摘要： An object of this invention is to prevent a diaphragm of an actuator from being damaged by a high temperature, and improve a heat resistance property of the actuator. A valve actuator includes a communication hole that allows communication between a high pressure chamber and a low pressure chamber that are separated by a diaphragm, and a normally closed reed valve that opens and closes the communication hole. When a temperature of the valve actuator is less than a pressure release temperature, an ECU changes a differential pressure between the high pressure chamber and low pressure chamber by means of a pressure regulating valve, to control the valve actuator. This control is executed within a range of differential pressures at which the reed valve does not open. If the temperature exceeds the pressure release temperature, a differential pressure at which the reed valve opens is realized by the pressure regulating valve. Thus, pressure is released from the high pressure chamber to the low pressure chamber at a high temperature, and the diaphragm can be protected.
摘要翻译： 本发明的目的是防止致动器的隔膜被高温损坏，并提高致动器的耐热性。 阀致动器包括连通孔，该连通孔允许由隔膜隔开的高压室和低压室之间的连通，以及打开和关闭连通孔的常闭簧片阀。 当阀致动器的温度小于压力释放温度时，ECU通过压力调节阀改变高压室和低压室之间的压差，以控制阀致动器。 该控制在簧片阀不打开的差压范围内执行。 如果温度超过压力释放温度，则由压力调节阀实现簧片阀打开的压差。 因此，在高温下将压力从高压室释放到低压室，并且可以保护隔膜。

摘要： A turbine of a turbocharger is disposed on an exhaust passage. An air-fuel ratio sensor is disposed downstream of and in proximity to the turbine. An element of the air-fuel ratio sensor is positioned on or near the axis of an exhaust port of the turbine. A whirling flow of an exhaust gas in the same direction as a turbine wheel rotates is produced immediately after the exhaust port of the turbine, so that the whirling flow of the exhaust gas can centrifuge condensed water in the exhaust gas. The exhaust gas contacts the element near the axis of the exhaust port where there is substantially no condensed water, thus preventing the element from being wetted with water or cracked.

摘要： An ECU calculates a target working angle r, and determines a difference between the target working angle r and the previous value r′ of target working angle as a change rate v to be feedforward controlled. Further, the ECU determines a deviation to be corrected by feedback control from the target working angle r and an actual value that is input from a sensor as a hypothetical rate u. The change rate v and the hypothetical rate u are added together, and a control amount to be output, for example, a voltage E is determined by referring to a three-dimensional map M3 from the added set change rate (v+u) and the input target working angle r.

摘要： A control system for an internal combustion engine calculates a provisional target value of the throttle opening in accordance with an accelerator pedal travel, upon detection of a sudden operation of the accelerator pedal. The system also calculates a target pressure change in the surge tank according to the provisional target value, on the basis of the actual surge tank pressure and the cylinder intake mass airflow, using a virtual intake system model. The control system sets a target throttle opening in accordance with the surge tank pressure and the cylinder intake mass airflow, so as to provide the target pressure change under a condition of the actual surge tank volume.

摘要： In an internal combustion engine with a supercharger, there is provided a technique capable of quickly raising supercharging pressure. In the internal combustion engine with a supercharger which includes a communication passage 6 that connects between those portions of an exhaust passage 3 which are upstream and downstream of an exhaust gas turbine 4c of the supercharger 4, and a waste gate valve 7 that is arranged in said communication passage 6 so as to open from an upstream side of said communication passage 6 to a downstream side thereof, provision is made for a drive unit that applies a fixed force directed from the downstream side to the upstream side of said communication passage 6 to said waste gate valve 7. By applying the fixed force to the waste gate valve 7, said waste gate valve 7 is not opened until a differential pressure between the upstream and downstream sides of the waste gate valve 7 becomes larger than the fixed force, so the supercharging pressure rises smoothly.
