REDUCTION OF CO & HC EMISSION OF GASOLINE ENGINE WITH CHARCOAL - OIL SILENCER

The automobiles play an important role in the transport system. With an increase in population and living standard, the transport vehicles as well as car population is increasing day by day. In addition to thi s there is steep increase in the number of two wheelers during the last two decades. All these are increasing exhaust pollution and particularly in metros as density of these vehicles in metros are very high. Lot of efforts are made to reduce the air pollu tion from petrol and diesel engines and regulations for emission limits are also imposed in USA and in a few cities of India. Undesirable emissions in internal combustion engines are of major concern because of their negative impact on air quality, human h ealth, and global warming. Undesirable emissions include unburned hydrocarbons (HC), carbon monoxide (CO), nitrogen oxides (NOx), and particulate matter (PM). There are many methods to reduced these emissions from SI engine, but in this work attempt has be en made to study the effect on emission treating exhaust outside cylinder using the Charcoal - Oil incorporating in silencer
