Performance and emission of CI engine fuelled with camelina sativa oil

The paper describes the results of the tests of CI Perkins 1104C-44 engine fuelled with camelina sativa oil. The engine was not especially calibrated for fuelling with the vegetable fuel. During the test the engine performance and emissions were analysed. For comparison the same speed characteristic was examined for standard fuelling of the engine with diesel oil. In order to understand the engine performance and emission the mass fraction burnt and the rate of heat release was calculated and compared for the same energy provided to the engine cylinder with the injected fuels. The results show that there is possible to receive relatively good engine performance for fuelling the engine with camelina sativa oil but there is a need to change the calibration parameters of the engine fuel system when the engine is fuelled with this fuel.

► Camelina sativa as a potential source of alternative fuel.
► Neat camelina sativa oil as a fuel for CI engine.
► The engine performance and emissions of CI engine fuelled with neat camelina sativa oil.
► Comparison of rate of heat release for camelina sativa oil and diesel oil.
