Electronic engine control compensator

Abstract

Abstract PURPOSE:To make variations in an engine no-load characteristic absorbable, by calculating an operating angle of a driving lever to the specified rotational frequency of an engine, learning and storing it in memory, while finding the driving lever's operating angle by this stored value, and controlling this driving lever. CONSTITUTION:In a control unit 22, when a fact that an engine is started by a gear in neutral is discriminated, whether a learning start switch 26 is turned on or not is judged. And, when it is judged to be switched on, an engine no-load characteristic map, where plural data of a driving lever operating angle are conformed on plural engine speed ranges prestored in a random access memory of the control unit 22, is retrieved whereby the driving lever operating angle conformed to the current engine speed is calculated. Next, according to this calculated operating angle, a step motor 21 is driven, and an engine speed compensating driving lever 5 is optimally controlled.
