| Abstract:A new type of dual fuel engine control system was installed in a six cylinder multi-point injection marine dual fuel engine to conduct application research. The propulsion characteristics test under both pure diesel and dual fuel mode was carried out to test the performance of the control system. The application results showed that with the new control system, the marine dual fuel engine achieved stable operation, the performance indexes met with the design requirements. Under the rated condition, the LNG replacement rate could reach more than 70%; the soot emission is 1.90 FSN under diesel mode, and is 0.13 FSN under dual fuel mode. The effect of energy saving and emission reduction is obvious. |
