Catalytic NOx Control
Technologies for Lean Burn
Engines Webinar

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 Webinar (or Webinar Recording) is a recommended
prerequisite for those with less than three years of experience with
catalytic converters.

6 Hours
I.D.# WB1237

Lean burn engines 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 webinar 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.

This webinar 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
