Going to run an experiment today

I have a test vehicle in the shop. It’s a class A diesel pusher motor-home powered by a 450hp Cummins ISL. The truck is 2010 emissions compliant with DPF/SCR combo and DEF. I was talking with a co-worker and we wondered how long the engine would run, solely on its own exhaust.

So, I’m going to start the engine on atmosphere air, then hook and exhaust hose from the SCR directly to the intake and see what happens. They claim that the exhaust coming from this set up is cleaner than the air it’s taking in when it’s run in high smog cities.

Stay tuned!

OK we ran the little experiment.

It only took me a few minutes to rig up a box to feed the exhaust gas into the intake plenum but it drew a lot of attention for the engineering staff as to what would happen. The engine already has an EGR system but we just made it 100% EGR.

There were numerous theories on what would happen including:

Wouldn't run at all - would run for 5 + minutes - no change - check engine/stop engine lights

The experiment was only run at idle.

So what do you think was the result? I wanted to see what other's opinions were before I told the results.

I bet it ran decent. Maybe not as well as with the cool air. But definitely ran.

i'd bet in a completely closed system it wouldnt run very long at all, as the original starting air is only 20% oxygen, it won't take very long to deplete.

I agree - With burning the oxygen (one of the needed components for fuel burning), it isn't going to run well very long. It will start running like crap until it dies.

This all started as a joke. An engineer said "If these engines run so clean they should be able to run on their own exhaust". That started the gears turning with a co-worker and I. I figured let's try it. Here is what our little experitment looked like.



Simple yes but I do have a masters in cardboard and duck tape .

I thought it was interesting and should share with my diesel buddies. We need a little more input before I tell what happened. Some are on the right path though!
