Significant changes to the 2025 2.0 Ecoboost Engine

[Phimosis]

Unfortunately all the manufacturers rushed out the door with GDI without considering the consequences. It has just taken some of them A LOT longer to get around to correcting it. People are like, but my truck runs fine... Give her time. Atherosclerosis takes time. She is getting plugged up. A catch can or in this case a side reservoir area in the engine only slows the effect. So now we are back to injecting fuel into that intake. But since they still insist on direct injection the particulate matter issue still exists which forces them to deploy the GPF. Port injection alone doesn't have this issue. Seems like 1 step forward 2 steps back.

It’s the opposite, 2 steps forward, one step back.

Direction injection is amazing for its quench effects. Quench lowers cylinder temps, which reduces detonation, which allows for increased compression ratio and / or increased turbo boost, which increases the thermal efficiency.

There is no way we will just go back to port injection. The HP numbers would go down and CAFE numbers would go down.

Port injection + direct injection is just a stop gap until they can figure out how to fine tune the direct injection alone to get complete air/fuel mixing. Incomplete mixing = incomplete combustion = soot formation.

GDI = improved performance
GDI = oops we forgot that we are dumping sewage in the intake.
Many years later, oops still dumping sewage in the intake, maybe we need to dump some fuel with a detergent on the intake valves so we don't choke these things to death.
GDI = oops oops we dump more fine particulate into the air than a diesel now, so now we have to include a GPF

You are not going to make your CAFE numbers this way. 2027 the next big hammer comes down with the EPA.

It isn't the port injection isn't efficient. They would still make the CAFE numbers, they just won't produce the same power.

For the moment we have a choice. I know which one I am choosing.

Hey Master Blaster, "A catch can was never needed, as there has always been one built onto the side of the block on all 2.0 engines since 2013".
((Do you have a part # or a pic of this catch can??))
Thx...

Here you go, from the service manual:

I think the biggest news on engine is port injection added. No more oil catch can needed. No more dirty intake valves.

I will greatly improve it, for sure. It hasn't completely solved the issue on other Ecoboost engines.

That’s a big nope. Each point you go up in compression ratio increases fuel economy by 5%. The biggest advantage of GDI is that you can run 2 points higher of compression ratio.

The primary reason we use GDI is to reach CAFE targets.

If you have ever run a diesel you then know as soon as that regen fires up your fuel economy is out the window. They aren't going to make their CAFE numbers with the GPF. Something is going to have to give.

They’ve been running GPF’s in Europe for 8 years. If you drive normal, the GPF will regen without richening the mixture up. Gas engines burn hotter than diesel. New GPF equipped vehicles in Europe get better fuel economy ratings than pre-GPF vehicles did. Progress marches on. There’s literally no one that is ditching GDI for port injection.

Man you got some good Koolaid. Well we will see. You know people are running that 2.0 Ecoboost that is reconfigured to run on that GPF right now? Right? You hear anyone saying their fuel economy is UP? And they don't even have the GPF on theirs. I think you need to go take another look. Yes, I have a diesel and I know what I am talking about.

Next you’re gonna start telling us that we have to refill GPF cars with GEF fluid. And you know what you’re talking an about because you own a diesel.

You really don't know anything about this do you?

Admins can we close this topic. I think all that can be said without becoming a problem has been said. Thanks.
