RESEARCH TO DETERMINATE THE LAW OF OPTIMUM IGNITION TIMING ON ENGINE SKYACTIV-G 2.0 MAZDA 6

Abstract

The ESA (Electronic Spark Advance) system is a system that uses the engine ECU to determine the ignition timing based on the signals from the various sensors. The engine ECU calculates the ignition timing from the optimum ignition timing stored in memory to match the engine conditions, and then sends the ignition signal to the igniter. The optimum ignition timing is basically determined using. The ESA system consists of the various sensors, engine ECU, igniters, ignition coil, and spark plugs. Due to the characteristics of mixture and combustion technology, the design and programming of the ignition control program for direct injection engines is very complicated. In general, the design and manufacture of ECUs in general and ECUs for direct injection engines in particular are still quite new in Vietnam. The article aims to analyze the characteristics, working principles and build an experimental process on the GDI direct injection engine ignition system. The article is a synthesis of experimental results and research to determine the control rule of early ignition angle on Skyactiv-G 2.0 engine in Mazda 6.
