Designing more efficient and robust emission control components and exhaust systems results in more efficient performance, reduced backpressure and fuel penalty, and higher conversion efficiency. This course will help you to understand the motion of exhaust flow in both gasoline and diesel emission control components including flow-through and wall-flow devices such as catalytic converters, NOx adsorbers, diesel oxidation catalysts, diesel particulate filters as well as flow through the overall exhaust system.

Meeting the requirements of heavy-duty engine emissions regulations is a challenge for all engine manufacturers. Since the introduction of Exhaust Gas Recirculation (EGR) in medium and heavy-duty diesel engines, these systems have become more sophisticated and tightly integrated with emission control systems. This 2-day seminar will explore the advantages and disadvantages of EGR and the most effective implementation of various EGR systems. This seminar will begin by defining EGR and why it is used in diesel engines, along with an explanation of the mechanisms by which EGR is able to reduce NOx.

Public awareness regarding pollutants and their adverse health effects has created an urgent need for engineers to better understand the combustion process as well as the pollutants formed as by-products of that process. To effectively contribute to emission control strategies and design and develop emission control systems and components, a good understanding of the physical and mathematical principles of the combustion process is necessary. This seminar will bring issues related to combustion and emissions "down to earth," relying less on mathematical terms and more on physical explanations and analogies.

Lean burn engines (diesel and GDI) boast higher fuel economy and cleaner emissions than conventionally tuned engines while producing equivalent power. They employ higher combustion chamber compression ratios, significant air intake swirl and precise lean-metered direct fuel injection. The downfall of lean-burn technology, however, is increased exhaust NOx emissions (due to higher heat and cylinder pressure) and a somewhat narrower RPM power-band (due to slower burn rates of lean mixtures). Removal of NOx from exhausts is a critical need for emission standards and ambient ozone requirements.

Papers for this session are on the general topics of combustion engine gaseous emissions (regulated and non-regulated). This includes papers discussing well-to-wheels CO2 production for alternative technologies, fuel economy and all greenhouse gas emission research with their primary focus on engine, emissions, fuels, control or related components or sub-components within. It also includes hydrocarbon species and specific NOx species production over aftertreatment devices.

Presentations are invited on technology developments and integration of these technologies into new emission control systems. Topics include the integration of various diesel particulate matter (PM) and diesel Nitrogen Oxide (NOx) reduction technologies plus analogous technologies for the growing population of direct injection gasoline engines. Novel developments in sensors and control systems will also be considered.

Abstract Natural gas (NG), which consists of mostly methane, can be co-combusted with diesel fuel in existing compression ignition engines through dual fuel technology with reasonable engine modifications. The removal of short-chain alkanes (e.g. CH4, C2H6 and C3H8) of a dual fuel (natural gas and diesel) engine raises a distinctive topic to the exhaust aftertreatment system (ATS). However, there are few studies reported based on tests with real engine exhaust. This present study focuses on the conversion of short-chain alkanes by Co, Ni and Cu/ZSM-5 catalysts, which are commonly used for oxidation/partial oxidation and reforming. These catalysts are tested with exhaust of a dual-fuel (natural gas and diesel) engine. The complicated and dynamic exhaust composition, determined by the engine loading and natural gas substitution, can result in different components in the exhaust and various conversions for species.

Abstract Automotive SCR systems for diesel NOx reduction are dimensioned to reduce NOx efficiently in all driving conditions. In this regard the DEF storage and delivery system is developed to operate in a full range of temperatures, voltages, pressures, etc. To allow a control for optimal performance, sensors are added in the system (temperature, level, pressure sensor). Recently, a DEF quality sensor has been added to assure the correct concentration of urea in water in the onboard DEF tank. Now the question is raised how to assure that the DEF quality sensor is operating correctly and is giving an accurate indication of the liquid in the tank. The objective of this study is to define an independent method (PQD) to verify liquid quality, and challenge the signal generated by the DEF quality sensor. This study describes a possible method and the progress on its validation in various automotive driving conditions.

Abstract Recently, the European Union has adopted a new regulation on Real-Driving-Emissions (RDE) and also China is considering RDE implementation into new China 6 legislation. The new RDE regulation is focused on measuring nitrogen oxides (NOx) and particulate number (PN) emissions of both light-duty gasoline and diesel vehicles under real world conditions. A supplemental RDE test procedure was developed for European type approval, which includes on-road testing with cars equipped with portable emission measurement systems (PEMS). This new regulation will significantly affect the engine calibrations and the exhaust gas aftertreatment. In this study the impact of the new RDE regulation on two recent EU 6b certified turbocharged direct injected gasoline vehicles has been investigated. A comparison of several chassis dyno drive cycles with two new defined on-road RDE cycles was performed.

Abstract Diesel oxidation catalysts with ultra-low NO2 emissions have been developed based on palladium-tungsten (Pd-W). The catalysts are supported by aluminum-yttrium oxides (Al2O3-Y2O3) nano-washcoat on sintered metal fibers. Elemental composition analysis was performed using Energy Dispersive Spectroscopy (EDS) to quantify the distribution of the Al2O3-Y2O3 nano-washcoats and Pd-W catalysts on the surface of the metal fibers. Initially, emissions measurements were conducted to evaluate the performance of Pd-W catalysts using small coated samples of sintered metal fibers. The results show that the catalysts selectively oxidize CO into CO2 and reduce NO2 into NO, resulting in over 90% reduction in CO emissions and up to 85% reduction in NO2 emissions. Scale-up of an Active Diesel Particulate Filter (ADPF) was then tested on a Cummins 5.9L ISB diesel engine using the US-FTP transient test cycle and the ISO 8178 8-mode test cycle.
