摘要： PURPOSE:To enhance the output torque as well as relieve the setting of air-to- fuel ratio on the rich side, by starting water flush in the event of knocking, and by reducing the rate of fuel injection by an amount corresponding to this water flush. CONSTITUTION:While a supercharger is in operation and knockings are generated in the engine, a water flush calculating means calculates the rate of water flush according to the engine output air-to-fuel ratio, and meantime a water flushing means sprays the water at the calculated rate into the engine. At the same time, No.1 rate-of-fuel-injection calculating means calculates the rate of fuel injection so as to provide the engine output air-to-fuel ratio. Thus the output torque is enhanced as well as the setting of air-to-fuel ratio on the rich side can be relieved.

摘要： PURPOSE:To contrive an improvement in drivability by enabling fuel injection corresponding to the sudden change of an operation state, by a method wherein a plurality of times of fuel injection operations is performed during suction stroke period of each cylinder synchronously with an engine speed and fuel is made to inject every operation. CONSTITUTION:During operation of an engine, a cut-in step is made to perform every generation of a crank angle signal (45 deg.CA in case of 4 cylinder engine), a basic injection quantity TD is computed through data Q of a suction quantity by an air flow meter 11 and data Ne of a speed, which is made into an injection quantity T by correcting the same according to an operation state of the engine, in a control circuit 10. Then discriminating counter value of a cylinder during a suction stroke is read out from a memory for decision, and fuel is made to inject toward a suction port of the corresponding cylinder by energizing any one of fuel injection valves 5-1-5-4 according to a result of the discrimination. Then each injection valve is controlled in order in conformity with a fuel injection quantity computed every time by performing the above action every generation of a crank angle signal.

摘要： PURPOSE:To effectively perform purification of exhaust gas with the use of a catalyst while maintaining the intrinsic performance of a turbocharger, by regulating a passage valve by means of the temperature of an exhaust gas purifying catalyst and pressure of the air exhausted from a compressor chamber. CONSTITUTION:If the temperature of a catalyst 17 is below a given value, a hydraulic switching valve 23 interconnects an oil pressure introducing port 26 and a first oil port 24 or a pressure bleed port 27 and a second oil pressure port 25. An actuator 100 drives a rod 104 to rotate a passage valve 18 to the outlet passage 20 side so as to close this valve. When the temperature of the catalyst 17 exceeds the given value, the hydraulic switching valve 23 is changed over so that the passage valve 18 may be rotated to the bypass passage 21 side through driving of the rod 104, and the valve is closed. When the pressure of the air exhausted from a compressor chamber 4 exceeds a given value, a third pressure chamber 103 is increased in its pressure to displace the rod 104, and the passage valve 18 slightly releases the bypass passage 21 to reduce the number of revolution of a turbocharger 1 and control a supercharger.

摘要： PURPOSE:To improve an acceleration characteristic in an engine, by injecting an equal amount of fuel to that of fuel, obtained for its injection into a cylinder, simultaneously into the next cylinder for fuel to be injected so as to correct acceleration fuel, at acceleration of the engine when a change amount of intake air per one revolution of the engine exceeds the predetermined value in the increase direction. CONSTITUTION:During operation of an engine, a computer 9, obtaining an intake air amount Q/N per one revolution of the engine from a signal Ne of a crank angle sensor 7 and an intake air amount signal Q of an air flow meter 10, determines a basic injection amount of fuel. Next, the computer 9 both corrects the basic injection amount of fuel by the other signal of engine operative condition and discriminates a cylinder for fuel to be injected by signals of the crank angle sensor 7 and a cylinder discriminating sensor 8. Then in this case, at acceleration when a change rate DELTAQ/N of the intake air amount Q/N per one revolution of the engine exceeds the predetermined value, an equal amount of fuel to that of fuel, being injected into and metered for a cylinder (a), is simultaneously injected into the next cylinder (b), serving as an acceleration increase of fuel for the cylinder (b).
