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?

Wow a Ford 3.5L went to port see why:

"When a first gen 3.5L EcoBoost hit 100,000 miles carbon build up would become a major issue. Did dual injection resolve this?

The first-generation Ford 3.5L EcoBoost V6 was a powerful and efficient engine. In F-150 trim it would produce 365 horsepower and 420 pound-feet of torque. Some of this power and efficiency was thanks to the use of direct injection. Injecting gasoline at high pressure directly into the engine’s combustion chamber reduces fuel waste while also delivering more power. It is a win-win.

But direct injection has a dark side. A dirty, performance robbing dark side known as carbon build up.

Direct injection engines do not spray any fuel on the intake valves to keep them clean. As a result, what was commonly found was that by the time the engine had 100,000 miles on it there was so much carbon build up that the engine would suffer from drivability issues. Rough running, and loss of power are common symptoms.

To help address this issue Ford came out with a second-generation 3.5L EcoBoost. This engine was not only more powerful, but it also used a dual injection setup.

It is a combination of port injection and direct injection. This was done to eliminate the carbon build up issue.

Did it work? A video recently posted on the FordTechMakuloco YouTube channel examines that very question. An examination of first and second generation EcoBoost engines with similar mileage is done. A port injection engine is also examined for comparison purposes. Did the second generation EcoBoost eliminate carbon build up? No. It does a better job of keeping the valves keep. However, carbon build up is still evident."

A horse of a different color . here is the video:

Result 3.5L 2G ecoboost much clearer and modification to port in 2017 , while Bronco was a star in its mother's eye. Now port in MY 24 3G 2.3L Mustang .Which is built Ford Wild? 1.5L, 2.3L or 3.5l?

This may be grounds for 2.3L 2G ecoboost class actions, if an attorney's Bronco goes to 100,000 miles (12k× 8 years emission test failure) Here is proof positive big Blue Oval knew the 2.3L had carbon issues, but elected to use Mexican produced 2.3L in our Bronco!😥😥😥😥😥😥😥😥😥It's all about RETURN ON EQUITY of stakeholders not its loyal customers!

Ok If Ct. bans, then all blue states will follow. I guess those red states dont give a dam how many tons of CO2 they put into the air. But with global warming, they will be the first to get bad weather events. When the Gulf Steam waters gets to 89° watch out!

Oil vapor is not CO2, its an unburned hydro carbon.
No one says CT regs are correct, its just how they are.Many laws in this screwball state are questionable.

I must be a glutton for punishment for responding, but...

The 2.3l direct injection Ecoboost has been used since 2015 - that’s 8 years. So far, there has been no recalls, class-action lawsuits, or moaning and gnashing of teeth due to carbon buildup on the valves.

In 8 years you will still have a brand-new engine, based on how often you actually, you know, drive your Bronco.

Stop looking for trouble and use it, or sell it to someone who will appreciate it.

I would like to lodge a complaint about the complaints of the complaining complainers, please. 😜

I don't even know what they are complaining about anymore. If I ate popcorn I would have some about now.

So if you want port injectors added, send Ford a letter, I'm sure they will listen to reason.

Today just saw 2023 Vet. Guy say 550 hp but LZ1 specs say 600. Well my 911S is only 365 hp but gets twice the mpg like my Bronco. So who is complaining that set him back $100,000 plus its a 5.5 L engine But not turbo! 2.3L. Maybe I need two engines @300= 600 and one in cargo.

Well let me correct my self. Its 2023 Stringray 6.2 L putting out under 500 440-460 but guess what:

What Problems Does the Chevrolet 6.2L Have?
Some common issues include carbon build-up, lifter collapse, bent pushrods, transmission shuttering and/or vibrating, and a few other smaller problems.
The smaller problems include fuel injectors, fuel pumps, lower intake manifold gasket, engine mounts, and manifold bolts. No car is perfect and I just saved $65,000. I guess I'll keep my 365hp 911S cab for another year!

Just checking my 911s is Multi port fuel injection system. The injectors in the cylinder head but are feed by a fuel common rail which sits behind the intake values. Porsche went to Direct Injection latter on. Carbon build on the 3.8L is minimum on MPFI vs DI

Porcshe went DI to get say 400 hp from stock 355. Advantage hp disadvantage carbon!

If anyone want more technical info I have several books on Porsche, on fourth!

One more article .According to Paul Frere 's book Porsche 911Story my 3.8L has sequential a form of multi port.

Here are differences:

Port or Multipoint Fuel Injection
Multipoint fuel injection devotes a separate injector nozzle to each cylinder, right outside its intake port, which is why the system is sometimes called port injection. Shooting the fuel vapor this close to the intake port almost ensures that it will be drawn completely into the cylinder. The main advantage is that MPFI meters fuel more precisely than do TBI designs, better achieving the desired air-fuel ratio and improving all related aspects. Also, it virtually eliminates the possibility that fuel will condense or collect in the intake manifold. With TBI and carburetors, the intake manifold must be designed to conduct the engine’s heat, a measure to vaporize liquid fuel.This is unnecessary on engines equipped with MPFI, so the intake manifold can be formed from lighter-weight material, even plastic. Incremental fuel-economy improvements result. Also, where conventional metal intake manifolds must be located atop the engine to conduct heat, those used in MPFI can be placed more creatively, granting engineers design flexibility.( This different than 3.5 and 2.3 l Mustang 2024 with PGDI)

Sequential Fuel Injection
Sequential fuel injection, also called sequential port fuel injection (SPFI) or timed injection, is a type of multiport injection. Though basic MPFI employs multiple injectors, they all spray their fuel at the same time or in groups. As a result, the fuel may “hang around” a port for as long as 150 milliseconds when the engine is idling. This may not seem like much, but it’s enough of a shortcoming that engineers addressed it: Sequential fuel injection triggers each injector nozzle independently. Timed like spark plugs, they spray the fuel immediately before or as their intake valve opens. It seems like a minor step, but efficiency and emissions improvements come in very small doses.

Direct Injection
Direct injection takes the fuel injection concept about as far as it can go, injecting fuel directly into the combustion chambers, past the valves. More common in diesel engines, direct injection is starting to pop up in gasoline engine designs, sometimes called DIG for direct-injection gasoline. Again, fuel metering is even more precise than in the other injection schemes, and the direct injection gives engineers yet another variable to influence precisely how combustion occurs in the cylinders. The science of engine design scrutinizes how the air-fuel mixture swirls around in the cylinders and how the explosion travels from the ignition point.

Things such as the shape of cylinders and pistons; port and spark plug locations; timing, duration and intensity of the spark; and number of spark plugs per cylinder (more than one is possible) all affect how evenly and completely fuel combusts in a gasoline engine. Direct injection is another tool in that discipline, one that can be used in low-emissions lean-burn engines.

Our Mercedes Benz CLK 430 had 16 spark plugs. I had S430 great car but thought S550 was nicer. Traded in for Jag XF some say it was a Jaguar engine made in a UK Ford plant.
Have same v8 in my RRS and that is not Direct Injection. AJ133!

Well my Jag has a different type called spray guided direct injection.

Here is a write up from one of the inventors:

"Improvement of Center Injection Spray Guided DISI Performance 2006-01-1001
Spray guided DISI, a next-generation DISI system, is now under development as a gasoline engine which will contribute to improving fuel consumption. The authors have carried out a study to improve fuel consumption and exhaust emissions resulting from a spray guided DISI system with a center injection structure, which is being developed as a system with superior combustion stability. (1&2G Ecoboosts)

The primary issue for the center injection structure is to reduce changes in the fuel spray characteristics resulting from carbon deposits near the injector nozzle holes.

The secondary issue for this structure is to improve the mixture formation.

To address these two issues, the authors have studied the following measures, which have been shown to maintain stable combustion conditions, as well as offer some improvement to fuel consumption and exhaust emissions performance.

(1)Combustion gas sealing at injector tip
Reducing the amount of heat received to the injector tip was successful in lowering the surface temperature and in reducing the formation and accumulation of carbon deposits. This subsequently reduced the changes which occurred in the spray shape and fuel flow rate over time, allowing continuous stable combustion.

(2)High pressure fuel injection and external EGR
Improved spray atomization due to high pressure fuel injection resulted in the suitable stratified mixture for combustion with the center injection structure, and thus improved fuel consumption and reduced HC emissions. The increase in NOx emissions, which resulted from the more active combustion was eliminated by external EGR."
