EGR coolers are used in combustion engines to reduce NOx emissions. However, heat transfer in these coolers also results in thermophoresis-temperature-gradient driven motion of suspended particles towards cooler regions-which leads to significant soot deposition. Presenter Meisam Mehravaran

Some the OBD-II regulations have been around for a long time or seem to be intuitively obvious. It is easy to assume to assume that everyone knows how to implement them correctly, that is, until someone actually reads the words and tries to do it. Most often, these issues come up when modifying existing OBD features, not when creating completely new ones. This presentation contains a few examples of features that should have been easy to implement, but turned out not to be easy or simple. Presenter Paul Algis Baltusis, Ford Motor Co.

From 2009 until present Toyota has had a demonstration program of Prius PHV which is comprised of 600 vehicles throughout Japan, Europe and in the US. The vehicles were given to government agencies, corporations, utility companies and private individuals to use. With these demo units Toyota wanted to understand the market reaction and real world impact of plug-in technology on gasoline displacement with increased use of electricity as a fuel. This presentation shows that approximately 50% of fuel was saved using the PHVs in the US. An experiment in Toyota City shows that if public infrastructure is optimized to be convenient and located where people normally park, there is a potential to achieve an ideal fuel savings of 61%. The demonstration program shows that plug-in technology in fact saves fuel and that the proper infrastructure can optimize the fuel savings of plug-in hybrids. Presenter Avernethy Francisco, Toyota

Diesel Dual Fuel, DDF, is a concept which promises the possibility to utilize CNG/biogas in a compression ignition engine maintaining a high compression ratio, made possible by the high knock resistance of methane, and the resulting benefits in thermal efficiency associated with Diesel combustion.

Powertrain Systems development is facing unprecedented challenges driven by the convergence of many factors: increasing government regulations for tailpipe emissions, diagnostics and fuel economy, increased competition, shorter development cycles, and tighter program budgets. Using telematics and information technology to automate the evaluation of a system�s robustness enables engineers to focus their time on problem areas during their normal development process and launch with quality. This presentation will use real world examples to detail how this methodology was jointly applied by Control-Tec and Ford Motor Company to identify and improve the system performance of Ford�s Air-Fuel Imbalance Monitor before production. Presenter Bill Leisenring, Control-Tec LLC

A combination of laboratory reactor measurements and vehicle FTP testing has been combined to demonstrate a method for diagnosing the formation of NO2 from a diesel oxidation catalyst (DOC). Using small cores from a production DOC and simulated diesel exhaust, the laboratory reactor experiments are used to support a model for DOC chemical reaction kinetics. The model we propose shows that the ability to produce NO2 is chemically linked to the ability of the catalyst to oxidize hydrocarbon (HC). For thermally damaged DOCs, loss of the HC oxidation function is simultaneous with loss of the NO2 production function. Since HC oxidation is the source of heat generated in the DOC under regeneration conditions, we conclude that a diagnostic of the DOC exotherm is able to detect the failure of the DOC to produce NO2. Vehicle emissions data from a 6.6 L Duramax HD pick-up with DOC of various levels of thermal degradation is provided to support the diagnostic concept.

The OBD approval process can be a frustrating time for both manufacturer and ARB staff. For manufacturers, a long approval process can sometimes mean accepting deficiencies prematurely in exchange for an approval. For ARB staff, they are inundated with highly technical information which they must review, garner understanding of and then apply their experience to evaluate it for compliance. OBD approval anxiety can be minimized, if not avoided, when manufacturers understand ARB�s expectations. This presentation will take you through some unwritten rules and common pitfalls which can impede the approval process, thus providing a guideline to a less painful and more efficient certification document review and approval.
