| Abstract: | Real-time measurement of exhaust gas recirculation(EGR)flow with good stability,high accu-racy and precision of EGR rate was made using the Coriolis flow meter on a turbocharged and intercooled heavy-duty high pressure common rail diesel engine.Engine performance at constant speed and increasing toque(CSIT)process were conducted under 1 650 r/min speed of steady test cycle condition.Test results show that applying the optimized EGR rate and injection parameters under ESC conditions to the transient process ... |
