SERIES 60 FUEL

The quality of fuel used is a very important factor in obtaining satisfactory engine performance, long engine life, and acceptable exhaust emission levels. The Series 60 engine was designed to operate on most diesel fuels marketed today. In general, fuels meeting the properties of ASTM Designation D 975 (Grades 1D and 2D) have provided satisfactory performance. The ASTM D 975 specification, however, does not in itself adequately define the fuel characteristics necessary to assure fuel quality. The properties listed in Table , Diesel Fuel Specification Table, provide optimum engine performance. ‪

Diesel Fuel Specifications







Fuel Lubricity

Fuels such as those containing kerosene and jet fuel and some low sulfur fuels have characteristics which may cause operational concerns in some engine designs. The fuel injection systems used on VM and natural gas Detroit Diesel manufactured engines has demonstrated trouble-free operation on a wide variety of fuels without the need for supplemental additives. ‪

Biodiesel Fuels

Biodiesel fuels may be produced from a wide variety of sources and may be used in all DDC engines provided (1) they are derived from soy methyl ester (SME) and/or rape methyl ester (RME) and (2) are blended to a maximum of 20% by volume in diesel fuel. The resulting blend must meet the properties listed in Table . ‪

Although such blends purport to reduce exhaust emission particulates, they increase the nitrogen oxides in engine exhaust. They also tend to have poorer thermal stability and may deteriorate engine oil TBN more rapidly than wholly petroleum-based diesel fuels. These fuel blends have not been fully evaluated relative to diesel fuel system durability or engine oil effects. ‪

Other Fuels

In addition to the diesel fuels listed in Table , customers have used other fuels successfully, including fuels marketed as premium diesel fuels, kerosene-based jet fuels, and other fuels listed in Table . These fuels have provided economic and availability advantages for some applications, particularly where 1-D type fuels are required, and may be used in all Detroit Diesel engines. These fuels should be accompanied by exhaust emission data demonstrating emission equivalency to 1-D for those engines requiring 1-D fuel. Fuel type specifications and applications are listed in Table . ‪

Fuel Type Specifications and Applications

Lower density fuels, such as those listed in Table 5-2 and "winter blended" diesel fuels, have a lower volumetric heat content than the standard 2-D fuel listed in Table . Operating with these fuels will result in reduced engine output and reduced fuel mileage, compared to standard 2-D fuel. Reductions of 5% are not unusual and may be as high as 10%. A good rule of thumb is: The engine power is proportional to the heating value of the fuel. ‪

Lower density fuels also tend to have lower viscosity and poor lubrication characteristics. ‪

Fuel Cleanliness

Fuel should be clean and free of contamination. Storage tanks and stored fuel should be inspected regularly for dirt, water, or water-emulsion sludge, and cleaned if contaminated. Storage instability of the fuel can lead to the formation of varnish or sludge in the tank. The presence of these contaminants from storage instability must be resolved with the fuel supplier. If fuel is stored on site, the following is recommended: ‪

NOTICE:

Do not use a fuel storage tank or lines made from galvanized steel. The fuel will react chemically with the galvanized coating to form powdery flakes that will quickly clog fuel filters and cause damage to the fuel pump and injectors. ‪

  1. Keep the storage tank filler cap covered to prevent contamination by rain water.
  2. Keep the tank clean, especially around the filler cap and tap areas.
  3. Position the tank so that it tilts slightly toward the bottom drain. This will make it easier to drain accumulated water and sediment.
  4. Minimize condensation by keeping the tank reasonably filled at all times.
  5. After filling the fuel storage tank, wait a few hours before filling equipment tanks. This will allow contaminants to settle.

Cold Weather Operation

In cold weather, diesel fuel will form wax crystals that can restrict flow and clog filters. Fuel suppliers approach this problem several ways. Some provide a specially refined product, while others may use flow improving additives or winter blends. Winter blended fuel will likely contain kerosene or 1-D fuel, which provide good cloud point temperatures but will result in a lighter fuel with a lower heat content. The use of such fuels is acceptable but may result in reduced engine power and/or fuel mileage. ‪

Prohibited Fuel Additives

Used Lubricating Oil: Detroit Diesel specifically prohibits the use of drained lubricating oil in diesel fuel. Used lubricating oil contains combustion acids and particulate materials which erode injector components, resulting in loss of power and increased exhaust emissions. In addition, the use of drained lubricating oil will increase maintenance requirements due to filter plugging and combustion deposits. Refer to the section for recommendations on proper used oil disposal. ‪

FIRE

To avoid injury from fire, keep all potential ignition sources away from diesel fuel, including open flames, sparks, and electrical resistance heating elements. Do not smoke when refueling.

Note: Do not add gasoline to diesel fuel.

Besides creating a serious fire hazard, the presence of gasoline in diesel fuel will reduce fuel cetane number and increase combustion temperatures. Tanks which contain such mixtures should be drained and cleaned as soon as possible. ‪

Gasoline: The addition of gasoline to diesel fuel will create a serious fire hazard. The presence of gasoline in diesel fuel will reduce fuel cetane number and increase combustion temperatures. Tanks which contain such mixtures should be drained and cleaned as soon as possible. ‪

Waste Oil Disposal and Rerefined Oils

With over one billion gallons of waste oil generated annually in the U.S. alone, disposal of waste oil has become a serious environmental concern. Rerefining waste oils provides an environmentally viable way of handling this material. Detroit Diesel favors the recycling of waste oil and permits the use of rerefined oils in all engine product lines, provided the rerefined oil meets the SAE Viscosity and API specifications previously mentioned. ‪

FIRE

To avoid injury from combustion of heated lubricating-oil vapors, stop the engine immediately if an oil leak is detected.

FIRE

To avoid injury from fire, do not smoke or allow open flames when working on an operating engine.

FIRE

To avoid injury from fire from a buildup of volatile vapors, keep the engine area well ventilated during operation.

Consideration for the disposal of waste oil should begin when negotiating the purchase of new oil. Oil supplier selection criteria should include a proposal for handling waste oil. It is important to know exactly how the oil will be disposed of since it is the generator, not the hauler, that is ultimately responsible for its proper disposal.
