    摘要: Disclosed is an internal combustion engine control device that is capable of accurately estimating a turbine flow rate during a transient operation of an internal combustion engine with a turbocharger having a WGV. Steps are performed to acquire an exhaust gas flow rate mcyl (=mB), a WGV opening WG (=X), and a turbine rotation speed Ntb (=Na) during the transient operation of the internal combustion engine. Steps are then performed to calculate the turbine flow rate (=mtA) and exhaust gas flow rate mcyl (=mA), which prevail when the turbine rotation speed Ntb and WGV opening WG acquired during the transient operation are achieved during a steady operation. Next, a step is performed to calculate the turbine flow rate (=mtB) during the transient operation by applying the flow rate ratio of mtA to mA to the exhaust gas flow rate mcyl during the transient operation. Preferably, the turbine rotation speed Ntb during an Ntb transient operation is estimated by using a turbine flow rate change amount Δmt (=mtB−mtA) during the transient operation.

That control system has a device inhibiting the operating timing from being returned in a direction reverse to the direction of the target operating timing during change of the operating timing. Further, in the control system, the relative rotational phases of the valve drive cam and the pump drive cam are set considering utilization of the composite reaction torque of the valve operation drive reaction torque and the fuel pump drive reaction torque acting on the valve camshaft for changing the operating timing in the direction of the target operating timing.

    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.

    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.
