EFFECT OF FLOW RATE AND CONCENTRATION OF CARBAMIDE ON THE REDUCING NOx EMISSIONS IN PALM BIODIESEL FUELED RESEARCH ENGINE

Author(s): SIVA, R* and YUVARAJAN DEVARAJAN**

This study examines the consequences of concentration and flow rate of carbamide (urea) to reduce NOx emissions from a diesel engine propelled with biodiesel. Taguchi-Grey relational-based multi-response optimisation method was employed for test-plan. Results revealed that carbamide flow rate and its concentration have a positive impact on NOx emissions reduction in unmodified diesel engine. The obtained results are also justified with results attained from ANOVA. It is also confirmed that the results obtained in the experimentations are in line with the calculated values obtained Taguchi technique. Hence, the usage of carbamide in tailpipe is an effective way in reducing NOx emissions from diesel engine.
