Abstract:
There is provided a hybrid vehicle capable of attaining excellent acceleration response and reducing pumping loss. When an engine combustion stop demand is issued, the engine is associatively rotated by carrying out a fuel cut-off operation and controlling the speed of a generator to control the engine in such a way that the speed of the engine becomes a predetermined speed NE1. During the associative rotation, intake and exhaust valves are held at their fully closed positions.
Abstract:
An exhaust gas purification device of an engine comprising a particulate filter arranged in an exhaust passage. An electric motor able to impart a vehicle drive power separate from the engine and able to generate electric power from the engine is provided. After the particulate filter finishes being warmed up, when the temperature of the particulate filter is low, the output torque of the engine is increased and the amount of increase of the output torque is consumed by the power generating action of the electric motor.

Abstract:
The present invention is directed to a complementary regenerative torque system for a vehicle including an engine with an accelerator pedal position sensor. The regenerative torque system selectively stores and supplies energy to the drive train of the vehicle to provide on demand complementary torque. The regenerative torque system may be hydraulic or electric in nature and may be disposed upstream or downstream of the transmission relative to the engine. A regenerative torque control module is disposed between the accelerator pedal position sensor and the engine control module and intercepts the accelerator pedal position signal and modifies it in response to the mode of operation of the regenerative torque system and forwards the modified throttle signal to the engine control module. Likewise, the regenerative torque control module intercepts and modifies signals from the engine control module prior to broadcasting them to the rest of the vehicle’s control modules.
Abstract:
The present invention provides a control apparatus of a direct injection internal combustion engine (1), used in an idling stop vehicle or the like, which can reduce residual fuel generated in a combustion chamber (101c) in an engine stop time, and prevent deterioration of exhaust performance and deterioration of exhaust gas performance (A/F control precision) at the time of engine restart. The control apparatus includes an automatic stop control device for automatically stopping an internal combustion engine (1), upon satisfaction of a predetermined automatic stop condition, and at least one of a fuel injection control unit which corrects fuel injection and an air-flow amount control unit which corrects an air-flow amount. Upon satisfaction of the predetermined automatic stop condition, at least one of fuel injection correcting control by the fuel injection control unit and air-flow amount correcting control by the air-flow amount control unit is performed.
Abstract:
The priority sequence in a control of adjusting the drive power with respect to a vehicle drive power request is set in the sequence of an engine output increase, a motor output increase and a gear speed change in a gear ratio increasing direction. More specifically, a gear speed of a least gear ratio is selected within such a range that an engine revolution speed higher than or equal to a predetermined lower limit revolution speed is attainable. (S12, S14) A requested drive power is achieved singly by an engine output with the gear speed selected. (S16) When the requested drive power is not achievable singly by the engine output, the requested drive power is achieved by the engine output and a motor output. (S18) When the requested drive power is not achievable by the engine output and the motor output, the gear speed is changed in a gear ratio increasing direction. (S20)
Abstract:
There is provided an energy recovery mechanism in a vehicle engine, which can improve fuel consumption and reduce exhaust gas emission while restricting a cost increase where possible. A driving/generating motor 26 is disposed between an outer peripheral surface of a rotating member 24 of the power transmission mechanism 5 and an inner surface of a rotating member housing portion 25a of the transmission case 25.
Abstract:
A catalytic emission control apparatus of an internal combustion engine (1) that has an engine stop mode of stopping the internal combustion engine (1) during a run of a vehicle utilizes an oxygen absorption-storage action of an emission control catalyst (18) disposed in an exhaust passage (7) of the internal combustion engine (1). The emission control apparatus has storage computing means (18) for computing a storage of oxygen in the emission control catalyst (19), and air-fuel ratio control means (18) for performing an air-fuel ratio control of the internal combustion engine (1) based on the storage of oxygen computed by the storage computing means (18). The storage computing means (18) computes the storage of oxygen during the engine stop mode of the internal combustion engine (1). The air-fuel ratio control means (18) performs the air-fuel ratio control when the internal combustion engine (1) is restarted after the engine stop mode is discontinued, based on the storage of oxygen computed by the storage computing means (18) during the engine stop mode.
