Ask Professor Diesel – 05/26/2014

 

This week’s question comes from John in the USA:

 

Professor Diesel:

I know that diesel engines can run on many types of fuel, what would happen if I try and use gasoline?

 

Answer:

NEVER use gasoline in a diesel engine. At best, permanent damage will result. At worst, explosion or fire. Some diesel operators will add a little gasoline to diesel when preparing for storage over extended periods, as this can help in starting (MarineDiesel does not recommend this practice and it will void your warranty if you try it). NEVER more than 10% of total volume. The engine will run, but it is safest to drain the fuel and lines if gasoline has been added.

Maintenance Tip of the Week – Exhaust 05/26/2014

 

Maintenance Tip of the Week

05/26/2014

Always check the exhaust system for dents and blockages. Restricted air flow in the exhaust system can trigger fault codes or seriously hamper performance.

Maintenance Tip of the Week – Gaskets 05/19/2014

 

Maintenance Tip of the Week

05/19/2014

Always use gaskets of the proper thickness. Though it can be tempting to try and save money by using aftermarket parts, MarineDiesel uses gaskets of very specific thickness and quality to prevent leakage and give a long engine life.

This week’s question comes from Marten in the Netherlands:

 

Professor Diesel:

I have two VGT engines mounted in a boat that has been sitting in a shed for over one year. What should I do to prevent damage the next time I use the boat.

 

Answer:

Diesel engines can incur a lot of damage when they sit idle for long periods of time. Ideally, you should start engines at minimum, once per month, or follow the extended storage procedure documented in your manual. Oil collects in the crankcase and becomes sludge, water condensation forms in fuel tanks and fuel lines, dust can get into various parts of the engine, and corrosion can start and get worse if the engine is not periodically inspected. Diesel fuel also quickly degrades over time. Assuming that the manual storage procedures were not followed, what should you do?

 

  1. Drain all fuel from the lines and tank, oil from the engine, and any fluid remaining in the water intakes.
  2. Inspect all hoses, connections, and fuel lines.
  3. Inspect the belts.
  4. If sludge has developed in the engine or crankcase, it must be removed.
  5. The fuel injectors must be checked and replaced if necessary.
  6. Change oil, fuel, and air filters.
  7. Clean the supercharger.
  8. Add water repellent to the fuel.
  9. Clean and flush the cooling system.
  10. Replace the impeller.
  11. Make certain that the batteries are fully charged and that connections are tight and corrosion free.
  12. Use the startup procedure described in your manual, just like with a new engine.

 

All of the above procedures must be done in accordance with the manual. If excessive sludge has built up, a rebuild or complete overhaul may be necessary.

Use your senses

 

 

Your engine talks to you. It’s true, really. When you first step aboard and hit the start button, your engine is telling you how it is performing. The MarineDiesel panel is only verification of what your senses tell you.

Look: Look for leaks. Frequently. Drips or pools of oil, coolant, or fuel are never a good sign. Look for smoke, every time the engine starts. Look at your gauges for excessive fuel or oil consumption.

Listen: Listen for abnormal noises. Something doesn’t sound right? Then there is a problem. Sure, it may be minor, but minor problems have a way of becoming major problems. Knocking, pinging, humming, or simply just too loud.

Feel: Vibration. Though there is always a certain amount of vibration present, strong vibration or intermittent vibration can indicate a serious problem. Note that hull materiasl can amplify vibration significantly.

Smell: Odors of fuel, “burning”, smoke, or other unusual smells always are good indicators of problems.

Your senses are the first indicator of mechanical problems. Of course, on MarineDiesel electronic engines, we provide you with a sophisticated ECU and diagnostics package. All problems can be solved. We give you the tools to solve them quickly, and at least cost, if you only use your senses and do not ignore the warning signs.

Maintenance Tip of the Week – Oil Filters 05/12/2014

 

Maintenance Tip of the Week

When changing oil filters, before mounting the filter, fill the oil filter completely with oil. This ensures that the engine is completely lubricated directly from startup.

Ask Professor Diesel 05/12/2014 – Kerosene

This week’s question comes from Mark in the USA:

 

Professor Diesel:

In my area, kerosene is considerably cheaper than diesel. Will my MarineDiesel engines run on kerosene without being damaged?

Answer:

Kerosene is sometimes used to thin diesel to help prevent gelling in cold weather, but it also reduces the fuel’s lubricity as well.

Diesel engines are highly tolerant of different types of fuel formulations and can run on just about any oil-based fuel, but that doesn’t mean they should or that there is any benefit in doing so. Diesel engines are more or less indifferent to fuel types, but the emissions and injection controls on MD engines could possibly be damaged by using any fuel other than recommended in your model’s manual. Additionally, this means that you risk your warranty and performance levels would suffer, as the engine’s ECU is programmed at the factory based on fuel type, to optimize your performance. Since emissions levels produced by the engine are also based on a specific fuel use,  you could also find yourself violating local laws regarding air quality.

For illustration purposes only, the following is a  list of fuels that generally can be burned in a diesel engine (Though “can be burned” does NOT necessarily mean “should be burned”):

  • Diesel #1
  • Diesel #2
  • Diesel #4
  • ULSD (Ultra Low Sulfur Diesel)
  • Biodiesel (from B5 to B100)
  • Kerosene
  • Home heating oil
  • Civil jet fuel (Jet A-1, Jet A, Jet B)
  • Military jet fuel(JP-4,JP-5,JP-8)
  • SVO (Straight Vegetable OIL)
