Effect of different geometrical changes in the intake manifold of a DI diesel engine fuelled with biodiesel-diesel blends 2020-01-0346
The aim of this research work is to investigate on a single cylinder, 4-stroke DI diesel engine fuelled with waste cooking oil methyl ester (WCOME)-diesel blends by changing the intake manifold. Considering this, a research was carried out by fitting two different intake manifold. One is normal intake manifold, and other is internal buttress threaded intake manifold (IBTM), which is designated in this article as IBTM. In this experimental investigation, a suitable blends such as WCOME10 (10% of WCOME + 90% diesel) and WCOME20 (20% of WCOME + 80% diesel) were tested in a different intake manifolds as mentioned above. Based on the results obtained in this study, IBTM exhibits a better performance and emission results when compared to normal intake manifold. The carbon monoxide (CO), hydrocarbon (HC) and smoke emissions were decreased by about 26.5%, 36.76% and 24.09% respectively, whereas, NOx emissions were increased by about 23.03% for IBTM on compared to normal intake manifold when fuelled with diesel.
