Title: AN IGNITION METHOD AND A SYSTEM THEREOF
Abstract:
The present subject matter provides an ignition system (200) for an internal combustion engine (125). An electrical machine (125E) functionally coupled to a rotating member (125B) of the internal combustion engine (125). An ignition control unit (225) initially enables triggering of the ignition means (250, 255) at a first angle of the rotating member (125B). An engine speed is calculated and is compared with a first reference speed. The ignition control unit (225) modifies triggering of the ignition means (250, 255) at a second angle depending on the engine speed. The ignition control unit (225) subsequently checks the engine speed and modifies triggering of the ignition means (250, 255) at a third angle upon detection of the engine speed being less than a second reference speed, which is less than the first reference speed.
