dc.description.abstractThe diesel engines mainly generate a tremendous quantity of carcinogenic oxides of nitrogen (NOx) and soot. The recently reported works reveal that the conversion of pure diesel mode (PDM) to dual fuel mode (DFM) of engine operation has a great ability to curtail the NOx and soot. Moreover, in DFM both renewable liquid and gaseous fuels can simultaneously be used. In this context, during the last two decades, biodiesels, alcohols, and ethers in various forms as pilot and biogas as the attractive inducted gaseous renewable fuels are found. However, owing to the different ignition qualities and heating values of the fuels being chosen, there is a performance penalty in DFM as compared to PDM. Thus, the researchers have observed comparatively more deterioration in DFM engine performance at engine standard compression ratio (CR) and injection timing (IT). Nevertheless, the major benefits to run the DFM engine at standard CR and IT are easy to fall back to PDM in case of shortage of gaseous fuel. Hence, keeping this vista in mind, the present study aims to improve the biogas run DFM engine performance (at standard IT =23 CAD bTDC and CR = 17.5) that is competitive to PDM using various liquid oxygenated fuels blended with diesel fuel. This idea is mainly to generate the power in the rural areas of the developing countries like India.en_US
