摘要： A fuel cut during deceleration is executed at time point t1. An oxygen storage amount (rOS) which increases with this fuel cut is estimated based on an exhaust air-fuel ratio and an intake air quantity. When the oxygen storage amount (rOS) reaches a threshold value (at time point t2), a target compression ratio (tCR) is corrected to become lower than a basic target compression ratio (tCR). Although a fuel recovery is executed at time point t4, a combustion temperature is lowered because of the lowering of the mechanical compression ratio, so that a production of NOx in a combustion chamber is suppressed. Therefore, worsening of NOx is suppressed even if the oxygen storage amount (rOS) of exhaust-emission purification catalyst (4) is excessive.

摘要： At the time of increasing an actual intake air amount by increasing a valve overlap period of intake and exhaust valves (2; 3), an actual compression ratio is temporarily decreased to be lower than a steady-state target compression ratio. This makes it possible to increase the valve overlap period without causing interference of the intake and exhaust valves (2; 3) with a piston (8).

摘要： A control device for a variable compression ratio internal combustion engine is equipped with a variable compression ratio device capable of changing an engine compression ratio of the internal combustion engine. The control device detects or estimates the temperature of an exhaust component (B11), and sets a target exhaust gas temperature based on the temperature of the exhaust component (B12). A mixing ratio and compression ratio set section (B13) sets a fuel mixing ratio and the engine compression ratio within such a range as not to exceed the target exhaust gas temperature such that energy loss becomes minimum.

A hybrid vehicle comprises a first motor/generator (MG1) that is mechanically coupled to drive wheel (19), a second motor/generator (MG2) that is mechanically coupled to an internal combustion engine (ICE) and that has a smaller electrical power generation capability than the first motor/generator (MG1), and a high-power battery (3) that is electrically coupled to the two motor/generators (MG1, MG2), wherein, when starting the vehicle, an EV start is carried out using the first motor/generator (MG1) as a drive source. The hybrid vehicle is provided with a hybrid control module 21, which causes at least one of the two motor/generators (MG1, MG2) to generate power using the torque of the internal combustion engine (ICE). When the vehicle is stopped, this module (21) disconnects the first motor/generator (MG1) from the drive wheel (19) and connects same to the internal combustion engine (ICE), and power is generated by the first motor/generator (MG1) by receiving the torque from the internal combustion engine (ICE).摘要翻译： 提供一种用于混合动力车辆的发电控制装置，其能够确保车辆停止时启动所需的电力。 混合动力车辆包括机械联接到驱动轮（19）的第一电动机/发电机（MG1），机械联接到内燃机（ICE）的第二电动机/发电机（MG2），并且具有较小的电功率 （MG1）的发电能力，以及与两个电动机/发电机（MG1，MG2）电连接的高输出电池（3），其中，在启动车辆时，执行EV启动 使用第一台电动机/发电机（MG1）作为驱动源。 混合动力车辆设置有混合动力控制模块21，其使得两个电动机/发电机（MG1，MG2）中的至少一个使用内燃机（ICE）的转矩来发电。 当车辆停止时，该模块（21）将第一电动机/发电机（MG1）与驱动轮（19）断开并将其连接至内燃机（ICE），并且由第一电动机/发电机 MG1）通过接收来自内燃机（ICE）的扭矩。

摘要： An internal combustion engine (1) that has a variable-compression-ratio mechanism (2) has variable valve mechanisms (7, 8) for an intake valve (4) and an exhaust valve (5), respectively. If a malfunction in the variable-compression-ratio mechanism (2), which controls a mechanical compression ratio via an electric motor (31), is detected from the amplitude of variations in an actual compression ratio, then if the fuel supply to the engine is cut, a throttle valve (14) is opened wider than would be the case if the variable-compression-ratio mechanism (2) were not malfunctioning, thereby reducing in-cylinder negative pressure during the intake stroke. Also, the timing with which the intake valve is closed is advanced and the timing with which the exhaust valve is opened is retarded, increasing the in-cylinder positive pressure during the compression and power strokes. This prevents the variable-compression-ratio mechanism (2) from increasing the compression ratio when control is lost.

摘要： An apparatus is provided for controlling an intake valve of a vehicular internal combustion engine. The apparatus includes a variable valve operating mechanism configured to vary a valve lift and a valve phase angle of the intake valve, and a controller. The controller calculates a desired first target value at a current engine operating condition, a reacceleration estimated value based on an engine rotational speed and estimated operating load upon reacceleration, and a second target value at which engine torque is equivalent to engine torque at the first target value. The controller sets the first target value as a control target value, and then switches the control target value to the second target value when a minimum clearance between the intake valve and a piston is determined to become less than a permissible value during variation of the intake valve from the first target value toward the reacceleration estimated value.
