This one-day free seminar will focus on improved modeling of turbocharged engines by integrating sophisticated models of the charge air cooler (CAC) and EGR cooler. The resultant model takes advantage of the multi-circuit capability of GT-SUITE so that there is only a modest increase in computational speed when detailed CAC and EGR cooler detail are added to an engine model, thus making this methodology practical for a wide variety of simulation studies. This class is primarily intended for engine performance engineers, and as such, no previous experience with heat exchanger or underhood modeling is required. The training facility will provide a computer for each attendee.

The fully integrated model is applicable to both steady state and transient simulations and enables modeling of complex interactions such as engine derating due to turbocharger over speed and surge. The more accurate prediction of engine inlet temperature is also relevant to combustion topics such as ignition delay for predictive diesel combustion and knock in SI engines. The integrated model can be used to address a variety of questions such as:

1)      What is the real torque curve at 1000 meters altitude on a 35C day?

2)      How much would a bigger or better CAC improve engine performance?

3)      Is engine performance change from vehicle speed and head/tail wind?

4)      Is the optimal cooling fan control strategy for the cooling system also optimal for the intercooler?

5)      Is the CAC performance degraded when the nearby AC condenser is rejecting heat? Can negative interactions be reduced by changing their relative positions?

6)      How does the EGR cooler size, and coolant flow rate and temperature through the EGR cooler, effect, the engine?

The training will begin with a typical GT-POWER engine model at laboratory conditions (i.e. imposed intercooler and EGR cooler outlet temperatures) and a typical underhood model (as would be used by a VTM cooling system group). The underhood heat exchanger pack will be modeled in both simple 1D and sophisticated 3D underhood models (created in COOL3D). The methodology will be equally applicable to both detailed engine models and fast running mean-value engine models.
 
WHO SHOULD ATTEND?
·         Engine performance engineers who study turbocharged engines, both SI and diesel, at non-laboratory conditions.
·         Cooling (VTM) system engineers who wish to work more interactively with their engine performance colleagues
This training class will not teach how to build basic engine and underhood HX pack models. (Separate training classes are regularly available for model building.) Please do not hesitate to contact the instructor if would like to discuss if this class is a good match for you.
Because registration is expected to be high, first priority will be given to commercial customers, and the number of attendees per company may need to be limited. However, we encourage all who are interested to register, even if on the waiting list; we will try to find a way to accommodate all registration requests.
