摘要： PROBLEM TO BE SOLVED: To provide a cylinder injection type spark ignition internal combustion engine capable of enlarging a stratified charge combustion operation range to a high- rotation and high-load side and capable of achieving excellent homogenous combustion without adhesion of fuel to a cylinder bore even when fuel injection at a suction stroke is performed for the homogeneous combustion in the high-rotation and high-load state. SOLUTION: Nearly sector spray 10 injected from a fuel injection valve 6 always collides with an inside of a cavity 8 when a piston positions at a top dead center side from an intermediate point. The nearly sector spray injected from the fuel injection valve is always directed to a top surface of the piston outside the cavity without collision with the cylinder bore when the piston positions at a bottom dead center side from the intermediate point. As for the stratified charge combustion, the fuel injection valve performs the fuel injection when the piton positions between the intermediate position and the top dead center in a compression stroke. As for the homogeneous combustion, the fuel injection valve starts the fuel injection when the piston positions just before the intermediate point in the intake stroke. An ignition plug is arranged so as to confront the inside of the cavity.
摘要翻译：要解决的问题：提供一种能够将分层充气燃烧操作范围扩大到高旋转和高负荷侧的气缸喷射式火花点火内燃机，并且能够实现优异的均匀燃烧而不会将燃料附着到气缸孔即使在高旋转高负荷状态下的均匀燃烧中进行吸入冲程的燃料喷射。解决方案：当活塞从中间点位于上止点处时，从燃料喷射阀6喷射的几乎扇形喷雾10总是与空腔8的内部碰撞。当活塞从中间点位于下止点侧时，从燃料喷射阀喷射的几乎扇形的喷雾总是被引向活塞外部空腔的顶表面而不与气缸孔碰撞。对于分层充气燃烧，当压缩冲程中的中间位置和上止点之间的俯仰位置时，燃料喷射阀执行燃料喷射。对于均匀燃烧，当活塞位于进气冲程中的中间点之前时，燃料喷射阀开始喷射燃料。火花塞被布置成面对空腔的内部。

摘要： PROBLEM TO BE SOLVED: To materialize reduction of noise and vibration, and miniaturization of a rotary engine.
SOLUTION: A plurality of rotors 2a - 2d are stored in a common space enclosed by a rotor housing 1 and side housings 4a, 4b. Eccentric parts 3a - 3d rotatably supporting the rotors 2a - 2d interlock with an output shaft 3 while keeping eccentricity to the output shaft 3 and keeping a condition where inertia force in eccentric rotation of the rotor is balanced by the whole rotors 2a - 2d stored in the common housing. Consequently, dynamic unbalance caused by eccentric motion of the rotors 2a - 2d is suppressed and rotor intervals are shortened by just that much of omitting the side housings between the rotors 2a - 2d.

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
