Abstract
A throttle-valve most closed position sensing system is disclosed for use with an internal combustion engine. The system includes a throttle position sensor for providing a signal indicative of the degree of opening of the associated throttle-valve. A decision circuit is provided for deciding throttle-valve position as the most closed position when receiving a throttle-valve position indicative signal smaller than or equal to the smallest signal having received from the throttle position sensor.
Claims6
A throttle-valve most closed position sensing system for use with an internal combustion engine having an induction passage provided thereinwith a throttle valve, said system comprising:
- (a) a throttle position sensor for providing a signal proportional to the degree of opening of said throttle valve;
- and
- (b) a decision circuit for deciding throttle-valve position as the most closed position when receiving, from said throttle position sensor, a signal smaller than or equal to the smallest signal having received therefrom.
A throttle-valve most closed position sensing system for use with an internal combustion engine having an induction passage provided therein with a throttle valve, said system comprising;
- (a) a throttle position sensor for providing a signal inversely proportional to the degree of opening of said throttle valve;
- and
- (b) a decision circuit for deciding throttle-valve position as the most closed position when receiving, from said throttle position sensor, a signal larger than or equal to the largest signal having received therefrom.
