Because of increased emissions in diesel engines, dual fuel engines are more
attractive over diesel engines. Gaseous fuels can be effectively used in diesel engines
modified to work in dual fuel mode. Diesel blended with methyl ester of jatropha oil in the
ratio of 80:20 (volume basis) is utilized as a pilot fuel, and LPG is inducted along with the
fresh air at a constant flow rate of 175 g/hr through the intake manifold of the CI engine.
LPG – Biodiesel dual fuel engines emit marginally higher NOX emissions at full load, as
compared to that of diesel engines, as higher cylinder temperatures achieved during
