| Abstract:In accordance with the SCR system matching and calibration experiment for a marine medium speed diesel engine, reasonable and effective performance optimization and adjustment scheme was designed, the optimization technical measures for reducing the comprehensive operation cost were introduced and the matching test had been done. The results of the test indicated that the diesel engine met the Tier Ⅲ Standards instead of Tier Ⅱ Standards. Under the premise of ensuring the power output of the diesel engine remain the same, fuel economy had been improved, and the fuel consumption was decreased by 3% to 5%. Taking into account the consumption of urea, the comprehensive operation cost was decreased by 2% to 3%. The results indicated that SCR could reduce the NOx emission effectively and the cost was relatively low, the application prospect of SCR is quite broad in the field of marine diesel engine. |
