Diesel Generator Oil Change Guide

Many users encounter the problem of not knowing how to add and replace oil for diesel generator sets after purchasing and installing them, and they don't know the correct operation steps for changing the oil of diesel generators. In this regard, Dingbo Diesel Generator Manufacturer introduces in detail the problem of changing the oil of diesel generators.

Understand Oil Grades and Clarify the Role and Grades of Oil

At present, the viscosity grades of oil are specified with names such as SAE, and OW, 5W, 10W, 15W, 20W, 25W indicate the viscosity level of oil at relative temperatures in cold regions. The smaller the number, the better the temperature resistance. SAE20, 30, 40, 50 are viscosity grades, and the larger the number, the higher the viscosity. The evaluation standard for fuel quality grade is referred to as API for short. The grade of gasoline engine fuel starts with S, and the later the letter, the higher the grade, including SA, SB, SC, SD, SE, SF, SG, SH, SJ, etc.

Diesel engine fuel starts with C, including CA, CB, CC, CD, CE, CF, CG, etc. Different brands of diesel engines add different grades of oil, which can be added according to the actual situation.

The Specific Operation Steps for Changing the Oil of Diesel Generator Set Are as Follows

1. Place the generator set on a flat surface and start the engine for a few minutes to increase its oil temperature, then stop the engine.

2. Remove the oil filler bolt; when removing the oil drain screw, place an oil basin under the engine, and the oil can be drained from the crankshaft oil tank.

3. Check the sealing ring, rubber ring and oil screw, and replace if damaged.

4. Reinstall the oil drain screw and tighten it; add oil to the upper position of the mesh grid of the oil dipstick.

After Changing the Oil of the Diesel Generator Set, the Oil Mainly Plays the Following Roles

1) Lubricating effect: If the engine is running without adding oil, dry friction will occur, which will not only cause damage to the parts but also generate frictional resistance. Oil is to lubricate all parts.

2) Sealing effect: Because there are gaps between parts, oil can form an effective seal between the gaps to prevent gas leakage and the intrusion of external pollutants.

3) Cooling effect: When the engine is running, friction between parts will generate heat, and oil can cool the parts and reduce the temperature of the engine.

4) Cleaning effect: During engine operation, iron filings, impurities and unburned substances generated by friction can be taken away by oil, avoiding the formation of sludge on the surface of parts and keeping the surface of parts clean.

5) Anti-corrosion effect: During engine operation, not only friction will occur, but also rust will occur. Oil can reduce the chance of parts contact and wear and avoid rust.
