The engine of Yuchai diesel generator set is a high-pressure injection electronic control engine with high precision of parts, so the selection of engine oil is also very demanding. It is generally recommended to use engine oil above CF level. Diesel generator set oil can be very good. It plays a good role in lubrication, heat dissipation, cleaning, sealing, corrosion prevention, rust prevention, etc. When choosing oil, choose the appropriate brand of oil according to the local season and temperature.
Yuchai engines require the use of multi-grade oils, because multi-grade oils are suitable for a relatively large temperature working range, so that the oil viscosity can satisfy the normal engine in areas with large temperature differences between morning and night, as well as in a longer season. The need for work. Under normal circumstances, a new engine needs to be replaced after 50 hours of operation for the first time and 50 hours after a medium or overhaul. The oil replacement cycle is generally carried out at the same time as the oil filter (filter element), and the general oil replacement cycle is 250 hours or one month.
How to change the oil?
1. Place the Yuchai diesel generator set on a flat surface and start the engine for a few minutes to bring the oil temperature to a certain level, and then stop the engine.
2. Remove the oil filling bolt (that is, the oil dipstick).
3. Place an oil pan under the engine, remove the oil drain screw, and let the oil drain from the crankshaft oil tank.
4. Check the oil drain screw, sealing ring and rubber ring, if damaged, please replace it immediately.
5. Reinstall and tighten the oil screw.
6. Add oil to the upper position of the oil gauge grid.
In addition to the regular oil replacement, when the oil has deteriorated due to impurities or moisture, it needs to be replaced. If you want to accurately determine the oil replacement time of Yuchai diesel generator sets, the user can understand that there are two ways to determine the oil replacement:
1. Use two glass test tubes with a diameter of 0.5 cm and a length of 20 cm, respectively, into 19 cm of new engine oil and used engine oil. After sealing, the two tubes are turned upside down at the same time, and the time of bubble rise is recorded. If the difference between the two is more than 20 %, it means that the viscosity of the used oil has dropped too much and should be replaced.
2. Compare the new engine oil and the used engine oil with one drop each on the white filter paper. If there are more black spots in the used oil drop, it indicates that the engine oil has not deteriorated and should not be replaced, if the engine oil is dark brown, then in order to deteriorate, it should be replaced.
