clogging of fuel fitters by crystals.
4.8.6 Fuel requirements
KOEL Diesel engines was designed to use Number 2-D diesel fuel or equivalent that meets specification
DIN 51601-DK. For maximum fuel economy, Number 2-D fuel whenever possible. When temperatures are
below -7’C(20°F), 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.
4.8.7 How to select fuel oil
Fuel quality is an important factor in obtaining satisfactory engine performance, long engine life, and
acceptable exhaust emission levels. KOEL engines are designed to operate on most diesel fuels marketed
today. In general, fuels meeting the properties of ASTM Designation D975 (grades 1-D and 2-D) have
provided satisfactory performance. The ASTM 975 specification, however, does not in itself adequately
define the fuel characteristics needed for assurance of fuel quality.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.
