摘要：

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.　All　right　reserved.
