The combustion and emission characteristics of the diesel engine operated on a dual producer gas-diesel fuel mode

Producer gas is a low energy density gaseous fuel converted from carbonaceous materials through a thermochemical process. The gas can be exploited to operate a diesel engine on a dual-fuel mode to partially reduce diesel fuel use. The present study intends to investigate the impacts of gas flow rate...

Gitano-Briggs, H. W. Lopez, Neil Stephen A. Biona, Jose Bienvenido M. Producer gas is a low energy density gaseous fuel converted from carbonaceous materials through a thermochemical process. The gas can be exploited to operate a diesel engine on a dual-fuel mode to partially reduce diesel fuel use. The present study intends to investigate the impacts of gas flow rate and diesel injection timing (DIT) on a diesel engine operated on a dual-fuel mode at a high engine speed of 3,000 rpm. The findings highlight that the peak pressure occurred later and was lower at a higher gas flow rate. The peak pressure was higher and advanced when the DIT was advanced and the engine load was increased. Large increases in CO2, HC, and CO concentrations were found in the dual-fuel mode, specifically at low loads. Unlike the findings using a medium engine speed, the specific NOX emissions were higher for the dual-fuel mode operation. Based on these empirical results, a dual-fuel engine should be operated at a high engine load and a gas flow rate of 10 kg/h. A slightly advanced DIT is required – roughly 3 degrees of crank angle. Furthermore, a dual producer gas-diesel engine should not be operated at the maximum gas flow rate. © 2019, Paulus Editora.
