Theoretical investigation of engine performance and exhaust emissions in ethanol-fueled dual-plug SI engine
Abstract
Most of the on-road vehicles with two and four wheels have spark-ignition (SI) engines. Investigations on SI engine performance and exhaust emission characteristics are still valuable due to environmental reasons. This study, therefore, investigated the effect of equivalence ratio, spark timing, and spark-plug location on engine performance and exhaust emission characteristics in an ethanol-fuelled dual-plug SI engines by using a theoretical model. Findings showed that dual-spark plug configuration (SpL@d) in an SI engine is the convenient solution to continue superior engine performance and exhaust emission characteristics if there are some design constraints in contrast to the centrally located single plug (SpL@c) configuration giving the best engine performance and fuel economy.
