DPFs, EGRs, DEF, etc...

Well in theory. We had an inline god at the ranch for awhile. Could not keep ball joints on it and the 68Re was a bag of marbles.

In reality, Inline gods have a hard time being simple and awesome when their chariot is a bag of trash.

Inline 6 diesel vs V8 diesel

So which is the best diesel in a 3/4 ton or 1 ton pickup, the 6.7L Cummins inline 6 in the Ram, the 6.6L Isuzu Duramax V8 in the Chevy/...

any thoughts on your own? I can google too.

Interesting debate. Lets use the 71 series Detroit as an example. You could get that in an inline or v configuration basically the same parts. You went to a v8 71 as opposed to an inline 6 71 for horsepower. At the time you could not get the horsepower out of an in line 6 with out it getting to big and heavy. Ever seen a KT series Cummins! So in the automotive applications they went to a v8 configuration for a while. They needed to be able to get the horsepower in a small envelope. Under the hood of say a pick up truck. Hence the 7.3 power stroke or IH's 444e. The early 5.9 Cummins in the dodges we pretty under powered when you compared to a 7.3 power stroke. Jump forward to today. With the fuel and air delivery control they can make the horsepower out of an inline that you used to need a v8 and with everything they have to hang off an engine these days the v8 doesn't have the real-estate an inline has, not easily anyway. Hence the the 6.4. You take the stuff off crank it up and the horsepower to weight if kinda nice.

My two cents

The 5.9 and the 7.3 were always fairly comparable across the same timeframe especially considering the displacement difference.

Except in HP/Litre, and use in heavy applications.
In those 2 categories, Cummins is superior.
Look at the connecting rods some day and decide which one is stronger.
Power-wise, I’d say they were comparable as engines, but the Cummins had more HP/TQ per litre.

Never saw a Powerstroke in a farm tractor. Says a LOT

Why I bought our LS P7010C over other tractors of similar spec. Mechanical direct injection, turbo, muffler... Last of the Interim Tier 4 engines. Hope it is the last tractor I need.

a way to avoid all this: used equipment. Even if you have to buy a book to maintain it, the power and frankly usefulness of older equipment keeps you grounded. Overall cost is also a fraction of new equipment.

My Tier 3 L5740 was with me for 4 years, replaced by my Tier 4 L6060 which is now leaving after 5 years. Neither had any engine problems except for fuel filters plugging before the scheduled replacement time (yes, we don't get the best fuel in our area). The L6060 did impress me with how much better performance was for only 3 HP advertised difference. I credit that to direct injection. Another farming season past and the only engine powered machine on my farm with an engine issue continues to be the Cummins on my '92 combine. My other 5 are all Tier 4. But I am just one small user.

Interesting how this thread devolved into the relative merits of the 3 main diesel platforms (powerfully argued by the adherents of each of those 3 great religions). To respond to the OP topic, I too am fully supportive of environmental protection policies. However, these particular (no pun intended) policies are somewhat hypocritical and a clear example of unintended consequences. The inefficiencies offset much, if not all, of the benefits. When the DFP failed in my ‘08 Dodge, I opted to delete and re-chip rather than replace the DPF—basically on the advice of the tech that it would extend the life of the engine and turbo unit. He said the Cummins should get 500,000 Km’s before major work, but that with the DPF units they were seeing that cut down to closer to 300,000 or even less. He mentioned a possible improvement in fuel economy. As it turned out, economy went from 650-700 km per tank (consistent from the time it was new) to over 1000 km and even over 1100 when unladen/highway driving. How much particulates were released into the atmosphere extracting, refining, and transporting those extra 300-400 km worth of fuel for each tank?

Found some confusion in this thread.

DPF - Diesel Particulate Filter, all diesels including tractors over 25.5HP

DEF - Diesel Exhaust Fluid, dilute Urea in water to be injected after the DPF into the SCR. DEF is not a part on the machine.

SCR - Selective Catalytic Reduction, The SCR is usually equipped on equipment over 75HP. Uses the Ammonia NH4 to react with NOx to create N2 and Water.

The current emissions units work very well, due to experiments at personal owners expense for over a decade now.

I think the biggest and only rub to have with emissions control is that US government owned equipment still is exempt.

Deleting would not have become an enforceable issue, but the rolling coal for attention crowd painted a giant crosshair on the themselves.

My 2010 cummins is H&S deleted and runs great still, 2011 cummins was sold at 460,000kms with original emissions and no issues, 2018 cummins with DPF and SCR is great, adding DEF is only a minor trash creating inconvenience. But they finally have a bulk nozzle at the cardlock.

Fumeless exhaust is not a bad thing.
