NOXEMISSION CONTROL AND ANALYSISOF C.I ENGINE EXHAUSTUSING WATER SPRAY AND SILICA GEL TREATMENT

Abstract

The Internal Combustion engines play major role in all modes of transportation and electricity generation. The main drawbacks of these I.C Enginesare their hazardous emissions causing environmental pollution. The diesel engine emissions are considerably high compared to the petrol engines. The main pollutants contributed by diesel engines are Carbon monoxide (CO), Oxides of Nitrogen (NOx), UnburnedHydrocarbons (HC) and other particulate emissions. Among these emissions, NOxis considered more dangerous so it should be reduced. Hence the emission control became the biggest challenge for automobile companies. So, the only way to reduce emission is byfinding various methods used to control it. The main objective of this paper is to address the reduction in NOxemission by spraying pressurized water droplets in the exhaust gas flowand making the treated gas to pass through the Silica Gel layer for further NOxreduction. This method is considered as simple and cost effective method compared to other emission control methods. The method showed considerable reduction in the exhaust emission of the C.I Engine.
