Global warming issues in today's society has been much attention. Therefore, we designed an exhaust pipe can reduce the amounts of carbon dioxide and carbon monoxide and other emissions from the exhaust gas motorcycle. Initially we found that carbon dioxide emissions from motor vehicles in today's society it is a very large. So we started looking for material sufficient to absorb all kinds of exhaust. Use the most simple structure, low cost. Completion of this enough to absorb large amounts of exhaust gas exhaust filter. Such works through testing, found that well absorbed, even more noteworthy is that it can be reused, just the contents can be cleaned, so not only can achieve the effect of reducing carbon emissions. Also can be reused, not wasted.
