Abstract: A dual fuel engine is a compression ignition (CI) engine where the primary gaseous fuel source is pre-mixed with air as it enters the combustion chamber. This homogenous mixture is ignited by a small quantity of diesel; the ‘pilot’; that is injected towards the end of the compression stroke. In the present study, a direct injection CI engine, was fuelled with three different gaseous fuels; methane, propane and butane. The engine performance at various gaseous concentrations were recorded at 1500rpm and ¼, ½, and ¾ load relative to full load of 18.7kW. In order to investigate the combustion performance, a three zone heat release rate analysis was applied to the data. The resulting mass burned rate data are used to aid understanding of the performance characteristics of the engine in dual fuel mode. Data are presented for the brake specific energy consumption of the engine and combustion phasing. The highest primary fuel substitution levels were achieved when using methane under all test conditions and butane proved to be the most unsatisfactory of the three primary fuels. The most promising fuel was found to be propane.
