    摘要: In an exhaust gas recirculation system for an internal combustion engine, a flow control valve is disposed within a recirculation pipe and operatively connected to a pneumatically operated servomotor to control the flow quantity of exhaust gases through the recirculation pipe, and an orifice is disposed within the recirculation pipe upstream of the valve to form a space between the valve and the orifice. A pressure regulator serves to modulate negative pressure from an engine intake manifold to the servomotor on a basis of pneumatic pressure applied thereto and pressure in the space. The pneumatic pressure applied to the pressure regulator is electrically controlled to satisfy the following equation.Pd=f(Pv, N)where the character Pd is the pneumatic pressure applied to the pressure regulator, and the characters Pv and N respectively indicate the negative pressure in the intake manifold and the engine speed.

    摘要: An apparatus for controlling an ignition coil of internal combustion engines including a power transistor connected to the primary winding of an ignition coil for controlling the energization and deenergization of the primary winding in response to a signal applied to the base of the power transistor. A feedback circuit, including a constant voltage diode, a capacitor and a resistor, is connected between the collector and base of the power transistor. When the power transistor becomes conductive from a nonconductive condition, a collector current of the power transistor flows through the capacitor and constant voltage diode due to the Miller integrator effect and the transition from nonconduction to conduction of the power transistor is made gradual thereby reducing a voltage generated in the secondary winding of the ignition coil.On the contrary, when the power transistor becomes nonconductive from the conductive condition, the constant voltage diode is rendered conductive due to a high voltage generated at the collector of the power transistor to allow a base current to flow and in turn to allow a collector current thereby preventing breakdown of the power transistor.

    摘要: The timing of spark ignition is set in normal operating conditions at a programed spark advance angle corresponding to the MBT (minimum spark advance for best torque). When knocking of the engine is detected by a vibration sensor, the ignition timing is delayed by a predetermined amount, e.g., 2.DELTA..theta., for each engine cycle that knocking is detected in synchronism with the rotation of the engine. When knocking is not detected, the ignition timing is advanced by another predetermined amount, for each engine cycle that knocking is not detected. e.g., .DELTA..theta.. In this method for controlling the spark timing, the amount of retardation, 2.DELTA..theta., is selected to be larger than the other amount of advance, .DELTA..theta..
