DEFINITION

Classification: 123/406.36

Acceleration or deceleration responsive:

(under subclass 406.35) Subject matter wherein the regulating means is responsive to a sudden demand for either (a) an increase in the power or torque output of the engine or (b) a decrease in the power or torque output of the engine.

(1) Note. Acceleration or deceleration may be indicated by the rate of change of engine speed or load.
