DEF/DPF Trucks...GOOD or BAD?

Understand completely,

Since the banks would not listen to my pitch on the first, second and third round I went with private capital investors. The lending institutions balked and said it never would work, I had a grand total of 135k to work with which included my first 5 months of operating expenses factored.

I was on the road and rolling legal for half that and paid the loan off in two years and the contract was for 4 years. Second truck in two years and two more trailers also.

Bankers have no clue what they are doing except to be a bean counter.

My personal opinions only

 

I have never seen any evidence of that. For instance, even though CARB has required emissions testing of autos for quite a long time, most of the rest of the country still does no emissions testing, and have no plans to implement such testing. There is no other state that is requiring anything remotely like CARB regarding heavy trucks. Sure, some like NJ are occasionally doing testing on opacity of exhaust and such, but there is no requirement to meet any emissions other than the year the engine was made. No other state has required retrofits of emission equipment on any vehicle, large or small. True, emissions levels of newly manufactured engines has gotten tighter and tighter thru EPA mandates, but only on new production, not on existing engines. And no state (other than CA) has mandated any engine clear back to the early 1900's be removed from use on the road. And the EPA still allows a new truck, in the form of a glider kit truck, be equipped with a rebuilt engine from a previous year and that the engine only meet the emissions requirements in place at the time of its original manufacture. And I know of no state (including CA) that will not allow you build any auto, from scratch in the form of a "kit" car, and register it for legal use on roads. It only has to meet certain safety requirements of all motor vehicles.

True, some port authorities have followed CARB ideas, but that is hardly the rest of the country. And even if the rest of the country followed CA regarding emissions, I will get all the use out of the new glider with pre-emssion engine I have on order before it is outlawed. The vast majority of states will grandfather instead of out right bans on engines. There may be a future elimination of allowing gliders with pre-emission engines, but since it isn't mandated now, I am not going to worry about what "might" happen. If I did that, I wouldn't do anything for fear of what "might" happen.

 

Here is the evidence. Maybe they will change their minds another few dozen times between now and 2023. Currently though, this is what's required to run Ca. until 2023.

 

neither one of you really read the previous posts did you?


Because that's what I uploaded in my first post here.

 

Sure I did. I saw at the bottom of the pdf you attached that it was revised in Jan of 2011. Please compare the two and I am sure you will notice the differences.

 

Back in '07 I heard that the idle should be set up to 900-1000 rpm during an extended idle time. I have never verified this with a KW rep, but the results have been good on my end. This has seemed to help especially for an '09 KW which never went to the shop with a DFP problem during the year I had it. Talked with a lot of others who did this with good results, but a lot of others who have never heard this. I wonder if anyone else does this also?

 

we run APU's and rarely have issues with DPF stuff.

 

Invalid answer.

The link you posted does not give any evidence of the other states following CARB, which was the original answer to the comment that the rest of the states eventually follow CARB. I did state that the EPA has implemented some engine emission requirements that were originally mandated in CA, but that is for new production engines, NOT EXISTING ENGINES, like CARB wants to do. No other state has or is considering mandating retrofits to any existing engine. And neither is the EPA at this time. My comment still stands.... I have seen no evidence of other states following CARB requirements in the past or considering doing so in the future.

Time for a remedial reading class.

 

To clarify this, the '03-07 trucks that got the first round of emission programming & egr's had tons of issues. Less than the average mid 07-10 DPF'd, but still expensive repairs, shorter engine life all due to the EPA sticking their hands in the mix.

 

I've thought about this too, a lot of people have a lot of issues with the dpf system. Although they never really say how much they idle, and how much that idling is at less than 900rpm.

I know if you keep idling to a minimum and the EGT's high, you shouldn't have many problems with it ya know.

I hardly ever idle my prostar, when i do idle its at 1,000rpm. I've never had dpf issues or had to do a parked regen.

Hows your cascadia been?
