DEFINITION

Classification: 123/394

By combustion air or air-fuel mixture cutoff:

(under subclass 349) Subject matter wherein the flow of the engine's intake air or air-fuel mixture is throttled or cutoff by a valve means in the engine intake (other than the engine throttle) acting in response to engine speed.

(1) Note. The valve means may itself sense the engine rpm by responding to airflow rate.
