摘要： A system for controlling the operating condition of an engine in which a temperature sensing element constitutes an airflow measuring device disposed in an intake air passage of the engine. The temperature sensing element is supplied with a heating current in response to a start pulse signal produced with every one-half period of each combustion cycle of the engine. A comparator delivers an output signal when a reference temperature set on the basis of the air temperature measured by an auxiliary temperature sensing element is reached by the temperature of the temperature sensing element. A pulse signal indicative of the time interval between the generation of the start pulse signal and a rise in the output signal of the comparator is delivered as an airflow measurement signal. The average airflow quantity responsive to one combustion cycle of the engine is detected, and a correction factor K is calculated from the difference between two airflow rate data measured in each combustion cycle and the average airflow quantity. Based on the correction factor K, the injection quantity, injection timing and the like are calculated.

摘要： A control system for an engine has a temperature sensitive element as part of a device for measuring the air flow in an air intake manifold to the engine. Further, a first pulse signal is generated, corresponding to the rotation of the engine, for controlling the setting of a flip-flop. A transistor is conducted in the set state of the flip-flop to supply a heating electric current to the element. The element supplied with the current is raised to the temperature that corresponds to the air flow in the manifold. When the temperature of the element is raised until the specified temperature difference to the air temperature (measured by a sub temperature sensitive element) is set, the temperature difference is detected by a comparator, and the flip-flop is reset by the detection signal. A pulse-shaped signal corresponding to the set state of the flip-flop is produced as a measurement output signal, supplied as one detection signal of the operating state of the engine to an engine control unit, and the current to the element is controlled to be supplied by the pulse-shaped signal.

摘要： Fuel injection modes including an independent injection mode, group injection mode and simultaneous injection mode are changed over in accordance with an engine operating condition, for example, a load condition. The independent injection mode is selected when the engine is operating in a low load condition, and the fuel injection timing for each cylinder is controlled independently. When the low load condition of the engine changes to an intermediate load condition, the group injection mode is selected and the fuel injection timing is controlled for each group of cylinders formed by grouping the cylinders into at least two groups. The simultaneous injection mode is selected when the intermediate load condition changes to a high load condition, and the fuel injection timing for all the cylinders is controlled to be simultaneous.

摘要： The amount of secondary air flowing through a bypass air passage bypassing the throttle valve of an engine, which is connected to an automatic transmission of a vehicle having an air-conditioner, is controlled by an air control valve disposed in the bypass air passage. The air control valve is controlled on the basis of the result of comparison between a signal indicative of the actual idling rotation speed of the engine detected by the distributor of the engine and a reference signal indicative of a desired idling rotation speed of the engine. The level of this reference signal indicative of the desired idling rotation speed of the engine varies depending on the on-off of the air-conditioner in the vehicle or on the position of the shift lever of the automatic transmission.

摘要： A system for controlling the amount of air taken in by an engine comprises an air duct tube bypassing a throttle valve of an intake tube for taking in air supplied to an automobile engine, a plurality of valves for regulating the amount of air passing through the air duct tube, and control device therefor. The amount of air in the bypass is controlled in accordance with the temperature and number of revolutions of the engine and the air intake pressure downstream of the throttle valve. During the idling of the engine, the air intake control system generates a signal representing the standard engine idling revolutions in accordance with the engine temperature, compares the actual engine revolutions with a reference, and regulates the amount of air flowing in the bypass by use of the results of a comparison, thus rendering the actual engine revolutions identical to the reference. During the loaded engine operation, by contrast, the amount of bypass air is so controlled that the air intake pressure downstream of the throttle valve is maintained at predetermined constant value.

摘要： Spark ignition timing of an internal combustion engine is oscillated on each side of a variable reference setting by varying it at stepwisely variable amounts during positive and negative swings and the resultant engine speed is detected in at least three successive phases.

The variable reference is adjusted in a direction toward an optimum position depending on which one of the conditions is satisfied.
