DEFINITION

Classification: 123/406.23

Engine output (e.g., torque, speed, horsepower) or fuel consumption optimization:

(under subclass 406.19) Subject matter wherein the regulating means responds to a signal indicative of either (a) the power or force produced by the internal combustion engine, or (b)

the rate at which the combustible material is burned, and (c) continuously varies the spark ignition timing to obtain either (1) the best attainable power or force produced by the engine, or (2) the best rate, for a given set of conditions, at which the supply of the combustible material is used.
