Catalytic NOx Control Technologies for Diesel & GDI Engines Web Seminar RePlay

I.D.# PD331237ON
Access Period: 30 days
Duration: 6 Hours

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.

This three session web seminar will examine the various catalytic processes for lean burn applications, including Selective Catalytic NOx Reduction (SCR), NOx Trap Technologies (i.e. LNT, NSR), and the combination of SCR, NOx Trap and Hydrocarbon NOx Reduction (LNC). It will focus in on SCR NOx fundamentals, equipping participants with the basic concepts for NOx control and important design parameters for SCR NOx catalyst. The course will examine the system design for SCR in diesel applications including passenger cars and heavy duty trucks, including SCR catalysts, SCR integration with diesel particulate filter, key sensor development catalyst durability issues and urea control.

Is this Web Seminar RePlay for You?
This web seminar will be especially valuable for mechanical, metallurgical and chemical engineers, materials scientists, and chemists involved in the design, operation and calibration of a NOx emission control system for both mobile and stationary source applications, such as automobiles, trucks, buses, ships, locomotives, stationary engines, small engines, etc. It will also help the newly hired engineer assigned to an emission control team, the seasoned veteran who just transferred to the emission control group, sales people responsible for emission controls, plant managers concerned about meeting new regulations with catalytic controls, and regulators now involved in transmission technologies.

Participants should have a basic familiarity with automotive emissions for gasoline engines, diesel engines or off-road applications. The Fundamentals of Catalytic Converter Integration for Emission Control Web Seminar RePlay, is a recommended prerequisite for those with less than three years of experience with catalytic converters.
