Cummins Diesel Rolling Coal While Pulling A Dump Truck

Welcome to 25 seconds of rolling coal my friends. These guys are testing out their truck before they head off to a poor competition. Dump truck serves as the weight that will be towed, and it looks like the Ford is able to pull the dump truck across the pasture with ease. To replicate the pull as accurately as possible, the dump truck has its wheels locked. This means the Ford diesel is dead-pulling the entire weight of the dump truck. However, when we look a bit closer at what is going on, a few questions come to mind.

Is That a Cummins Diesel Under the Hood?

That’s right, is that Ford generating all of that horsepower with a Cummins engine under the hood? By the sound of it, it sounds like it could be. For that matter, by the sounds of it, it appears like it must be. This inevitably will not go over well with the Dodge ram crowd. It seems that even though Ford was using Cummins engines long before Dodge took over, Dodge purists hate to see you a Ford with one of them under the hood.

They feel like it’s sort of cheating, or not staying true to the auto manufacturer. However, feelings aside, it would seem like this is a Cummins engine simply by the sound you hear when it engages. You have that signature not-in-low upon idol, and the hallmark growl upon engaging the vehicle to pull the dump truck. So, question number one answered. This is a Cummins under the hood.

Why all of That Thick Diesel Smoke?

The truth is, it is simply not necessary to blow all of that black smoke into the air, unless you are trying to impress your girlfriend, or don’t know what you were doing. The fastest diesel in the world uses a Duramax, v8 on a Dodge Dakota, and gives off very little, if any smoke. This feat was pulled off by none other than Gale Banks. He is known for doing incredible things with diesel engines. His talent and skill are legendary in the west. With his own engineering company, he set out to produce the world’s first diesel engine that generated zero smoke. He thought it was possible, if certain factors and issues regarding engine performance could be addressed. He and his team took to the drawing board and begin to build this beast from scratch.

Well, he succeeded in not only producing a no smoke diesel, but also producing the world’s fastest diesel engine to date. The Dodge Dakota mentioned in the last paragraph was put to the test by traveling to one of the Bonneville salt flats races pulling its own trailer full of racing gear. It then clocked an astonishing speed of 217 mph, breaking and setting a new record, and promptly towed the trailer full of gear back home to California afterward. You call that truck whatever it wants to be called. You call the person driving it “Sir”.

Oh, I should also mention that the 5.9 L engine nestled under the hood of that small Dodge produces 730 brake horse power. Try that with your standard diesel engine. Furthermore, try to do that and generate no smoke with a regular diesel You won’t do it. It’s just not possible.

The key has to do with airflow and power

If you get those two things to right, then you generate zero smoke. This is what Gale set out to address when he created the engine. However, if you over fuel the mixture, then you will churn out more black smoke than the little engine that could. You need to dial back those high EGTs. Keep them to a minimum and you find yourself running a more efficient engine, which translates into better performance. If your EGT remains too high, you could destroy your turbos, melt a few pistons, crack the heads, or simply create general engine havoc. None of this is good. Think about that the next time you see somebody churning out smoke like a coal miner. It might look good, but it could spell disaster long-term.

Pomp and Circumstance or Pitiful Circumstance?

So, back to the subject at hand. Will this Ford diesel, with a Cummins engine tucked inside, be able to perform well at the pull event? By all accounts, the answer seems to be a pretty solid yes. Many engines blow thick black smoke all the time and have no problem. The truth of the matter is you are always going to have some heat created with a massive diesel engine, there is simply no way around that. The trick is making sure you have it tuned properly, with airflow and fuel mixture taken into consideration. Do that and everything will go off without a hitch, albeit with a bit of black smoke and grandeur. Do it the best, and you wind up with a clean burning engine, breathable air, and first place. It would be pretty funny if this guy showed up and was beaten handily by a truck that produced no smoke. All of that growl and show for nothing.
