An interesting tidbit...
 

...from fleetowner.com

Yeah I heard about that.

I don't think any APU's will be allowed to idle!

So the "idle police" have a way to measure grams-per-hour?

Is that called... "job security"? :lol:

The engine will have a CARB sticker on it.

This opens the door for after-market particulate filters. Wonder if it's possible to route your exhaust to a stand-alone filter when you need to idle in Calif.?

You've obviously never seen CARB working the scales. If you go through one when they're working and you have soot on your stacks, you might just find out how they do it :lol:

NOx is totally different from soot.

There's nothing you can really do about NOx.

The soot on the stacks is just how they usually decide who to check out. Most of the techs equate a dirty stack with a dirty engine. And actually, it is a good indicator for malfunctioning emissions controls.

My APU is a Tier III which passes the emissions. Even if you have an older model they will phase them out over a period of 5 to 7 years. It's not like they will pass a law overnight and everyone with an APU has to throw them away.

your rigmaster has a DPF on it?

It needs to be tier 4a or something like that.

If you do the research Tier III is as good as it's going to get for APU's. This applies to all engines up to 175HP. If you have a Tier III APU then your good. All others will be phased out over a period of time just like the old trucks. They don't do this overnight.

You're correct, you don't have to worry for now. However any truck with a 2007 year engine needs a DPF equipped and tier 4 approved APU. I don't think there are any on the market right now.

No, that's not correct. Their are no Tier 4 and none planned for quit some time. All 2007 APU's are tier III and that's the state of the art. 175hp and less will remain tier III for some time.

Well, I'll be dipped. When I talked to Rigmaster they said they weren't doing it because the law is only applying to engines greater than 175 HP.

They went from Tier II to III to 4a in one year!!!

PWND

Steve it only matters in cali if you have a 2007 engine. If you don't it's irrelevant. I'm sure in the future it will matter, however there will probably be upgrade kits.

I'm sure when you bought the unit, rigmaster wasn't aware that cali was going to change the rules again.

I'll just stick one of my pandemic face masks over the muffler.

or just not go to stinkin california
