An experimental study on gas-to-liquids and biogas dual fuel operation of a diesel engine

摘要

In the present configuration, GTL replaces diesel, and biogas is used as gaseous fuel in the dual fuel (DF) operations. The effects of this substitution have been evaluated from the perspectives of second-law of thermodynamics. The results are compared with the diesel single-fuel, GTL single-fuel and GTL-biogas DF operations. Also, engine out emissions have been compared to understand the environmental impact of these fuel combinations. The results show that DF operation offers up to 80 pilot liquid fuel replacement by biogas, however, some reductions in energy and exergy efficiencies are observed.
