DEFINITION

Classification: 123/406.46

Acceleration or deceleration responsive:

Subject matter under subclass 406.45 wherein the regulating means to vary spark ignition timing 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.
