PORT FUEL DIRECT INJECTION COMING TO 2.3L EGO BOOST SOON

Here is how Toyoto did Port Fuel Direct Injection on 4 cylinders:

Toyota Direct Injection? Port Injection? Why Not Both?
Port fuel injection and direct fuel injection systems each have their advantages and disadvantages.Toyota calls this system the D-4S or Dynamic Force Engine

The direct fuel injectors are just like any other direct fuel injection system. And, the port fuel injectors are not there to clean the intake valves; these injectors work to provide fuel to the engine. Both sets of injectors work together for the best possible fuel mixture in the cylinder.

Port fuel injection can offer better vaporization under certain conditions.

Toyota uses its blended approach of port and direct fuel injection to give the best possible performance, emissions and economy.

D-4S Engines The latest vehicle to get it is the four-cylinder used in the 2017 Camry. The best way to spot one of these engines is to look for port fuel injectors and a high-pressure fuel pump.

How It Works
According to Toyota, during low-to-medium engine loads, both direct-type and port-type fuel injection are used together, or one of them is used to create homogeneous mixed air and fuel, thus contributing to stable combustion processes.

During high engine load ranges, only the direct-type fuel injection is used to cool down the intake air with the chilling effect of vapors in the fuel, which is injected into the cylinder, improving charge efficiency and anti-knock properties. Under some conditions, the intake valves open to allow the homogeneous air/fuel mixture into the combustion chamber, and fuel is injected during the first half of the intake stroke.

During a cold start, the system times the opening of the port and direct fuel injector to decrease emissions and achieve stratified combustion. Immediately after a cold engine start and during the exhaust stroke, fuel is injected into the intake port from the fuel injector assembly (for port injection). Fuel is also injected from the direct fuel injector near the end of the compression stroke. This results in an air-fuel mixture that is stratified, and the area near the spark plug is richer than the rest of the air/fuel mixture. This process allows a retarded ignition timing to be used, raising the exhaust gas temperature. The increased exhaust gas temperatures promote rapid warmup of the catalysts and improve exhaust emission performance.

It is impossible to detect where the changeover from port to direct injection occurs. The only way to see the different fuel injection operations is with a scan tool.

The ECM controls the fuel pump and calculates low-pressure fuel demand based on vehicle state and the signals sent from various sensors and outputs signals. Three-phase Pulse Width Modulation (PWM) control is used for the fuel pump control ECU.

Both injector sets use the same fuel pump in the tank to provide fuel pressure to the fuel rail for the port fuel injectors and the high-pressure fuel pump on the engine. The pump should produce 51 to 73 psi while running and five minutes after the engine has turned off. If the pump is not working, both systems will not work.

The high-pressure fuel pump can generate 435 to 725 psi.
The system offers the best of both worlds while avoiding carbon buildup on the intake valves. Other manufacturers, including Audi and even Ford, are adopting the Toyota D-4S dual-injection system. As the costs of the components decrease, look for these types of systems on even more engine applications.

Since Ford is using this system on 2024 Mustang 2.3L ,when will Bronco have Port Fuel Direct Injection to help with carbon issurs?

Here is some info from Mazda, the forerunner of Ego Boost 4 cylinders:
What is Direct Injection?

Direct injection is a form of electronic fuel injection (EFI) where the fuel injector sprays fuel directly into the cylinder, as opposed to port fuel injection, where the fuel is injected into the intake tract ahead of the valves and after the throttle body. Direct injection offers many benefits over port fuel injection, including increased power and fuel economy, due to it's ability to contribute to an extremely lean burn. Direct injection engines require a high-pressure fuel pump to create enough pressure to properly operate, and use a common rail fuel system.

Carbon Build Up Problems>

Direct injection is actually a fairly old technology, with the 1955 Mercedes 300SL using direct injection, and diesels using DI for quite awhile. Gasoline DI only became mainstream around around the early 2000's, and many of these early engines had issues with carbon buildups forming on the intake valves; an issue that was rather uncommon for other EFI engines. The reason for this is fairly technical, but I'll shorten it for clarity and provide a link that explains it in more detail. Basically, combustion byproducts get recycled into the intake tract through the PCV valve, and will cling to the intake valves on their way into the combustion chamber. With port fuel injection, fuel is constantly moving over the valves, in effect "washing" the valves and preventing carbon form building up too much. With DI, the absence of this fuel allows the carbon to accumulate, and if left unchecked, can prevent the valves from seating properly, causing a number of issues.

How to Prevent It

Simple: rev the crap out of your engine.

No, seriously. Mazda was one of the first auto manufacturers to put direct injection into mainstream (read:economy) cars back in 2005 with the 2.3L DISI engine. They've been messing with DI for awhile and so they were obviously aware of the issue when designing the Skyactiv-G engines. What they found was that carbon deposits form when the intake valves get below 400*F, so when designing the block and cylinder head, they routed coolant passages away from the intake valves to keep them above that threshold. You can do your part by taking your car out on a nice drive and putting the engine through it's paces, and taking it up to redline a few times.

Some call this an "Italian tune up".

Oil Catch Cans

An Oil Catch Can is a container put in between the PCV valve and the intake manifold that separates oil and water, preventing it from going back into the intake. For many cars, it can reduce (not eliminate) the potential for valve deposits forming. It is very much a beneficial mod, and I would recommend it to anyone who plans on keeping their car for an extended period of time. However, don't let other people say that you "need a catch can", because, as I discussed above, the issue already has a solution that doesn't cost you $165.

Some say and Ford parts confirm that the Bronco has a oil separator build in so a catch can is just added insurance.

If you can unscrew the intake tube,(s) you may see oil. Just clean with rags.

Here is the Bronco oil separator part ,# K2GZ-6A785-A MSRP $54.33 See below but no filter like $300.00 below performance..Now the factory separator is just a series of baffles that repeatedly change the direction of flow slowing it down and causes the oil vapor to collect and drain back into the crank case. Depending on the port sizes for the drain on the side of the block it may be possible to modify the separator by adding a bit of large coil stainless steel wool like the type used in food service. No corrosion or rust issues and it would significantly increase the contact points for oil vapor in the PCV air stream passing through the separator, and improve its performance .

Ford does not consider this a required maintenance item, but reports are they may get clogged from hot and cold and gum up like a PCV.

Here is what is reported. Oh I use a $50 Fire and it spell words all different ways. I just bought Eggo or is it Eco or Ego. Whatever! Some members have those ego's that need boosting every once and awhile. Here goes:

Next-Generation 3G Ford 2.3L EcoBoost Engine: Details

"YouTuber Stang Mode was able to document many of the major changes found in the next-generation 2.3L EcoBoost engine in the 2024 Ford. Regarding the internals, there are new pistons, new connecting rods, new camshaft, new fuel delivery system, new air induction system, and an electronically controlled turbo present, to name a few. (3G EcoBoost)

Those new pistons and rods help bump the compression ratio up to 10.6:1 from 9.5:1. This also suggests that the engine requires less boost to reach its horsepower and torque numbers, potentially leaving room for tuners to increase the pressure and add horsepower, provided they can pass the locked down engine control unit.

Speaking of boost, the turbocharger is now a twin-scroll unit with an electronically controlled wastegate, and the engine will also now use internally plumbed exhaust-gas recirculation (EGR). While EGR is known for reducing emissions, it’s also been known to shorten the lifespan of an engine, so we’ll have to see what sort of measures Ford engineers took to mitigate that.( Less carbon buildup ?)

Finally, the direct injection fuel pressure of the EcoBoost is being bumped up to 5,000 psi and will be paired with port injection for a dual-injected setup.( helps lower carbon build up)

Despite all the fanfare around #savethemanuals, the EcoBoost will not be offered with the transmission option at this time. Instead, it will be paired solely with the 10R80 automatic 10-speed auto.(10R60 is limited to around 400ft lbs)

Official horsepower and torque numbers still elude the S650 ... EcoBoost, but the expectation is that we are to see more than the 332 horsepower and 350 lb-ft of torque that was in the S550 ...EcoBoost HPP. Can we get 350 hp, 400 lb-ft, Ford? Please? Yes!"

From a mustang to a bronco, the horse is out of the barn. Why buy a Raptor 3.0L when a new 3G 2.3L EcoBoost will be pared with stronger transmission and tuned to say 400 ponies?

Here is another post but on Ford Authority site( sorry Laura) on carbon build up worry:

"Modern vehicles have a PCV system, which is a form of emissions control. Essentially the extra air in the cylinder that blows by the piston rings and into the crankcase gets recycled back to the intake system. Obviously the crankcase has a lot of oil in it, and therefore that some of that oil gets mixed with air that gets sent back into the intake. That air with tiny oil droplets gets stuck in the intake and on the back of the intake valves. Over time this carbon buildup can restrict airflow to the cylinders and reduce performance.

Normally this isn’t a gigantic is issue because fuel is a solvent and will clean the intake valves as it is injected into the intake. The problem with the 2.3L engine is it is a direction injection engine—fuel is injected directly into the cylinder, thus bypassing the intake. Therefore… no cleaning.( Will adding a port injector help?)

So obviously the engineering challenge is to remove the oil from the air that is recycled from the PCV system. Enter catch cans. They are designed to separate (or catch) the gunk in the PCV air to help ensure the intake remains clean.

So why is catch cans so controversial for many people on this forum?? Because Ford has oil separators on most (all?) of their direction injection engines, including the 2.3L engine in the Bronco. Therefore some people think catch cans are a waste because Ford already solved the issue."

I'll wait until the 3G 2.3L eco boost arrives . If want more ponies the v8 is the way to go, but that lower Ford fleet mpg. But when EV goes into high production , a v8 will be put in our Bronco. Dark Horse 500 hp sounds nice. But had 4.5l twin turbo and that blew two quarts of Mobile one every hard run. But at 450 hp and 450 ft lbs it was fun!

I run an oil catch can on my 2.3 "ego" boost engine, and I can tell you that it does catch a fair amount of oil, too much in my opinion. The fact that the catch can is doing its job in catching those oil droplets obviously shows that Ford's oil separators do not do the job they are supposed to.
