英文摘要	针对柴油机尿素催化还原后处理(selective catalytic reduction, SCR)技术的控制策略验证,基于快速控制原型系统建立了V型模式开发平台.此平台将MATLAB/Simulink搭建的控制模型与发动机台架试验的尿素控制系统无缝连接起来,实现了在发动机台架上实时修改控制策略的目的.基于此控制开发平台提出了台架标定方法,即采用加权分配NO_x排放限值并加以适当调整的台架标定方法.经过试验验证,采用上述方法标定的柴油机,柴油机NNO_x在欧洲稳态测试循环(European steady state cycle, ESC)下的比排放为3.3g/(kW ? h),满足国-IV柴油机排放限值的要求.; For the validation of the control strategy for urea selective catalytic reduction (SCR) system, a V type development platform based on the rapid prototyping system was built. The platform could seamlessly combine the model built by MATLAB/Simulink with the urea control system of an engine test bench to enable the modification of a control strategy on an engine test bench. A bench calibration was developed based on this platform. The method adopts weighted distribution of NOx emission limits in combination of appropriate adjustment. With it a diesel engine with SCR after-treatment is calibrated and the experimental results show that the NOx emission of the engine under the ESC cycle is 3.3 g/(kW??h), which meets the China IV emissions standard. ?, 2015, Chinese Society for Internal Combustion Engines.
