1. Must use a suitable quality oil quality, which is the key to ensure the normal operation of the engine.
2. Temporarily adopt alternative oil products to enhance observation. If oil supply is not timely or there is no suitable oil product, the substitute oil product can be used temporarily. However, observation must be strengthened during use. Pay attention to the quality of the oil product and whether the oil filter is clogged. Situation, found problems with timely parking treatment.
3. The oil with the proper viscosity should be selected according to the local temperature and the oil with the right viscosity should be selected. The view that the bigger the viscosity is better is wrong, because the viscosity is too high, the oil flow is too slow at the start, and it is easy to make the wear of the parts more serious. It even caused a tile burning accident.
4. When draining the oil, drain the waste oil to prolong the service life of the engine. When replacing the oil, the old oil must be completely drained to avoid contaminating the newly added oil, causing the new oil to deteriorate rapidly and causing corrosive engine wear. Under normal circumstances, put the waste engine oil at high temperature, and then add washing oil (85% of common motor oil and 15% of gasoline are mixed). After starting, it is idling for 10 minutes, then released, and finally cleansed again. Oil can be.
5. Keep the crankcase well-ventilated The gas that enters the crankcase from the combustion chamber is corrosive, which can oxidize and deteriorate the engine oil and contaminate the engine. Therefore, the crankcase must be well ventilated.
6. Maintaining a normal oil level When the oil level is insufficient, not only will the engine oil be spoiled, but the machine parts will be burned due to lack of oil. Conversely, if there is too much oil, the oil will be along the cylinder wall and between the piston rings. The gap broke into the combustion chamber, causing the engine to burn oil. In addition, the oil level is too high, which increases the agitation resistance of the oil and increases the fuel consumption and wear.
7. Regularly maintain the oil filter regularly check and maintain the oil filter, replace the filter element in time, the driver should be aware of.
8. Regularly or qualitatively change the oil quality of any oil, after using a certain mileage, some physical and chemical indicators change, will cause damage to the engine, resulting in failure, so according to the oil changes regularly according to the quality of oil change.
9. When using thickened engine oil, the oil pressure is slightly lower than that of the same grade of general engine oil. Because thickened oils have good viscosity and viscosity, they have a higher viscosity at high temperatures and a lower viscosity at low temperatures. The viscosity is slightly lower in the normal engine temperature range, so a lower pressure is normal.
10. When using all-year general-purpose engine oil or thickener engine oil in winter, do not add ordinary engine oil to avoid affecting low-temperature startability. Add ordinary motor oil gradually in the spring or when changing to general engine oil.
Scientific life: how to do well in disease prevention during continuous drought?
Recently, the number of outpatients in various medical institutions in Beijing has surged, the number of patients with cardiovascular and cerebrovascular diseases and respiratory diseases has increased, and the beds in some hospital wards are very tight. Experts believe that this is related to the continuous drought.
Although a few days ago, an artificial precipitation ended the 110 day dry weather in Beijing, the air relative humidity in Beijing is still significantly low. The minimum air relative humidity measured by the meteorological department is less than 20%, and the daily air relative humidity is no more than 50%. According to scientific research, the relative humidity of the air comfortable to the human body is 60% to 70%. Exposure to a dry environment for a long time will have many adverse effects on human health.
Recently, during an interview with several major hospitals in Beijing, the reporter found that the number of outpatients and inpatients in hospitals increased sharply. According to experts, affected by abnormal weather, more patients came to the hospital before and after the spring festival than in the same period in previous years, which is related to the activity of bacteria and viruses and the impact of human physiological activities under warm and dry weather conditions.
Experts suggest that in a dry environment, aroma diffsuer can be used to alleviate air drying and moisturize the skin to a certain extent
