A solution to use the raw biogas in DI diesel engine obtained from P. pinnata de-oiled cakes.
Improvement in BTE for biogas–diesel dual fuel operation is possible with advanced pilot fuel injection.
Part load performance and emissions of the engine are improved.
Pilot fuel injection advance of 3 °CA, gives about 4.7% increase in BTE.
The NO and smoke emissions are significantly lower in the dual fuel operation than that of diesel operation.
