●
Apply the following grades of diesel fuel based on the ambient
temperature.
If the ambient temperature is higher than 5
℃
, it is recommended to use the
0# diesel fuel (GB 252-94) .
At low temperature, the diesel fuel may precipitate the waxy material,
leading to poor mobility of diesel fuel. In such case, the fuel system will be
clogged, causing failure of diesel engine. Therefore, if the ambient
temperature is less than 0
℃
, please use the diesel fuel suitable for winter.
According to the GB252 diesel fuel standard, if the ambient temperature is
－
5
℃
or more, please choose the
－
10# diesel fuel. If the ambient
temperature is
－
14
℃
or more, please choose the
－
20# diesel fuel. If the
ambient temperature is
－
29
℃
or more, please choose the
－
35# diesel fuel.
If the ambient temperature is
－
44
℃
or more, please choose the
－
50# diesel
fuel.
1.3 Coolant
1.3.1 Coolant must be filled in the cooling system of diesel engine
The coolant for the industrial power engine, which is glycol type, should have the
features like antifreezing, anticorrosion and scale proofing, as well as high boiling
point.
