Expanded Elbow Pipes and Mufflers: Its Effects on Fuel Consumption of Four Cycle Motorcycle Engine

Abstract

In a pursuit towards determining the effect of Expanded Elbow Pipes and Mufflers in Fuel Consumption of Four-Cycle Motorcycle Engine, specifically this paper confined that there is no significant difference in the mean fuel consumption between stock elbow pipes and mufflers and expanded elbow pipes and mufflers. Engines’ back pressure, defined as the exhaust gas pressure produced by the engine on its’ exhaust system resulting to resistance of these gasses to be discharge into the atmosphere. Increased back pressure levels can cause increased emissions, fuel consumption, and negatively affect engine performance. Stock elbow pipe and mufflers installed in motorcycles does not possess the technology to limit the effect of back pressure that an Expanded elbow pipes and mufflers can provide, problems in back pressure can be address through the use of expanded elbow pipes and mufflers which can help the engine and better exhaust flow. This methodology shall give improved engine performance and afford lesser fuel consumption in a four-stroke motorcycle engine and the exhaust system setup reduced back pressure.
