A role of the combined effect of fuel injection parameters on a dual fuel diesel engine

Abstract Food waste is continuously disposed from different sources that include hotels, restaurants, canteens, hostel mess, houses etc., Food waste either in mixed form or in segregated form can be utilised for producing energy. In this study, spent tea waste (STW) collected from refreshment stalls, canteens, hostels of an institute campus, and used as a feed stock for producing biogas, a methane contained fuel. Biogas was produced by the co-digestion of STW with cow manure (CM), and utilised as a primary fuel to operate a diesel engine. In the present experimentation, 4-stroke, single cylinder, air cooled, DI diesel engine running at a constant speed of 1500 rpm was used to operate on a biogas dual fuel mode (DFM) to examine the engine behaviour in terms of its combustion and performance characteristics. This study was executed for a set of combinations comprising of 0.5, 0.75, 1.0 kg/h (biogas), fuel injection timing was advanced to a maximum of 3°CA at a regular interval of 1.5°CA from the original 23°CAbTDC and fuel injection pressures of 200, 220 and 240 bar. The results obtained were compared with the baseline diesel, and presented in this research study.
