Class Information
Number: 123/352
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
Description: Subject matter in which the regulator employs a specific type or design of circuit to (a) compare the actual engine speed with a desired or preset speed, and (b) produce an output signal when the two speeds are unequal.
