Experimental Investigation on Electric Wastegate Turbocharger's Application on Diesel Engine
Experimental investigation of the influence of electric wastegate turbocharger's applicattion on engine performance and emission is carried out on a diesel engine that meets national VI B regulation.Re-sults show that fuel consumption improves at middle and high engine speed condition,what is more,fuel consumption gets better and exhaust temperature becomes higher at low load condition.SCR catalyst aver-age temperature of WHTC cycle increases from 226℃to 246℃,average brake specific NOx emission of cold WHTC cycle reduces by 25%and weighted specific NOx emission reduces by 8.6%for cold and warm WHTC based on optimization of electric wastegate control strategy.
