Experimental analysis of exhaust gas after treatment system using water scrubbing in a single cylinder diesel engine for diesel and biofuel blends

摘要

A low-cost exhaust gas after treatment system called water-scrubbing is attempted in this paper. An emission treatment setup is fabricated, which is installed in the exhaust of the engine. This takes the exhaust gas and sprays water in the exhaust and passes it through the chamber containing silica gel. An attempt is made to investigate experimentally the performance and emission characteristics of a direct injection (DI) diesel engine, with and without water injection at the exhaust using diesel fuel (DF), diesel-Karanja oil blend (DKB) and diesel-Jatropha oil blend (DJB). The exhaust gas after treatment system helps to reduce NOx, CO and Particulate matter. The performance of the engine has also been monitored to determine whether the engine has any decrease in performance when the setup is used and it is found that there is no change in the engine performance.
