The dual fuel combustion mode, the use of bi-fueled natural gas and diesel fuel, is an attractive alternative to standard spark ignition or compression ignition combustion modes due to potential benefits of lower CO2 emissions, lower fuel costs and the use of a fuel with an alternative supply chain. Besides the potential benefits, the dual fuel combustion mode also has its challenges. There is limited data available in the literature that illustrates how the performance of a dual fuel engine changes over the entire engine map at various operating conditions; this paper presents a comprehensive set of experimental results obtained with the conventional dual fuel operation (diesel/natural gas) at ambient intake conditions to help fill this knowledge gap.
