Experimental Investigation on Jatropha-Methanol Blends in Direct Injection Diesel Engines

Abstract

This paper describes about the usage of Jatropha fuel in direct injection water-cooled diesel engine. In order to make use of Jatropha fuel in diesel engine, the properties of Jatropha oil has to be converted to diesel fuel, so for that methanol was added. There are three different blends are prepared by varying the ratio of Jatropha and methanol mixture, such as blend 1 (Jatropha 75%, methanol 25%), blend 2 (Jatropha 80%, methanol 20%), blend 3 (Jatropha 85%, methanol 15%). The prepared fuels are supplied to the conventional diesel engine, then the performance and emission characteristics were analysed. It is found that Jatropha methanol mixtures results are acceptable in half load and highly considerable in full load operation. Considerably torque developed is very low in low load than half and full load operations. Methanol addition has improved the performance and emission characteristics.

Optimizing soybean biofuel blends for sustainable urban medium-duty commercial vehicles in India: an AI-driven approach

“…The significant downfall in emission of D80S20 blend might be credited to elevated oxygen level and high moisture level of biodiesel. An elevated moisture percentage in biodiesel leads reduction in chamber temperature which in turn limits the formation (Sarıdemir and Agbulut 2022 ; Agbulut et al 2020 ; Prakash and Dhanasekaran 2019 ) (Fig. 13 ).…”
