摘要： A driving force control device for a vehicle is provided, which includes a motor, an engine, and a controller. The controller sets a target torque of the vehicle corresponding to accelerator operation, distributes a target engine torque, based on the target torque, and outputs a control signal corresponding to the target engine torque. The controller estimates an amount of intake air into a cylinder in the future based on the target engine torque, and estimates an engine torque after a setup time from the present time based on the estimated amount of intake air. The controller sets a target motor torque after the setup time based on the estimated engine torque after the setup time so that the target torque is achieved, and outputs a control signal corresponding to the target motor torque to synchronize a torque response of the engine with a torque response of the motor.

摘要： A control system for a compression ignition engine configured to start compression ignition combustion by igniting mixture gas formed by injecting fuel into combustion chambers is provided, which includes combustion chambers each defined in respective cylinders so that displacements of the combustion chambers change by respective pistons reciprocating, a throttle valve, ignition plugs, injectors, a sensor having measuring parts including an atmospheric-pressure detector configured to detect an atmospheric pressure, and configured to measure parameters related to operation of the engine, and a controller. The controller executes a lean compression ignition combustion control in which compression ignition combustion is performed at a given lean air-fuel ratio higher than a stoichiometric air-fuel ratio. The controller restricts the execution of the lean compression ignition combustion control when the controller determines that the atmospheric pressure is lower than a given threshold based on a signal outputted from the atmospheric-pressure detector.

摘要： A control system for a compression ignition engine is provided, which includes a combustion chamber, a throttle valve, an injector, an ignition, a swirl control valve, a sensor and a controller. The controller is configured to execute a first mode module, a second mode module, and a changing module to change an engine mode from a first mode to a second mode in response to a change demand. The changing module outputs signals to the throttle valve and the injector in response to the demand so that an air-fuel ratio of mixture gas becomes a stoichiometric air-fuel ratio or a substantially stoichiometric air-fuel ratio, and outputs a signal to the swirl control valve so that an EGR gas amount decreases more than before the demand, and when the EGR gas amount is determined to be decreased to a given amount, the changing module causes the second mode module to start the second mode.

摘要： A combustion control device for an engine includes a plurality of cylinders, a surge tank disposed in an intake path to the cylinders, an independent intake passage connecting the surge tank and an intake port of each of the cylinders, a fuel injection valve that is disposed for each of the cylinders and that supplies fuel into each of the cylinders, and a control unit that controls a fuel injection amount of each of the fuel injection valves according to an engine operating state. The control unit corrects a target fuel injection amount of each of the cylinders, the target fuel injection amount being determined according to the engine operating state, based on a re-intake correction amount set in each of the cylinders according to a re-intake amount of intake air from the intake port in internal EGR in each of the cylinders.

摘要： A control device is provided for a compression ignition engine, which controls so that partial compression ignition combustion of A/F-lean mixture gas is carried out in a specific range where an engine load is low. In a first range of the specific range, a normal ignition in which sparks are generated in a late period of compression stroke or an early period of expansion stroke to start SI combustion, and a preceding ignition in which sparks are generated at a timing included in intake stroke or compression stroke and earlier than the normal ignition by a given amount or more are performed, and fuel is injected at a timing where fuel is present before the preceding ignition inside the combustion chamber. In a high-load side second range of the specific range, at least the normal ignition is performed and the execution of the preceding ignition is limited.

摘要： The control apparatus for a compression ignition type engine includes a plurality of cylinder inner pressure sensors that detect pressure in each cylinder, and a combustion control unit. The combustion control unit corrects a target fuel injection amount of each cylinder by an injector based on a deviation between a predicted combustion period that is a period from an ignition timing by an ignition plug to a predetermined mass combustion timing and that is obtained based on a preset combustion model, and an actual combustion period that is a period from the ignition timing by the ignition plug to an actual combustion timing and that is obtained based on cylinder inner pressure, such that the period from the ignition timing by the ignition plug to the predetermined mass combustion timing, which is the timing when fuel having a predetermined mass ratio combusts, is equalized in each cylinder.
