Abstract
A system includes an electronic fuel injection system of an engine, the electronic fuel injection system including an electronic governor control unit for controlling various functions of the engine.
Claims20
A method for automatically learning throttle position, comprising:
- monitoring a throttle position sensor voltage signal sent by a throttle position sensor to an electronic governor control unit, the throttle position sensor voltage signal representing a position of a throttle;
- measuring a run time of an engine via a timer;
- filtering the throttle position sensor voltage signal based on a value of the timer;
- and
- saving a lowest measured value of the throttle position sensor voltage signal and assigning the lowest measured value to a zero percent throttle.

A method for automatically learning throttle position, comprising:
- monitoring an age of an engine with a timer;
- monitoring a throttle position sensor voltage signal sent by a throttle position sensor to an electronic governor control unit, the throttle position sensor voltage signal representing a position of a throttle;
- removing unwanted voltage spikes with a digital or analog filter, the digital or analog filter having an attenuation which increases with increasing age of the engine;
- and
- saving a lowest measured value of the throttle position sensor voltage signal and assigning the lowest measured value to a zero percent throttle.
