23 Dec SCR or EGR now that is the Question
The key players in the industry are at odds, in the courts, with the EPA and the media. One is gambling on what they call the “in-cylinder solution” (EGR) whereas all other players are going with the SCR (Selective Catalytic Reduction) solution, which incorporates the use of a DEF (diesel exhaust fluid) to meet the 2010 regulations. Another correlation to the situation is that one group is predicting an increase in fuel economy while the other is gambling on unconfirmed technology.
The only guarantees at this point are: the cost is going to increase and the legal battles will continue, with neither system approved beyond 2011. The end result will undoubtedly be cleaner air to breathe for current and future generations, but there’s an outside chance the industry could lose yet another supplier if their respective technologies don’t function as designed.
This is a hot topic right now. I’d love to know what the thoughts are out in the industry in terms of what the pros and cons are for each of these two technologies. What’s are your thoughts for each — pro and con?
