so.... did you apply for the volvo DPF ?
We are gathering bids and working on the application. We intend to submit it before the deadline.
what kind of warranty will it come with ?
Unknown
any thought about expected drop in fuel millage ?
Unknown until the unit is installed (assuming we receive the grant money, but that is in no way guaranteed).
any other engines can be modified ?
D60 ?
I do not know. We are looking at this only for our application.
----------------
There are many unknowns at this point. The first step is to apply for the grant and see if it is awarded. If it is not, no other action is needed. Our truck is CARB-legal now and will be for several more years without modification.
Research done today gives us an idea of what is coming but nothing can be planned that far out. Technology changes. Prices change. Rules change. Revenue changes. Our health may change. Until several years pass, we will have no idea what we will be dealing with.
For that matter, we don't know if we will be in a truck at all. We have lived a great life on the road and made some really good money as expediters, but if the CARB rules end up taking the good money and fun out of the business, we are out too. Expediting is not a charitable activity. We do not haul freight to break even or suffer losses. If the money is not there, neither are we.
We always figured that we would replace the reefer once over the life of the truck. The replacement would come before 2012, when the reefer would run afoul of the CARB rules. Putting a CARB-compliant reefer engine in now and having the government pay for 75% of it is an attractive option that will extend the life of the reefer.
Hanging that DPF monstrosity on the truck is not an attractive option, even with the government paying 100% of the cost (assuming we get the grant). We do not know how fuel economy will be affected, or if it will be affected at all. The DPF regeneration produces exhaust temperatures of 1,100 degrees F. That may require some custom exhaust work to keep that heat away from the underbody reefer. It adds weight to the truck (thank goodness we spec'ed a 14,600 lbs front axle when we built the truck). It adds maintenance costs that we do not now have to pay.
The only advantage is the DPF extends the useful life of the truck under the CARB rules. With the possibility of having the governemnt pick up 100% of the $35,000-$40,000 cost today, the above disadvantages are offset. Of course, there is also the public benefit of cleaner air that benefits one and all.
The crazy part of this is you can replace an entire truck engine for less than $40,000. Thanks to CARB rules and stimulus money, we now have tax dollars used to spend $35,000-$40,000 a pop to hang ungainly exhaust system components on a limited number of trucks.
When we bought our truck, we planned to run it for ten years or more and hoped agressive maintenance would enable us to do so without an engine rebuild or replacement. But we also allowed for the fact that the engine might have to be replaced at some point.
Without the grant money, we would probably run the truck as long as possible and then make a decision when crunch time came. Options would then include replacing the entire truck, replacing the engine and exhaust system with one that is CARB-compliant, or modifying the existing exhaust system to be CARB-compliant.
With several years between now and then, and with any number of things likely to change (rules, revenue, technology, prices, etc.), and any number of things that may happen (unexpected blown engine, lucrative inra-state opportunity that prompts a switch to dry box truck, easier money made outside of trucking, etc.) there is no way to plan anything. We can only do our best to know what is going on and prepare for as many possibilities as we can forsee.
Today, our single best action is to apply for the grant money, which we are in the process of doing. We cannot know what to do next until we know if the money is granted or denied.
