    摘要： @ An air flow meter circuit with a temperature compensation circuit comprises an air flow rate detection circuit (20; 200) for generating an output signal (V 2 ) in accordance with an air flow rate, an output circuit (30; 300) for amplifying the output signal of the air flow rate detection circuit to produce an output signal (V o ) whose value is so adjusted as to be related to the value of the input signal in a predetermined relationship, and a constant voltage circuit (10; 100) for supplying a predetermined reference voltage to the air flow rate detection and output circuits. In order to compensate the output of the air flow meter circuit for its changes due to the influence of temperature coefficients of component parts of both the air flow rate detection and output circuits, the temperature coeffcient of the output of the constant voltage circuit (10; 100) is so adjusted as to cancel out the temperature coefficients of the parts constituting the airflow meter circuit.

    摘要： A knock control apparatus for internal combustion engines includes a plurality of sensors (4 - 8) for generating signals indicative of the operating conditions of an engine, a plurality of actuators (26, 28) responsive to control signals to control the respective energy conversion functions of the engine, a data processing unit (12) responsive to the signals from the sensors (4 - 8) to perform engine controlling data processing operations and thereby supply engine control values to the actuators (26, 28), and a knock sensing unit (2, 10) for detecting the occurrence of knocking in the engine and generating knock detection signals, and the data processing unit (12) is responsive to the knock detection signals from the knock sensing unit (2, 10) to retard the calculated ignition timing. When the acceleration of the engine is detected in accordance with the output signal of the sensor, the data processing unit increases, in accordance with the knock detection signals, an amount of ignition timing retard to be calculated over an amount of retard to be calculated in accordance with the knock detection signals during the steady operation of the engine.
