My client wants to replace an existing radiator cooled 100KW E/G with an air-cooled unit. The purchase and installation was to take place in 2007. As it turns out, no air-cooled engine manufacturer will be able to deliver such an engine in 2007 because the manufacturers have not met EPA's Tier 3 requirements that become effective Jan 2007.

For me, this has caused some problems. But for you, I thought you might find it interesting. I'd think the EPA and manufacturers would be able to work things out in a timely fashion so this interruption would not have occurred.
