In modern engine and vehicle design there are tradeoffs between engine performance and emissions that need to be optimized to get the best performance with least cost. This free seminar will focus on using integrated system simulation for the purpose of analyzing and optimizing the entire vehicle system to achieve target performance and emissions goals. For example an integrated model can be used to study the effects of changing EGR fraction or cooling the EGR on the engine performance and NOx predictions of the diesel engine, and simultaneously the SCR catalyst volume can be optimized to meet the drive cycle NOx tailpipe emissions requirements.
Each section of an integrated demonstration model will be reviewed focusing on the process involved in creating each sub-system model including:
A) Fully Detailed (1D) to Fast Running Model (FRM, 0D flow system, detailed cylinder) engine model conversion
B) Cylinder emissions modeling:
a. Emissions maps
b. Predictive kinetic NOx, CO, and soot models
C) Overview of detailed aftertreatment modeling
D) Vehicle and controller modeling overview
E) Integration techniques – combining engine, vehicle, and aftertreatment sub-systems into one model that is capable of running on the order of real time or faster
F) Demonstration of emissions managements optimization on a Diesel Hybrid Electric Vehicle:
a. Modeling techniques for studying DOC warm-up
b. Impact of Electrically Heated Catalyst on emissions and fuel consumption
c. Optimization of EGR fraction and SCR volume for best engine performance and tailpipe NOx reduction
d. Modeling of clean EGR – EGR taken from downstream of catalyst, or catalyst placed in EGR loop
Due to the limited room capacity, seats will be allocated preferentially to OEMs and suppliers. Computers will be available to use during the training. Attendees are encouraged to bring USB flash drive to save seminar material.
