2.3.13. Fuel filter z The filter cartridge should be replaced at every 40,000 km (500Hr). Fuel filter and cartridge 2.3.14. Fuel requirements z DOOSAN diesel engines was designed to use Number 2-D diesel fuel or equivalent that meets specification ASTM D (Grade Low Sulfur) . For maximum fuel economy, Number 2-D fuel whenever possible. When temperatures are below -7 ° C, use Number 1-D fuel. If Number 1-D fuel is not available, the mixture of one kerosene to two gallons of Number 2-D fuel can be used. Once kerosene has been added, the engine should be run for several minutes to mix the fuel. 2.3.15.
How to select fuel oil z Fuel quality is an important factor in obtaining satisfactory engine performance, long engine life, and acceptable exhaust emission levels. DOOSAN engines are designed to operate on most diesel fuels marketed today. In low sulfur, fuels meeting the properties of ASTM Designation D975 (grades 1-D and 2-D : Grade Low Sulfur) have provided satisfactory performance. z The ASTM 975 specification, however, does not in itself adequately define the fuel characteristics needed for assurance of fuel quality. z The properties listed in the fuel oil selection chart below have provided optimum engine performance. Grade 2-D fuel is normally available for generator service.
Grade 1-D fuel should not be used in pleasure craft engines, except in an emergency. DL06 Diesel Engine Technical Information 27
