Water Methanol injection for Diesel?

Is the SCR not downstream from the engine?

 

Heat is generated in the exhaust for regen by an in exhaust injector.

 

I thought that went away once the DEF systems got going

Use to reduce oxides of nitrogen....N0X

A good explanation..

The DPF reduces soot. Period. Regnerations are to increase exhaust temperatures in order to burn off the soot inside the DPF, if necessary. Increased exhaust temperature is done through increase injection of fuel, not DEF. The additional fuel is injected into the exhaust stream before the DPF. Increased exhaust temps will require more DEF in the SCR (catalytic converter) to keep the NOx numbers within spec, so in that sense, DEF is used more during a regeneration.

 

none of your fucking business how I pay for my racing !

and oh yeah - we'll hit Cave In Rock and some other stuff closer throughout the summer.

@rogers1323 -

unloaded etc - varies between 600-800 depending on how hard I’m running.

loaded usually about 200 degrees higher (~800-1000). When I hit a steep grade, I watch EGT gauge like a hawk, if it climbs towards 1200, I start adjusting throttle to keep it in check. Especially if I’m a idiot and don’t approach the grade with proper speed etc.

 

I found, getting better flowing pipes and a better turbo wheel helped the temps in my truck. I also got a afe intake. Open intake with a heat shield and a prefilter cover. When unloaded, my truck doesn't drive like that often, I have a hard time getting to 700. My truck/trailer is heavy, 22k combination, I can easy keep it under 1200 on big climbs as long as I'm over 2k rpm. Lugging the old truck makes crazy EGTs.

On an unrelated note, I have a garrett 38r I'm not using. If anyone wants to offer anything for it. I think I have 2 wheels for it.

 

sent you a text

 

I sent back nudes to that new number you used.

 

you are so wrong man…

 

Did they look like this?

 

You said you wouldn't share them with anyone!!!!!

 

You are hung like a ....stick!
