Abstract: PROBLEM TO BE SOLVED: To make effective use of the regenerative power of a motor and enhance the energy efficiency of an entire vehicle in an automobile provided with the motor capable of generating power by power from an axle. SOLUTION: The automobile is provided with the motor MG2 connected with driving wheels 39a and 39b. When the regenerative power of the motor MG2 exceeds a limit value on the power with which a battery 50 can be charged, the excess power is consumed at an electric heater 66 and is stored as heat in a heat accumulation tank 65. When a request is made to start an engine 22, the setting of a three-way valve 68 is changed so that the heat exchange medium in the heat accumulation tank 65 is supplied to the engine 22 until the engine water temperature becomes equal to or higher than a predetermined temperature. Thus, the regenerative power of the motor MG2 can be utilized without wastage as required, and the energy efficiency of the vehicle can be further enhanced. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide a power output apparatus reducing hydrocarbon emissions during the cold start of an engine.
SOLUTION: During the catalyst warm-up period, when the control enabling reduction in hydrocarbon emissions is not executed in a gasoline engine 100, the opening of a throttle valve 101 is made smaller in order to reduce hydrocarbon emissions. During the catalyst warm-up period, when the control enabling reduction in hydrocarbon emissions is executed in the gasoline engine 100, the opening of the throttle valve 101 is made larger in order to accelerate warm-up of the catalyst, thereby shortening the catalyst warm-up period. A shorter catalyst warm-up period enables reduction in the total hydrocarbon emissions from engine startup to the end of the catalyst warm-up period.
