2009 BMW 335d – With an SSCR replacing its liquid based SCR system, extended maintenance intervals and lower costs could result.
Auburn, Hills, MI. -- FEV will show a Solid Selective Catalyst Reduction (SSCR) System installed in a Dodge Ram turbo-diesel P/U truck at the upcoming 2009 SAE World Congress in Detroit. The Solid SCR system has been installed on a Dodge Ram 2500 as a technology demonstrator during the development process. The announcement was made by
"All of our customers need to comply with future emissions regulations without sacrificing fuel economy," said Dr. Dean Tomazic, VP of FEV, Inc.'s Engine Performance and Emissions Division. "We have invested significant resources in the development of aftertreatment technologies, the Solid SCR being just one example. This technology offers high potential due to its packaging advantages and the fact that it does not present the same low temperature issues that exist with liquid urea systems."
The Solid SCR System is a viable alternative to a liquid urea injection system. With a volume reduction of approximately 70 percent, the SSCR system offers equivalent or better performance than liquid urea systems. SSCR is scalable to accommodate both light and heavy-duty applications including both off-highway and stationary applications. The SSCR system requires less energy for sublimation of the ammonia carbamate solid, which occurs at 60 degrees C. Sublimation is also reversible as the cooling gas reforms back to ammonia carbamate.
The potential use of a solid urea cartridge-based SCR system would dramatically reduce or eliminate the issues associated with development of a large-scale infrastructure for a liquid urea refilling. Degradation concerns are also reduced due to use of a stable solid ammonia carbamate. The solid cartridge will last three (3) times longer than a similarly sized liquid urea system and the SSCR system eliminates the need for costly heated tanks and supply lines.
Could this cartridge based system be the silver bullet the diesel industry requires to make it consumer and manufacturer acceptable?
