    摘要: In the thermal process air flow meter according to the invention first, second and third electrode terminals are arranged on the same surface at one end of a substrate. A first exothermic resistor is connected between the first and second terminals, and a second exothermic resistor is connected between the second and third terminals, with the first exothermic resistor on a front surface of a substrate and the second exothermic resistor on the opposite (back) surface. The substrate may also carry the semiconductor elements of an electronic circuit used to analyze electric signals from the terminals. In a preferred embodiment of the invention, the substrate is mounted at an incline relative to the direction of unobstructed air flow in the air passage.

    摘要: The air meter forming part of the air intake passage of the engine is equipped with an electronic circuit for measuring the rate of intake air and a memory for storing data pertaining to actual air flow rate versus output characteristics of the air meter or correction data for calculation of air flow rate. The engine control unit digitally calculates actual air flow rate to be used for determination of the amount of fuel to be supplied from a signal output from the air meter with reference to the air flow rate versus output characteristics of the air meter or air flow correction data fetched from the memory provided on the air meter body.

    摘要: An air flow meter comprises an air velocity measuring resistor and a temperature compensating resistor and is installed in a bypass passage provided at an intake passage running through an air horn. The air velocity measuring resistor and the temperature compensating resistor are supported by lead wires whose portions exposed in the bypass passage have the same length. A cover forming the bypass passage is made of heat insulating synthetic resin material to prevent heats from being transmitted to the resistors.
