Description

ABSTRACT:
A turbocharger control device for use in conjunction with an internal combustion engine includes a turbine driven by exhaust gases; a compressor connected with the turbine by having a shaft having a hole through the diameter; a photo projector and photo receiver facing each other across the shaft at the location of the through-hole for generating a light pulse signal proportional to the rate of rotation of the shaft; a photo-voltage converter connected optically with the photo receiver for converting the light pulse signal to an electrical pulse signal; an engine control unit connected electrically with the converter for generating a control signal in response to the electrical signal; an actuator connected with the engine control unit for movement in response to the control signal; an exhaust gas bypass passage connected between upstream and downstream portions of the turbine; and a bypass valve operatively connected to the actuator and associated with the bypass passage for controlling the flow through the bypass passage in response to the control signal.
