Simultaneous reduction of NO{sub x} and smoke in a dual fuel DI diesel engine

Abstract

Highlights: • A solution to use the de-oiled cakes disposed from oil industries. • Biogas produced from Karanja de-oiled cakes contains about 73% methane. • Simultaneous reduction of NO and smoke is possible with KME–biogas dual fuel operation. • Up to 30% replacement of KME is possible with induction of biogas at 0.9 kg/h. • Improved part load performance and emission with KME–biogas dual fuel. - Abstract: This paper presents the results of an experimental investigation conducted on a compression ignition (CI) engine, modified to run on dual fuel mode, using biogas as a primary fuel and KME (Karanja methyl ester) as a pilot fuel. The biogas was produced by anaerobic digestion of Pongamia pinnata (Karanja) seed cakes. In dual fuel mode, the biogas was inducted at four different flow rates, viz. 0.3 kg/h, 0.6 kg/h, 0.9 kg/h and 1.2 kg/h through the intake manifold of the engine. The biogas flow rate of 0.9 kg/h gave a better performance and lower emissions, than those of the other flow rates. The NO and smoke emissions were found to be lower by about 34% and 14%, than those of KME operation, at full load. The ignition delay was longer by about 1–2  More>>

The part load performance was found to be better in dual fuel operation, with reduced emissions of NO and smoke, in comparison with KME. The ignition delay at part load in dual fuel operation was also lower than that of KME operation.}
