Abstract:
This paper summarizes a review of dual-fuel natural gas/diesel engine technology carried out for the Gas Research Institute. In the past, dual-fuel natural gas/diesel engines have been relegated to a few small niche markets, but our review has shown that dual-fuel engine technology has significant potential. Potential advantages of dual-fuel engines include diesel-like efficiency and brake mean effective pressure (BMEP) with much lower emissions of oxides of nitrogen (NOx) and particulate matter. New technologies offer solutions to the problems of poor efficiency and emissions at light load. Dual-fuel engines can be designed to operate interchangeably on natural gas with a diesel pilot, or on 100% diesel fuel. Many existing diesels can be converted to dual-fuel operation. Preliminary economic analyses show that such conversions could be justified from the fuel cost savings alone in applications such as railroad locomotives, marine vessels, mine trucks, and diesel power generation systems.
