摘要： A closed-loop emission control apparatus for internal combustion engines includes exhaust composition sensor for feedback control of the air-fuel mixture. When the temperature in the exhaust passage is lower than the operating temperature of the sensor, control is switched to an open-loop mode. The feedback control signal is fluctuated above and below a predetermined DC bias at periodic intervals during the open-loop mode to switch the control to the closed-loop mode in a minimum transition time as soon as the sensor's temperature condition warrants feedback control.

摘要： Emission control apparatus for internal combustion engines is provided with a sensor for detecting the concentration of a particular exhaust composition in the emissions from the engine. A signal indicating the deviation of the mixture ratio from a controlled point is generated by comparing the output from the sensor with a reference level, the signal being modified in amplitude according to a predetermined control characteristic and used to regulate the air-fuel mixture ratio at the desired control point. The varying magnitude of the sensed concentration is smoothed into a signal of slowly varying magnitude which is used to control the reference level so that error introduced into the deviation indicating signal due to the change with time in the output performance of the exhaust composition sensor is self-compensated. A level sensor is provided to detect when the reference level reaches an end of the control range to change the operating mode of the engine from closed-loop to open-loop mode.

摘要： Mixture ratio control for internal combustion engines supplies a constant current into an exhaust gas sensor to develop a voltage of a substantial magnitude in proportion to the initial high value of the gas sensor internal impedance during low temperature conditions. The voltage so developed decreases as a function of time corresponding to the decrease of the internal impedance with temperature. A voltage detector is provided to trigger the control system to operate in a closed loop mode when the gas sensor voltage is reduced to a level below a first threshold level. Responsive to the output of the voltage detector the supplied current is momentarily interrupted to allow the gas sensor voltage to drop rapidly to a level which is higher or lower than a second threshold level depending on the concentration of the sensed gas in the exhaust system. A second detector senses this voltage drop relative to the second threshold to determine whether the gas sensor output represents rich or lean condition. The reference point of the closed loop is raised or lowered in response to the output of the second detector and further decreased as a function of time such that the reference point lies within the range between maximum and minimum peak values of the gas sensor output signal.

摘要： A method and system for correcting engine ignition timing without the use of any pressure sensor or vibration sensor and depending upon engine knocking is disclosed. The presence or absence of knocking is determined by reference to the rate of change of engine speed. This method is based on the fact that engine speed changes abruptly when engine knocking occurs, as compared with the normal engine condition, because of abrupt changes in pressure within the cylinders. The system of the present invention comprises an crankshaft angle sensor to generate a crankshaft angle pulse signal, a period measuring means to output an interrupt request signal and to determine the presence or absence of engine knocking, a microcomputer, and an ignition signal generator for outputting an ignition signal in accordance with an ignition timing signal and a dwell angle signal.

摘要： The spark advance control apparatus of the invention comprises a vacuum advance control mechanism and a speed advance control circuit. The vacuum advance control mechanism senses the vacuum pressure in the intake manifold of an internal combustion engine and generates an electrical pulse in advanced timing in relation to the sensed vacuum. The speed advance control circuit receives the pulse from the vacuum advance control mechanism, converts it into a voltage signal representative of the revolution of the engine crankshaft and generates an output voltage which varies nonlinearly as a function of the voltage signal. A pulse-width generator is provided having a first input connected to receive the pulse from the vacuum advance control mechanism and a second input connected to receive the nonlinear speed related voltage signal to generate a pulse which commences in response to the vacuum advance pulse and ends at a time determined by the speed related voltage signal. The trailing edge of the output from the pulse-width converter is utilized for ignition.

摘要： In an electronic fuel injection system for an internal combustion engine, a throttle position sensor provides an output pulse with a duration corresponding to the time interval during which throttle is nearly closed. The output from the throttle position sensor is nullified when the pulse duration is smaller than a predetermined value to prevent fuel cut-off during brief closure of throttle during transmission gear changes. The output from the throttle position sensor is used to cut off fuel only when the throttle closure time extends beyond the predetermined time interval.
