The head of GM diesel engineering talks about the 4.5, and you get a look at the cylinder head design. Talk about ingenious.

great articles. i am still nervious about this whole system. particulate filters, urea that they are hoping will last longer than the oil change time, and a very unique design. i am just worried that all of this leads to high maintenance costs and reduced fuel efficiency, as well as some problems in the first few years.

Looks like it will be a pita to work on and expensive. With all the emissions bs, it will be plugged with soot in no time imo. The design is awesome. Less parts and more compact with good power. Can't wait to see how it all works together.
