Implementation and Tests of a Variable Control System of Spark Time Ignition, using Digital Signal Processor - DSP 2004-01-3441
Electronic management system applied to Automotive Engineering is able to optimize the operation parameters for an Internal Combustion Engine (ICE) increasing their efficiency. The development of those systems is a multidisciplinary task that involves specialists from different areas that use, among other resources, high performance digital computers. The objective of this work is to present the implementation of a new variable control system of spark time ignition, controlled by computer, that uses a Digital Signal Processor (DSP) to optimize the spark advance curves of ICE's during the development in engine test bed. This work presents the implementation of the variable spark time ignition system and the comparative results, obtained during the development tests in dynamometer, between the implemented system and the original engine management used in the tests.
