摘要： A method of controlling supercharging pressure in an internal combustion engine having a supercharger with an increase rate-varying device for varying the rate of increase of the supercharging pressure. The supercharging pressure is controlled to a desired value in response to the difference between the actual value of the supercharging pressure and the desired value. The increase rate-varying device is held in a position for obtaining the maximum rate of increase of the supercharging pressure while the actual value of the supercharging pressure is below a predetermined value which is lower than the desired value. The predetermined value is set to a lower value as the rate of increase of the supercharging pressure increases, or when a transmission of the engine is in a lower of two or more speed positions of the transmission. Also, the predetermined value of the supercharging pressure is set to a lower value as the actual intake air temperature decreases.

摘要： A method of controlling supercharging pressure in an internal combustion engine, wherein the supercharging pressure is controlled by controlling a control amount for operating a supercharging pressure control device. The control amount is controlled in feedback control mode responsive to the difference between the actual value of the supercharging pressure and a desired value thereof when the supercharging pressure is in a steady state, and at the same time a learned value of the correction value is obtained by calculating values of same applied during the feedback control. The control amount is controlled in open loop control mode based upon the learned value when the supercharging pressure is in a transient state. The calculation of the learned value is inhibited when a predetermined condition is satisfied during the steady state. The predetermined condition is satisfied when the desired value of the supercharging pressure is set to a different value than a normal value set during the steady state.

摘要： A method of controlling supercharging pressure in an internal combustion engine by means of a basic control amount dependent upon operating conditions of the engine. A change rate of the supercharging pressure is detected. When the supercharging pressure is in a transient state where it is increasing, the basic control means is corrected in response to the detected change rate of the supercharging pressure, in such a manner that the supercharging pressure increases at a predetermined rate.

摘要： An engine control system comprising a variable valve actuating mechanism for an engine which may consists of a mechanism capable of varying valve timing, a variable capacity supercharger which may consists of a turbocharger provided with moveable vanes for varying a cross sectional area of an exhaust gas passage leading to a turbine wheel, and a control unit for controlling a valve actuating operation of the valve actuating mechanism and a capacity varying operation of the variable capacity supercharger. The capacity of the supercharger is controlled by taking into account the operating conditions of the valve actuating mechanism. Thus, the control unit is capable of achieving a precise and prompt control action, and, by appropriately determining the control plan, it is possible to increase the maximum output of the engine and/or to reduce strain on the engine.

摘要： A driving wheel slip control system installed in a vehicle and having abnormality-detecting and failsafe functions. The system includes a slip status signal-generating device for generating a slip status signal indicative of whether or not the driving wheels of the vehicle are in a predetermined slip state, and a slip level signal-generating device for generating a slip level signal indicative of a degree of slip of the driving wheels. If a logical relationship between the slip status signal and the slip level signal is abnormal, and if the prime mover for driving the driving wheels is not accelerating and at the same time the slip level signal indicates the predetermined slip state, the slip level signal is determined to be abnormal. If an abnormality is detected during driving wheel slip control, an amount of reduction in output of the driving wheels is set to a predetermined amount to thereby continue driving wheel slip control, until the prime mover enters an operating condition other than acceleration. Further, the system comprises first and second control units. The latter informs the former of three states for determining whether or not driving wheel slip control can be carried out. The first control unit has the slip level signal-generating device and the slip status signal-generating device, and inhibition of operation of these devices is retarded when it is informed of a state inhibiting driving wheel slip control, if an excessive slip state of the driving wheels is occurring.

摘要： A misfire-detecting system detects a misfire occurring in an internal combustion engine. A value of sparking voltage for discharging a spark plug of the engine is detected. The detected value of the sparking voltage is compared with a first predetermined value. A degree to which the detected value of the sparking voltage exceeds the first predetermined value is measured. The measured degree is compared with a second predetermined value. It is determined based upon results of the latter comparison whether or not a misfire occurred in the engine. According to a first aspect of the invention, the second predetermined reference value is set based upon detected values of operating parameters of the engine. According to a second aspect of the invention, the determination of occurrence of a misfire is inhibited when the engine is in a predetermined operating condition.

摘要： A system for controlling a boost pressure in an internal combustion engine is equipped with a turbocharger. Engine operation is divided into three regions based on an engine speed with respect to an engine load. Throughout the regions, a target boost pressure is predetermined to be considerably lower than a level at which knock frequently occurs. In the region where the engine speed and load are relatively high, the target boost pressure is gradually raised until knock occurs. When knock occurs, the target boost pressure is fixed at a value slightly lower than the value at which knock has occurred and thereafter the boost pressure is controlled to the fixed target pressure.
