WTF??? | Ford EcoBoost Engines Now Have EGR Coolers

Well this is a new one. We recently had a 2019 Ford Ranger FX4 in for testing. For those unfamiliar with the specs of Ford's reborn small'ish truck, it is currently only available with a 2.3L EcoBoost 4-Cylinder engine and the 10R80 10-Speed Auto. That mill has proven to be pretty stout in tuned Mustang application dating back to 2015, and there are a few guys turning them up in Rangers too.

However, as I was poking around under the hood of our test truck I noticed something odd. Ford is equipping the Ranger's 2.3L with an Exhaust Gas Recirculation ("EGR") system that also includes a tiny EGR Cooler. By now you probably know that clogged EGR Coolers have led to the early death of countless diesels over the years, and I've never seen one fitted to a Ford gas motor. Nonetheless, there it sits. I thought technology had progressed passed the need for EGR on gas motors in general. It appears I was wrong, and 'diesel like' emissions systems are now being fitted to gas motors. Let's hope we don't start seeing Gasoline Particulate Filters ("GPFs") next:

Since the 2.3L EB lacks a traditional exhaust manifold, the cooler connects directly to a post in the head.

It's not nearly as big as the EGR Coolers we see on larger diesels, but the construction is similar to those found on 6.0 and 6.4 Powerstrokes.

That is interesting. I am not sure about the 2.3, but the 3.5, at least the engine from 2011-2016, does not even have a EGR.

They use the cam timing or something as an EGR control.
 
The Toyota Prius has an EGR cooler. Figured it was only a matter of time before gas burners that still us egr valves would have them incorporated into their emissions system.
 
GPF are going to start becoming standard, I work for Mercedes and there are already several vehicles starting in 2019 and up that have GPFs and take diesel specific oil (low ash) in their 4 cylinder turbos.

I use Toyota Prius's in my business and they have EGR coolers and yes they do eventually clog up. In response I devised a way to bypass the cooler without triggering the CEL.
 
How can they get away with using the valve timing on 3.5 but not the others? 3.5 has no egr as I said. They are all DOHC turbo DI engines.

It all depends on what application and the emissions standards they need to meet with that particular vehicle. Since Ford's portfolio has shifted to trucks and SUVs along with emissions standards getting tighter and tighter, expect to see EGR popping up on most Ford engines in the near future. Yes, they were able to get around having to use EGR with advancements in cam timing and DI injection, but there's a certain point where EGR makes sense again.
