    摘要： A hybrid vehicle includes an internal combustion engine, an electrical storage device, an electric motor, an exhaust emission control device, and a controller. The internal combustion engine includes a variable valve actuating device. The variable valve actuating device is configured to change an operation characteristic (IN1a, IN2a, IN3a) of an intake valve. The electrical storage device is configured to store electric power. The electric power is generated by using the internal combustion engine. The electric motor is configured to generate a driving force of the hybrid vehicle by using the electric power stored in the electrical storage device. The exhaust emission control device is configured to purify exhaust gas from the internal combustion engine with the use of a catalyst. The controller is configured to execute catalyst warm-up control. The catalyst warm-up control is control for warming up the catalyst of the exhaust emission control device. The catalyst warm-up control includes first control (FIRST WARM-UP CONTROL) and second control (SECOND WARM-UP CONTROL). The first control is control for operating the internal combustion engine at a first operating point (P1). The second control is control for, after the first control is executed, operating the internal combustion engine at a second operating (P2) point irrespective of a driving force that is required to propel the hybrid vehicle. An output of the internal combustion engine at the second operating point (P2) is larger than an output of the internal combustion engine at the first operating

    摘要： A multi-cylinder internal combustion engine (1) having four cylinders is provided with an EGR device (3) including an EGR cooler (27). The multi-cylinder internal combustion engine has: four exhaust side branch conduits (15) each being provided to each cylinder (2); a storage tank (31) which stores condensed water (CW) generated by the EGR cooler (27); and four condensed water introduction conduits (33) each being provided to each exhaust side branch conduit (15) and being communicated with the exhaust side branch conduit (15) and the storage tank (31). When the wall temperature of the cylinders (2) in the decelerating operation is equal to or more than a predetermined temperature, an exhaust-side variable valve mechanism (23B) and an intake-side variable valve mechanism (23A) are controlled respectively so that the valve closing timing of an exhaust valve (21) is retarded, and the valve opening timing of an intake valve (20) is retarded.

    摘要： A vehicle controller performs a throttle-valve-late-close control in which the throttle valve is held open until a delay time has passed after the fuel cut is started, and an EGR-valve-open-close control in which the EGR valve is repeatedly opened and closed. Then, the throttle valve is closed and the EGR valve is opened. In a period from a latter period of an exhaust stroke to a preceding period of an intake stroke, a valve-overlap control is executed so that a variable valve timing controller is controlled to make both an intake valve and an exhaust valve opened. A pumping loss of an engine is sufficiently reduced and an energy-regenerate efficiency can be effectively improved.
