Catalyst converters on semi trucks is the future

Riiiight

 

2004 cat trucks had them too most got replaced by a standard muffler . Those things weighed a ton when plugged lol

 

well, with the high theft rate of catalytic converters, right on the dealers lots even, and in your own driveway, for the precious metals inside them, i say GREAT, let the thieves get in on the trucking industry too..!!!!!!

this ought to be fun. o/o's will have to install plates to cover them from thefts of those now too. and trucking companies will have to weld plates all around them to stave off thefts as well.....i seen a BOOM in the welding trades.

 

Emission requirements are based off of the HP rating, not the fuel type the engine burns. The allowable emission amounts in PPM are different as you cross different HP ranges.

Tier 4 engines under a certain HP rating can meet the emission targets by simply using a catalytic converter. Lots of those little light towers you see run a little 3 or 4 banger Kubota with a catalytic converter.

Move up to a big diesel like Cat uses in their 797F haul truck. SCR catalyst and a Diesel Oxidation catalyst. No DPF. Doesn't need it since the engine emits a low enough amount of particulates to not need it.

Emission Standards: USA: Nonroad Diesel Engines

 

See the issue you folks have is you keep putting the cats back in

 

I meant the catalytic converters. Can't steal what's not there.

 

My head hurts after reading this. I’m going back to my beers after a very long Monday.

Whirly-pop is getting fired up…….

 

If they'll cut the catalytic converter out of the vehicle what makes you think they won't also cut the cage surrounding it?
