Abstract

Content: A Karman vortex airflow sensor has been developed and adopted to a new electronically controlled fuel injection system, named ECI, of Mitsubishi Motors' 1.8 and 2.0-liter naturally aspirated and turbocharged engines. The sensor consists of an air channel with a triangular strut to generate the Karman Vortex Street, a couple of ultrasonic transmitter and receiver to detect the vortexes, and a control unit using custom designed ICs.

This paper presents the principle, the construction and characteristics of the sensor.
