If your diesel powered RV motorhome coach is stranded on the roadside with a no start or severely insufficient power prognosis, the problem may stem from some degree of a failure of or degradation of the fuel delivery system. Driver observable symptoms of such a condition can be one or more of the following:

  • Foul odor sourced at the fuel tank
  • Dark or clouded fuel
  • Debris floating in the fuel tanks
  • Clogged or slimy fuel filters
  • Recent history of shorter filter life
  • Noticeably excessive exhaust smoke
  • Increased fuel consumption
  • Loss of power and/or RPMs in ratio to fuel pedal travel
  • Poor starting
  • Poor idle
  • Noise

Fuel pump failure or corroded, pitted and sticking fuel injectors can also be symptoms; however, these would usually not be conditions that are easily observable by most drivers.

If your RV is stopped in its tracks and you have observed any of the above symptoms, RV Repair New Mexico’s Mobile Roadside Repair can assist you to get your fuel delivery system humming again.

Fuel Injectors

Many OEM’s dictate as part of their warranty and maintenance programs the mandatory replacement of fuel injectors at an engine’s hours of operation half life. Why is this? If an engine is fueled throughout it’s life span with diesel fuel that is specified at OEM fuel cleanliness levels, the fuel injectors should last the life of the engine, right? Not so.

Diesel Fuel

As the delivery sector of U.S. consumer goods proceeds in monthly and yearly work schedules with their consequential and perpetual mileage accumulations , the quality of the diesel fuel powering these delivery fleets can come to be taken for granted. If the fuel is purchased at reputable outlets or dispensed from company tanks, that fuel is top quality, right? Not so.

There are several factors that can contribute to diesel fuel being dispensed into diesel powered RV recreational vehicles that technically is a fuel that is of a quality lower than that which is specified by OEMs. This occurrence is not intentional, but it does happen regularly.

Diesel fuel is inherently unstable. Diesel engines run optimally on fuel that is “fluid”, or pliable liquid in nature. Because diesel fuel is unstable, solids continually form and in turn these lead to a growing accumulation of sludge deposits within fuel tanks, lines, fuel filters and injectors.

The solids that accumulate are formed in the process of the fuel’s natural degradation as it is subjected to organic, elemental reactive factors and the heat and pressures imposed upon it from the engine’s fuel delivery and burning system. These solids form as a bio-film throughout the system and as asphaltenes (high carbon molecule content) that are left over in the surplus, unburned fuel that is delivered from the engine’s combustion process back to the tanks.

Co-Contributor Contamination Puzzle

The list below presents an array of factors that work together as co-contributing players, all exhorting one force or another upon diesel fuel. It is a completely natural and expected process of assault brought to bear on the quality of the fuel. Like a puzzle, one would not recognize that one part is actually joined with other parts unless the puzzle were completed; or in the case of puzzles, one had the picture on the puzzle box to look at.

Fuel Shelf Life – Diesel naturally degrades over time
Oxidation – Degradation in stability status through loss of electrons
Fuel Cleanliness – Fuel degrades during delivery time from refinery to RV consumption
Bio-Film – Micro organisms, enzymes, bacteria, yeast, mold and fungi
Bio-Diesel Blends – Further contributes to instability of fuel, thus increasing water & microbials
Biocide Additive – Can exacerbate bio-film transition into system clogging solids
Asphaltenes – Unburned fuels transformed into low combustible solids
Water – Provides environment in which bio organisms can multiply
Ultra Low Sulfur – Sulfur is anti microbial and anti fungal. Less sulfur equals more… you guessed it.

Here is a picture of these forces working together in the degradation of diesel fuel. A long fuel shelf life will contribute to the accumulation of waters in the fuel which can increase the likelihood of bio-films advancing and accumulating. Add to the picture Bio-diesel blends with the ultra low sulfur diesels now mandated by government stipulations and we have a snowballing effect. Fuel degradation only increases. The fuel becomes more unstable.

The ending result is its effect upon engine fuel systems. As goes the fuel, so goes the fuel systems. Degradation has its pay out in more frequent maintenance schedules and shorter engine component life spans. Over time the end result is the decrease of engine efficiencies and, unfortunately, the degradation of the bottom line and that’s where it can be felt the most.

Three Fuel Injector Points Of Degradation

Each of the three points, listed below, in today’s fuel injectors are adversely affected by the abrasive and erosive affects of contaminations in diesel.

  1. Injector nozzle holes, the blockage and erosion thereof and its impact on spray patterns.
  2. Injector needle valves, the erosion thereof and its impact on sealing off fuel, the resultant dripping of fuel into the cylinder and excessive piston crown temperatures causing crown deformity and engine failure.
  3. Injector control valves, the erosion of the injector valve seat’s sealing surfaces, restriction of pintle movement, slowed valve movement and its impact on injection timing.

Fuel injector degradation will eventually lead to partial, functional failure and can lead to catastrophic failure.
