Engine control equipment and its air meter.

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.
