摘要
对一船用中速柴油机进行了NO_x排放试验,得出并分析了其用作船舶主机时,在持续运行区域内随运行工况变化的NO_x排放特性.柴油机NO_x排放水平与其运行工况密切相关.对于按推进特性运行的船舶主机,排放法规有必要针对NO_x排放实船测试特点,规定合适的标准测试工况,并在台架试验的基础上对因测试工况偏差而引起的NO_x排放误差进行修正.
Based on the NOx-emission test of a medium-speed marine diesel engine, the characteristics of NOx-emission from the engine used as main engine on a ship relating to operating condition in the steady operating area are educed and analyzed. The level of NOx-emission is closely related to the operating condition of engine. For the main engine operated on propeller law, the emission resolution should define the specific and standard operating condition and the NOx-emission error resulting from the difference between practical test operating condition and standard test operating condition should be amended based on the characteristic of NOx-emission educed from the data of bed test.
