Abstract

Jack fruit peel oil (JFPO) exhibits passive chemical characteristics; thereby, dual-fuel mode frequently involves hydrogen to address its combustion difficulties. This strategy has been gaining prominence nowadays. The present investigation investigates on the performance, emission, and combustion characteristics of a direct injected compression ignition dual-fuel engine operating on a binary fuel blend of jack fruit peel oil (JFPO) and diethyl ether with hydrogen induction. The engine was operated by inducing hydrogen gas into the intake manifold of the engine at 8 and 10 LPM with the applied load ranging from 25 to 100%. The test fuel was prepared by blending jack fruit peel oil and diethyl ether in the volumetric ratio of 90:10. JFP brake thermal efficiency was 16% lower than diesel at full load but enhanced by 9% with direct hydrogen induction at a knock limit of 10 LPM and 23% with JFP + H2 + 10% DEE at maximum load. At maximum load, JFP + 10 LPM of hydrogen gas + 10% DEE produces 916 ppm of NOx, which is 44.46% less than diesel. Furthermore, adding hydrogen gas and DEE to air fuel mixture decreased emissions of carbon monoxide and unburned hydrocarbon by 0.702% and 28.30% opa, respectively.
