and an actual intake pressure (PB), to thereby suppress a change in the torque at the time of switching between the rich driving, including the stoichiometric driving, and the lean driving of the lean-burn engine.

摘要： Described herein is a drive-by-wire vehicle engine output control system. The system permits good-response acceleration by a driver's simple and reasonable operation, i.e., by operating an accelerator pedal and also a prompt response even when a sudden load change occurs. Further, the system permits precise speed control by simple equipment even when the deviation of a vehicle speed from a target vehicle speed is large. Output changes of an engine can be controlled within a permissible output change range by (a) comparing a target autocruise engine output with an acceleration demanding ending output, choosing the larger engine output and then controlling the engine to give the larger engine output, (b) controlling the engine to achieve a target autocruise engine output obtained from a speed correction torque and a running load torque or (c) limiting an engine control quantity on the basis of a permissible output change value.

摘要： In a control apparatus and control method for an internal combustion engine having an exhaust purifying catalytic device for adsorbing nitrogen oxide contained in exhaust gases from the engine, the adsorption state of nitrogen oxide adsorbed by the catalytic device is estimated by an electronic control unit during the lean-combustion driving of the engine. If the catalytic device is saturated with nitrogen oxide, the ignition timing is delayed and the exhaust gas is recirculated to the intake side of the engine with the lean air-fuel ratio kept unchanged. This starts the nitrogen oxide reduced driving mode for deteriorating the combustion state in the engine. At this time, the engine output will not change by a great amount. Further, a reducing atmosphere is created around the catalytic device by unburnt gases, generated due to the deterioration of the combustion state, to deoxidize the adsorbed nitrogen oxide. As a result, the purifying ability of the catalytic device can be recovered to suppress the discharge amount of nitrogen oxide without deteriorating the smoothness of engine driving and fuel economy.

摘要： An idle control system includes an engine speed determining unit, a unit for determining the number of operating cylinders, a valve stopping unit for stopping the operation of inlet and exhaust valves of some of the cylinders, an idle control parameter calculating unit, and an engine speed control unit. The idle control parameter calculating unit calculates at least a target idle speed and a target idle position as idle control parameters according to the data on the number of operating cylinders. The engine speed control unit controls an idle speed control valve so as to remove a deviation of an actual engine speed from the target engine speed, based on a target deviation compensating gain or a corrected target position obtained by a calculated position correcting unit. Thus, the idle control method performed by the idle control system allows the engine to operate stably even when the engine is switched to a partial operation from a full operation or vice versa and is subject to a sudden torque change during idling.

摘要： An air-fuel ratio control apparatus capable of preventing production of a torque shock which is liable to be caused in an engine when the air-fuel ratio is varied for a change between rich combustion and lean combustion. When the engine is in any other operating state than a specific operating state, an electronic control unit of the apparatus subjects a valve, which is disposed in a first bypass line for bypassing a throttle valve to on/off-duty control in accordance with the difference between a target suction air amount necessary for control for a lean air-fuel ration, computed according to a throttle valve opening detected by a throttle sensor, and a suction air amount detected by an airflow sensor, and urges a bypass valve for opening a negative-pressure responsive valve in a second bypass line. As a result, a predetermined amount of air is allowed to be supplied to the engine through the throttle valve and the first and second bypass lines. In the specific operating state, enough air supply through the throttle valve for control for a rich air-fuel ratio is allowed while preventing air supply through the bypass lines.
