INTAKE DEVICE FOR INTERNAL COMBUSTION ENGINE AND METHOD OF MEASURING INTAKE AIR AMOUNT

摘要

An intake device for an internal combustion engine has a restriction valve provided in an air intake path of the engine and has an air flow rate sensor provided on the downstream side of the restriction valve and measuring the amount of air sucked into the air intake path. The air flow rate sensor has an air flow path where a sensor element is provided. The air flow path is set in the air intake path with a predetermined angle between the axis of the air flow path and the axis of the air intake path.
