The Effectiveness of Using Heaters on Mufflers to Reduce Exhaust Emissions from Spark Ignition Engines

Abstract

The increasing population of motor vehicles can result in increased levels of exhaust emissions. The most significant contributor to exhaust emissions comes from motor vehicle exhaust. This study aims to reduce exhaust emissions, which will have an impact on reducing air pollution caused by motor vehicle exhaust gases. This research method is quantitative descriptive experimental with exhaust gas emission testing standards based on SNI 19-7118.3-2005. The test results show that the use of a heater in a Yamaha New Vixion Lighting motorcycle exhaust can reduce exhaust emissions CO and HC. By using an experimental exhaust one heater, it can reduce CO exhaust emissions by an average of 27.74%, and HC exhaust emissions by an average of 5.55. Whereas using experimental exhaust two heaters can reduce CO exhaust emissions by an average of 35.02%, and HC exhaust emissions by an average of 16.31.
