I am just lucky I guess. My wife drives 60 mile a day to work.
It seems I really need to educate myself more about modern diesels...have no idea what regen is or what any of those other letters mean! Or maybe I'll just go with the HEMI.
NOW...how can I raise$ 50,000????
Deciphering the diesel alphabet soup:
DPF: Diesel Particulate Filter. A filter installed in the exhaust system that trap carbon particles from fuel combustion. When the filter becomes obstructed, this is detected by the engine's computer and a cleaning cycle called a "regeneration" is initiated. Extra fuel is introduced into the exhaust stream by an additional injector or extra fuel is provided by the engine's injectors creating a hotter than Haides internal temp. in the filter to burn off the soot. How a truck equipped with DPF is driven may affect the frequency of regeneration.
SCR: Selective Catalyst Reduction: This is another exhaust 'scrubber' in which Diesel Exhaust Fluid (urea) is introduced into 'vessel' that looks something like a catalytic converter in the exhaust system. The DEF reacts with the hot exhaust and catalyst contained within the vessel, to reduce oxides of nitrogen in the treated exhaust. An SCR equipped vehicle has a reservoir that has to be filled with DEF, and generally holds enough DEF to typically lasts 5000 miles or more. Run out of DEF, and the computer will place the engine in a 'limp' mode. DEF can be purchased at auto parts store, Wally World, or in bulk from a pump at many truck stops.
