New Engine Technology; EGR systems, DEF, DPF

Yeah, I think the key to reducing some problems is working the snot out of the emission engines. I also read an article some time ago, that winter fronts in cold weather are more critical to keeping the emission engines from developing problems.

 

I think idle time is what cause's the majority of the problems.

 

On a recent visit to my Detroit shop, we discussed this very subject (DPF EGR).
Mine is a 2009 WS with a S60 in it.
I have yet to hit the regen button.
My average load is @90-100k lbs, and I have a generator. Since July of last year, it has idled 7 nights in total.
My DPF filter is brand new visually. It does regens while rolling down the road.
The guys that have the most problems are those that haul light loads and idle a lot.
Yeah I would rather have a Pre emission S60, but the times they are a changin....

It's the major factor. I've had Detroit tech's tell me that the quickest way to screw up the system is to idle....

 

Could be there a changin..... but that is why I got a glider, so I could still use a pre-egr S60. Those times may be a changin.. but there is no mandate yet that one has to change with it, except for California, which is outside my operating area anyway.

 

Give the infrastructure five years the new fuel will be DME.

Well, high hopes again, but with little incentive to switch. DME is still a gas like propane, has 50% the BTU content of diesel, so in theory would require 50% more fuel for a given run, and DME weighs in 2.5 lb heavier per gallon than diesel. Not exactly what a lot of folks are looking for.... twice as much fuel to go the same distance as diesel while the fuel weighs in 32% more per gallon. And considering it will theoretically require twice the fuel to go the same distance with DME, take a look at how much diesel is used now in the U.S. DME doesn't stand a chance other than in the local markets. We basically see a repeat scenario of how NG was going to save the world.

 

LNG and LPG has its niche... I think you will see it more commonly used for daycab runs and the like. I think a lot of the reason we're not seeing it that widespread now is that there's a bit of skepticism not so much about the systems themselves, but of how .gov will react to it... the same organization which claimed diesel was a heating oil in order to jack up taxes on it. If CNG/LPG takes off, I'm sure we'll seeing efforts made to make the prices comparable to diesel. And some of that is already in play... if you have a company yard, and you want to set up a fueling station, you're probably looking at 10k or more in fees and permits before you can build. Then, if you want to work on them in your own shop, you have to reconfigure the climate control system in your shop... over time, as is, it could be worthwhile, but there's the matter of what's going to happen when .gov realizes the revenue they're losing from conventional fuels... they're not just going to shrug their shoulders and say, "well, I guess that's that". Two things they'll do everything in their power to ensure... that they get their cut of the $$$, and that they keep the industry in a stranglehold.... people who say drivers are the ones in control of this industry are delusional. But that's a whole separate topic in itself.
