Chapter2 Operation of Diesel Engine
In order to guarantee the reliability of supply system, the clean diesel produced by regular oil company
in the country and in conformity with the state
’
s standard must be used; in case of automatic filing, the
fuel vessel must be clean and used exclusively; the fuel filling shall be tried to be carried out in sealing;
the diesel to be filled must be precipitated for more than 48 hours and that in the upper part of the
vessel shall be used.
The selected diesel brand is related to ambient temperature. When the temperature is low, the wax in
the diesel is separated resulting in increased viscosity and blocking the pipeline, which will cause
difficult startup and black smoke. On the contrary, if the diesel for winter is used in summer, high
temperature will result in decreased viscosity causing bad lubrication in supply system, which may
damage injection pump and injector; moreover, lead to delayed ignition causing short of power and
white smoke. Therefore, different brands of diesel shall be used in different seasons and at different
regions.
Please use diesel as the requirement in the following table based on local climate conditions.
