摘要： A fuel supply control system for internal combustion engines properly controls the additional fuel supply at high speed operation and full load operation of the engine without causing overheating of the exhaust gas purifying device of the engine. The fuel supply control system includes a throttle switch for generating a load detection signal when the throttle valve is at its substantially full open position indicative of the heavy load condition of the engine and includes a high speed detecting device for generating a high speed detection signal when the amount of air sucked into the engine or when the intermittent signals from an ignition device exceeds a predetermined amount. In response to at least one of the detection signals, the additional fuel is supplied to the engine.

摘要： In an air-to-fuel ratio feedback control system of the type in which the output detection signal of an air-to-fuel ratio detector adapted to detect the concentration of an exhaust gas constituent of an internal combustion engine is compared with a preset value in a comparison circuit whose output signal in turn is utilized to feedback control the air-to-fuel ratio of mixture supplied to the engine, the preset value of the comparison circuit is changed to another value in response to the occurrence of a condition which requires the stopping of the feedback control of the air-to-fuel ratio of mixture supplied to the engine, thereby preventing the occurrence of malfunction during transient periods such as the periods of opening and closing of the feedback control system loop.

摘要： An O2 amount in the intake air is determined based on a fresh air and an EGR gas. A consumed O2 amount is determined with a command injection amount Qr. Then, the consumed O2 amount is subtracted from the O2 amount in the intake air to obtain an exhaust O2 amount. An exhaust O2 concentration is estimated based on the exhaust O2 amount. According to the invention, the system is not affected by a delay for the exhaust gas to reach an O2 sensor and a delay of the chemical reaction in the O2 sensor. Therefore, the exhaust O2 concentration can be highly precisely estimated compare to the case in which the exhaust O2 concentration is detected by the O2 sensor.

摘要： In a fuel infection valve, a valve chamber of a three ways valve is selectively communicated to drain and high pressure conduits and also communicated, via a main orifice, to a control chamber for controlling valve opening and closing operations of a nozzle needle. The control chamber may be communicated via the main orifice and the valve chamber to the drain conduit or the high pressure conduit, when a valve body is driven by a piezo actuator to open or close the drain conduit and close or open the high pressure conduit. The control chamber is always communicated via a sub orifice to the high pressure conduit without bypassing the three ways valve. Accordingly, hydraulic pressure in the control chamber is slowly decreased at a valve opening time and is rapidly increased at a valve closing time so that a lift characteristic of the nozzle needle is improved.

摘要： An air-fuel ratio control apparatus for an internal combustion engine which is equipped with an air-fuel ratio sensor for sensing an actual air-fuel ratio of a mixture to be introduced into the engine and a target air-fuel ratio setting section for setting a target air-fuel ratio of the engine. Also included is a controlled-amount calculating section for setting an optimal feedback gain on the basis of a predetermined dynamic model of the engine to calculate a controlled amount in accordance with the predetermined optimal feedback gain so that the actual air-fuel ratio becomes equal to the target air-fuel ratio. A fuel supply amount to the engine is determined on the basis of the calculated controlled amount, and the control responsiveness of the controlled-amount calculating section is suppressed when the engine is in a speed-decreasing state. This arrangement can adequately control the air-fuel ratio of the engine irrespective of the engine speed-decreasing state.
