The Effect of Ignition Timing on Methanol Blended Spark Ignition Engine

The objective of the present work is to evaluate whether variable ignition timing can be effect on exhaust emission and engine performance of a spark ignition engine. The study describes some results of research in the area of spark ignition engine and is assessed by studying its performance and emission characteristics relative to that of conventional ignition engine using gasoline and methanol blended gasoline as fuels at different ignition timings. Experiments were conducted at different ignition timings. The results have shown that performance of methanol blended gasoline engine performed comparatively well over pure gasoline engine fewer than 25 0 to 29 0 BTDC ignition timings. The results have shown considerable performance improvement in brake thermal efficiency, volumetric efficiency, decrease in exhaust gas temperature, as well as reduction in HC, and CO emission.
