2020 Chevy Duramax 3.0 Diesel
The Chevy 3.0 Duramax has been delayed due to the EPA which is a shame, but not surprising. Also not a fan of the timing chain installed on the rear of the engine. Link

Really good look at the technical aspects of the engine.
The oil pump drive belt is bathed in oil and requires the transmission (and transfer case if 4x4) be removed to service it 150k minimum life expectancy for the belt.
I also found it interesting that they went with a post combustion diesel injection event from the normal in cylinder injectors to regen the DPF, rather than a dedicated injector like they had on the V8 Duramax which I always thought was a smarter solution to the DPF regen process. I guess they figured out a way to stop that fuel from diluting the engine oil which used to be an issue for DPF equipped trucks.
I realize it's good for packaging, but I question the decision to have a very hot DPF right next to the engine under the hood.

Heavy Equipment is packaged the same way and there are no issues with heat and they don't go 70 mph.
