Control system for supercharger in internal combustion engine

Patent ·
OSTI ID:6802896

A control system for an internal combustion engine having a supercharger is described comprising: an internal combustion engine which emits exhaust gases; a supercharger operable by the exhaust gases emitted from the internal combustion engine and having a rotary shaft; a motor/generator disposed on the rotary shaft of the supercharger; electric power detecting means for detecting the output from the motor/generator and for generating an electric power output signal; fuel supply means for supplying fuel to the internal combustion engine; a flow rate sensor for detecting the rate of fuel flow and for generating a flow rate signal indicative of the detected rate of fuel flow; a rotation sensor for detecting rotation of the internal combustion engine and for generating a rotation detection signal; means for determining whether the motor/generator should operate as a motor or a generator based on the flow rate signal and the rotation detection signal; and means for controlling the rate of fuel flow to the internal combustion engine based on the electric power output signal.
