The use of models is widespread in automotive industry in the preliminary feasibility assessment of novel powertrains, determination of system configuration and subsystem requirements, and operating strategy. Although optimal control problems arise naturally within this context when faced with analysis of transient performance requirements, they are rarely treated other than by simulations. The...

Turbocharger is one of the vital parts a diesel engine causing high failure rate. Its surface vibration signal contains important time-varying features. To better process nonstationary signals with features and perform time-frequency transformation on turbocharger signal, novel multi-objective matched synchrosqueezing chirplet transform method proposed in this paper. The based Linear Chirplet T...

Abstract This paper describes a possible approach of designing an unconventional turbocharger using co-simulation method. Our goal is to design turbochargers running optimally during pulsating and transient modes. It means develop tool capable between 3-D 1-D CFD. must be fast precise enough provide reliable result. Influence coarse mesh versus fine was examined. Different time step size applie...
