摘要： PROBLEM TO BE SOLVED: To restrain pulsation generated in an intake pipe, when increasing opening of a throttle valve arranged in the intake pipe.
SOLUTION: When trying to reduce a pump loss by increasing the opening of the throttle valve 56, predetermined opening smaller than the opening of the throttle valve 56 in full opening is set as an upper limit of the throttle valve opening on the basis of the size of the pulsation generated in the intake pipes 51 and 52, and the opening of the throttle valve 56 is increased so as not to exceed its limit. When a throttle valve 56' and an idle speed control valve 58 are arranged, an upper limit of the total opening of the throttle valve 56' and the idle speed control valve 58 is arranged.

摘要： PROBLEM TO BE SOLVED: To suppress frequent changeover of compression ratio of an internal combustion engine. SOLUTION: This power output device comprises: the internal combustion engine operated while its compression ratio is changed in response to a required torque; and a transmission for changing deceleration ratio. When the torque required for the internal combustion engine exceeds a torque defining a threshold for altering the compression ratio, the deceleration ratio of the transmission is changed to a large value. When the deceleration ratio is changed to a large value, the torque to be outputted from the internal combustion engine is decreased, so that the changeover of the compression ratio is suppressed.

摘要： PROBLEM TO BE SOLVED: To simultaneously improve the thermal efficiency and maximum output of an internal combustion engine by appropriately switching the compression ratio, air-fuel ratio and supercharging state of the internal combustion engine according to the operating conditions. SOLUTION: With the increase of demand torque, the combination of the compression ratio, air-fuel ratio and supercharging state of the internal combustion engine is sequentially switched to (1) [high compression ratio state/lean air-fuel ratio/no supercharging]→(2) [high compression ratio state/lean air-fuel ratio/with supercharging]→(3) [low compression ratio state/lean air-fuel ratio/with supercharging]→(4) [low compression ratio state/stoichiometric air-fuel ratio/with supercharging]. The operating region of the internal combustion engine in the high compression ratio state or the lean air-fuel ratio state with high thermal efficiency can be taken large. In a high demand torque region, the internal combustion engine can be operated while supercharging a stoichiometric mixture at the low compression ratio, so that sufficiently large torque can be outputted.

摘要： PROBLEM TO BE SOLVED: To prevent a variety of adverse effects caused by misfire of an internal combustion engine. SOLUTION: When misfire occurs, emission of air-fuel mixture from a misfiring combustion chamber is controlled or stopped. By doing so, air-fuel mixture remaining in the combustion chamber can be burned in the next cycle, and exhausted after power generation. As a result, this can prevent adverse effects, such as deterioration of fuel consumption rate, increase in emission of air pollutants, and deterioration of purifying catalysts. Also, the air-fuel mixture exhausted from the misfiring combustion chamber can be returned to other combustion chambers and burned. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To appropriately start a compression self-ignition engine mounted into a hybrid vehicle. SOLUTION: When the need to start the engine is determined, prior to the start, a motor of the hybrid vehicle is driven to increase the rotating speed of the engine. The engine is started after confirming that the engine speed has reached a first threshold rotating speed Nth1. The first threshold rotating speed is set to the rotating speed which allows the compression self-ignition operation of the engine. The engine can thus be started appropriately while being put in compression self-ignition operation. COPYRIGHT: (C)2004,JPO
