Peter, did CAT claim they are already set for Euro 5 without using egr or scr? Would that be ACERT? I tried to look round the CAT site for more details, but all I could find was some general stuff mainly aimed at sales. It seems to me they are doing a lot around cooling the inlet, and theres a tricky looking turbo!
Mal,
ACERT is Cat’s answer to emissions technology. It is similar to EGR and also uses turbo compounding. To achieve Euro4 and 5 they need a particulate filter and catalyst, similar to the one MAN propose to use.
The new ACERT engine range is a litre bigger than its Euro 3 equivalent i.e. the C12 becomes a C13 and will be max rated at over 500hp. Cat claims a 10% fuel saving over the C12.
