Experimental investigations on high pressure assisted waste mix cooking oil powered biodiesel fuelled CRDI engine and injection parameter studies

Abstract

The worldwide market estimation of biodiesel is extended to outperform in future. The developing conspicuousness of biofuels as an alternative source instead of customary petroleum products is the critical factor to enhance the market development. Expanding use of biodiesel in power age and automotive fuels is likewise extended to enhance market development over the estimate time frame. For single injection strategies adopted on the performance evaluation of CRDI facility operated engine fueled with waste mix cooking oil (WMCO) B20 blend comparing with the neat Diesel Extraction of Biodiesel from WMCO collected from local area through transesterification test rig is satisfactory. Properties of B20 WMCO biodiesel were determined using ASTM standards were comparable to Diesel fuel. Single injection assisted CRDI engine fuel injection at optimized conditions showed improved overall engine performance at 80% and 100% engine loading operation respectively. For Diesel and B20 WMCO biodiesel, IT of 10 O bTDC, IP of 900 bar, and with more number of holes showed excellent performance and were selected as optimized parameters. Retarding the IT from 15° to 10°bTDC increases BTE and reduced emission except for NOx and lower ID, CD and PP, HRR are increased respectively. With keeping IT of 10°bTDC and increasing IP from 600 bar to 900 bar led to further improvement in overall engine performance. Finally increasing the injector holes from 5 to 8 result in the enhanced engine performance with both Diesel and Biodiesel respectively.
