A electric control engine and method for correcting fuelling map automatically in the engine

摘要

PURPOSE: An electronic control typed engine and a controlling method of a fuelling map are provided to perform a complete fuelling through compensating the fuelling map according to difference in potentiometer value. CONSTITUTION: An ignition switch is turned on for driving an ECM(Engine Control Machine). By a driver stepping on an accelerator pedal, an idle checking switch is transferred from an idle position to an acceleration position. Thus, the ECM receives an on signal of the idle checking switch to decide operation of the accelerator pedal. The ECM receives a signal from a variable resistance for storing in an inner memory for a specific time. Then, the ECM reads the variable values from the memory for detecting a minimum value and a maximum value. The minimum value and the maximum value are compared with a potentiometer of an established fuelling map. In case of stored values under the established potentiometer, the ECM compensates the fuelling map.
