The Performance of Green Muffler With Eggshell Tailpipe Exhaust Filter

Abstract

INTRODUCTION

This research paper is about a Green Muffler (GM), which is a muffler designed to reduce carbon emissions of a vehicle, specifically made for motorcycles and tricycles. The GM was designed to have the capability of adsorbing carbon emissions. Inside the GM were two containers meant to contain cracked eggshells which act as the adsorbent of Carbon emissions emitted by the engine. GM is 30.48 cm long (12") and 10.16 cm wide (4"). The containers measure 8.89 cm long (3.5"). The silencer is in the middle which is 7.62 cm long (3"). The GM is not an entire tail pipe, it's only a muffler, which is attachable to a tailpipe modified to have a replaceable muffler.

METHODS

The performance of the green muffler was established by: (1) computing the percentage decrement of the emitted specific carbon emission using the existing muffler as the basis; and (2) comparing specific carbon emission using the GM with the Euo IV Standard.

RESULTS

A 71 percent decrease in carbon monoxide (CO) and 77 percent decrease in hydrocarbon (HC) were achieved. in comparison to the Euro IV standard given by the emission center, the total emission with the Green Muffler was brought down to 11.6 percent CO in volume and 1.2 percent HC in ppm.

DISCUSSIONS

These data have proven that the use of Green Muffler effectively decreased the carbon emission of motorcycles. The ground eggshell utilized as adsorbent in the designed exhaust tailpipe filter was effective. The green muffler therefore could be recommended for commercial use.
