7.3L Powerstroke Diesel Engine Starts-(T444E International)

[4thstooge]

Unless you are some kind of diesel engineer you will not likely know what parameters the mfr. has set into the design as far as Governor settings are concerned. Labeling an engine as a "piece of junk" is shows how ignorant you are.

[ps3dethman1]

my school bus has the same engine. its a 95 and it's never bin in for repairs says the driver...and its wont go over 65 cause it has a speed governor...now there was this new bus 3 yrs ago that broke down on the first day (locked up)... it had a cummis...thats the only cummis ive ever seen blow up.

[6030diesel]

not a powerstroke! its just a IH engine. the powerstroke engines were common rail injected this engine is rotary ip so its not a powerstroke

[mrfanman2u]

the t444e is the same internally as the powerstroke. The 7.3 and 6.0L powerstrokes also is not considered common rail because the injectors pressurize the fuel with an intensifier piston, fired by the high pressure oil from the HPOP actuated by a solenoid on top of the injector which allows the oil to fire the injector.  They do have a fuel rail that is in the head, but it is not common rail, In common rail injection the fuel is pressurized to the injectiing pressure in the fuel rail.

[WARD5KUSTOMZ]

the powerstroke uses a HEUI system as well as the 444 and other international engines.

[zytekfan]

Powerstroke wasn't common rail until the 6.4.

7.3 and 6.0 used HEUI injection which uses high pressure oil to control the injectors.

[amfan12]

Do tell, where is the rotary injection pump on this engine? Where are the injection lines? Where are the external glow plugs? The only other 7.3 V8 IH made has external injection lines, injectors, and glowplugs. The power stroke has all the injectors and glowplugs under the valve cover - like this engine. Its a powerstroke.

[mr3vil666]

@amfan12 The Powerstroke is just a re-badged T444E. They are made by the same company. A label on the pass side rocker arm cover of my 7.3L Powerstroke even has International's logo on it.

[kiefer1234566767]

@mr3vil666 just different paramiters built into the engine throughout the years because of emmisions laws so they had to run hotter then the school busses

[edgar1531]

esos motores son superrr cool

[Georgejoyrider]

I Ride International Bluebird 3800 it was powered By T444E it was nice

[boizwithguitarz]

What kind of bus is this engine from? a blue bird international?

[powerstrokeking]

Even though this engine was rated for 210 horse power, the engine card on my 95 F-350 powerstroke says 215 @ 3000rpm.

[mongo731]

Only 210 hp? My early 99 7.3 F-350 is putting 320 hp / 704 ft lbs at the rear wheels.

[Robbgt]

Hey, does that have splits or singles? Almost sounds like splits. I know that cali trucks had 120cc splits (ford) not sure that the deal it with international engines though

[imergutierrez]

I SAY IT HAS SPLITS

[BGoode95]

Ah my Vista has a T444E, those are awesome!

[powerstrokeking]

The 7.3 is the best Diesel engine ever made. Next would be the Detroit 60 series then the CAT C15.

[kevinlynch7]

no its not. Cummins 5.9 for clas 2-7 trucks, and theCummins ISX 600 Signiture series by far. Deroit series 60 can suck my balls- no power. A Mack MP 8 is better t 485 HP and 1700 TQ vs. Detroits 515 HP and 1650TQ.

[imergutierrez]

hey dat jmkpns koold suk mi dik sayin dt466 has no balls i have a dt466 dat kan fuk ur mother

[jmkpns]

Is it "DAT" powerful? I didn't know you could get that out of a 466. LOL

[jmkpns]

I drove a moving truck that was empty on I-10 and the truck had the International T444E. You talk about an engine with no guts or balls. The piece of junk would not go any faster than 65, my foot was on the floor. The DT466 isn't much better either. YOU DON'T WANT AN INTERNATIONAL ENGINE, they are the Yugo of diesel engines. Pure junk.

[jiggyboy69]

i have an 1990 cube van (probably the same) and that is true but it will do the same thing if you fill the box to the top with anything i have put over 6 tons in the back and if you knew anything you would understand what a great engine this is they dont need any work till well over 500 000

[jmkpns]

They're reliable engines, but the 444 and 466 have absolutely no get up and go. These Internationals are slower than turtles. Cummins, Cat, or Detroit, now there you go!

[cdemon2002]

That engine may have had a governor on it, typical if it was from a trucking company or a truck rental company. Also the T444E is available with at least three different turbochargers. Also depends on your transmission and differential gear ratios.

If the air filter is dirty it won't go very well either. Did you check to see if it had a governor on the engine? Which turbocharger were you running or was it a naturally aspirated diesel? Did you check the air filter?

[jmkpns]

No governor on it, engine oil is at safe level everyday and air filter is okay,, but I drove a Freightliner flatbed truck with a M Benz straight six and that engine was mighty fine compared to any of the two Internationals.

[cdemon2002]

The T444E is 7.3 litres 175-210 Hp depending on turbo and engine control configuration.

The Freightliner flatbed you were driving may have had the MBE4000 6-cyl diesel with a 12.8-liter displacement and 350 to 400 hp.

Could 5.5 litres be the difference you felt?

[jmkpns]

The Freightliner I drove had a 6.5 Liter straight six, but it was bad ass for a smaller engine and it stood up to any International 444 or 466 I've driven, but for a small diesel, I couldn't get over how much get up and go it had from a light.

[hitower9]

@cdemon2002 our freightliner's 12.8 has 450hp, most are rated at 450

[mr3vil666]

@jmkpns All Diesel engines have governors since they are fuel throttled, unlike a gasoline engine that throttles the air. The T444E being electronically controlled means the governor is just some lines of code in the computer.

Most all rental companies will set a Diesel engine to run no faster than a set road speed. Also if your moving truck had an automatic transmission Allison 3 speeds aren't geared for going 70mph.

[jmkpns]

@mr3vil666 I drove a GMC Duramax with Allison transmission and it drove like a dream. Nice riding and nice driving.

[2strokedetroit]

@cdemon2002 I beleive the governor would be in the pcm, so not visible

[ICDave]

ITS CALLED A GOVERNER!!

[onionman113]

@jmkpns my dad had an internation and it wouldn't go any faster than 80 MpH so i'm assuming tht was good for his truck

[jmkpns]

@onionman113 The one I drove didn't go past 65 with no speed restrictor on it. Internationals are slow trucks regardless of size.

[onionman113]

@jmkpns his engine was rebuilt so... yea idk

[txgp17]

@jmkpns You're criticism is useless if you're not also telling us what kind of transmission, axle ratio, and tires you were running.

I used to drive a truck with a T444E in it that wouldn't go over 65 either. The problem wasn't the engine, it was the transmission. The buyer got the cheapest transmission they could, an Allison AT545, and it didn't have an overdrive.

I saw a similar truck with a T444E with an overdrive transmission, completely different driving characteristics.

[jmkpns]

@txgp17 You make a valid point about the transmission, but point is, any International truck I have driven old and new did not have any get up and go whatsoever.

[txgp17]

@jmkpns Define "get up and go." I drive a Detroit 60 everyday at work, mated to an Allison 4000, in a chassis that only weighs 36,000. Sure it has GU&G, but look at how much that drivetrain costs, and the power/weight ratio!!!

I've driven plenty of Int. trucks with get up and go. It's all about torque/weight ratio, and the gears you're using.

BTW, my daily driver has a International in it too (Ford Power Stroke), and it has lots of this so called "get up and go."

[mrfanman2u]

This is a later engine, can tell because of the sound of the injectors. It has Split Shots.

[ICDave]

I WANT MORE OF THAT ENGINE

[01ltlb7]

try powerstroke

[ICDave]

Many of our school buses have that engine, is there another name for it, I cant seem to find many sound clips of them.

[cdemon2002]

I believe the engine is made by International Harvester, and Ford buys them from IH and calls them the Powerstroke. Oil pressure from a high pressure oil pump(3000psi) drives the injectors, rather than an electric or belt driven injector.

If you need a longer sound clip, download Wiretap for the Mac and you can loop the sound to make it longer. You can have a continuous Powerstroke diesel sound playing in your repair shop while you work -no smoke either.

[Hotrodx199]

Yep. International Drops there motors into the Ford F-250's and F-350's. the truck itself is made by ford. the motor made by international. International i think has put there diesel motors in Ford since like the early to mid 80s. its just like the 6.2 and the 6.5 Diesels in the chevys. Detroit Diesel at the time put them into the Chevy K20 and K30 models. Detroit at the time was with GM i believe. Now Daimer owns Detroit diesel and is no longer with GM as far as i know.

[BLCKCLDCTD95]

ehhhhhhh the 24v cummins sounds better!

[cdemon2002]

Thanks, I'll look for it on Youtube.

[Lycan2026]

Love that beautiful sound!
