Class Information
Number: 123/358
Name: Internal-combustion engines > Engine speed regulator > Having condition responsive means with engine being part of a closed feedback system (e.g., cruise control) > Electrical sensing or regulating > Engine speed sensing having an error signal producing circuit > Electric fuel injection pump governor > Max-min governor (i.e., no control in between)
Description: Subject matter in which the circuit output regulates the fuel injection pump output to maintain a minimum engine speed and prevent engine speed from exceeding a maximum value.
