Best diesel engine

There will be other opinions on their views, but good info on each brand and engine series. May be useful to some looking for a coach or conversion.

"Worst Detroit Engine: All old two-stroke Series 50, V-71 or V-92, technology. "


Hurt my old bus's feeling.

Yes the 2 stroke Detroits are past their prime. But-that's mainly because no technology was used to upgrade them. I can imagine what the engines would be like with electronic common rail fuel injection.
Strange though how 2 stroke Detroits have been cast aside as being the dirty engines. Yet virtually all big freighter ships carrying overseas containers use giant 2 stroke Diesels of the basic same design principal as the old Detroits. But of course they are much bigger. So instead of a 4.25" bore (71 series) or a 4.85" bore (92 series) with a 5" stroke, the biggest series has a 39" bore by a 135" stroke (yes over 11ft!)-but only turns 82 rpm. 82rpm on the large engine is like our 5" stroke engines turning 2,214rpm-piston speed wise. Good Luck, TomC

Methodology for arriving at conclusions?

However, for those with low blood pressure problems, it is a good read to get yer blood pressure up?

happy coaching!

The two cycle is being phased out in locomotives also. Although Norfolk Southern is adding new life by upgrading the amount of emissions generated. Probably also done by other railroads and companies as well. Now that Caterpiller owns EMD locomotives, their interest is in using four cycle engines in future models. Who knows what will happen with GE locomotive business.
Detroit two cycle engines will always have their place in history, but technology moves on..their eventual demise hasn't been helped by political crusades either.

Being that CUMMINS is standard in most MCI buses now, that says a lot.
It never crossed my mind that I own stock in them:)
The old DETROIT 2 strokes were pretty much indestructible for just about forever and no mistaken the sounds.
I wonder if this new experimental opposes piston engine will find its way to buses.

When did a series 50 become a 2 stroke

Just wondering

Perhaps he meant 53.
GE sold their locomotive business last year  and I think it's called WABTECH or something to that effect.

I would say the methodology involved a younger less experienced person, a lack of research into the history of the engines, and preoccupation with the cost and ease of overhauling current engines. Mack engines were not given enough credit for the older models, and Detroit 2 cycles were not given the credit they deserve in history. They predominately powered the winning side of WWII, and no engine has ever sounded better, in my opinion. The CAT 3406, Cummins Big Cam, Detroit Series 60, and the DT466 deserve credit alright, but not at the expense of dissing 2cycles.

They are just speaking about a electronic engine they way I read it the 3406 -425 hp IMO was the best ever made the first million mile engine built, the driver could not hurt that engine lug it down to 900 rpm press the pedal when the smoke cleared you were off to races

I like the fact that when I lost an alternator pulley on a trip I finished the 1500 mile leg of that trip just by running during the day and charging the battery at night.  My engine doesn't need electricity after it's running.  There is a side of me that really likes that.  I just ditched my pickup with a Powerstroke diesel and in the spring I'm going to look for an Arizona pickup with a regular cab, a long bed and a carburetor...  Straight six and three on the tree bonus points!  Clifford, you got one of those?

Many would contend that NAVISTAR built the best diesels.
That had much credibility many years ago but how times have changed.
The FORD/POWERSTROKE issue was just one of the laughing points.
KME offered MAXFORCE engines in their apparatus about 15 years ago.
They were out of service so often that depts. who actually ordered those lousy engines sued.
Needless to say, it appears that NAVISTAR is getting out of the engine business since they offer CUMMINS engines on their skoolies for diesels and PSI for their gasoline and propane models.

I love my 3406 e

The cost of certifying engines to meet current and future emission standards has winnowed out to only the manufacturers with deep pockets.

[CrabbyMilton]

Well if you build lousy engines, your pockets won't get very deep.
