In addition to the daily use and maintenance of engine oil, but also many koretomo neglected problems at work, if the oil temperature and pressure is abnormal, the engine will appear a variety of problems, even the strike.

If the oil temperature exceeds 120 degrees C for a long time, it will lose its lubrication, cleaning and heat dissipation, which will cause the engine to burn the shaft when it is serious.

Here, we have collected 10 main reasons for the high temperature of oil, let's have a look.

1. insufficient or excessive oil

Replace the oil when many drivers feel better is easy to make mistakes, too much oil will produce greater resistance to the engine, and a shortage of oil and influence of lubrication and cooling, so the oil change, we should be in strict accordance with the scale of oil scale for processing, not too much and too little.

2. oil pump failure

Usually, the dashboard of the vehicle are integrated alarm device of low oil pressure at work, if found dashboard corresponding fault indicator lights up, the oil pump failure, should immediately seek professional maintenance personnel to repair.

In addition to the oil itself, the oil pump is also a cause of abnormal oil pressure.

3. cooling water temperature is too high

If the temperature of the water cooling system in the engine is too high, the engine parts can not be cooled in time and the heat is taken away in Baotou, then the heating parts will indirectly lead to the rise of the oil temperature.

Therefore, regular inspection of the engine cooling system pumps, oil cooler and other important components, to ensure that the engine itself cooling system work properly.

4. oil cooler is blocked

If the oil cooler is blocked, it will directly affect the normal cooling of the oil, and will lead to insufficient oil pressure and other problems.

In the daily maintenance, should also regularly check the oil cooler, if found problems, should be promptly cleaned or replaced.

5. filter blocked

In the replacement of oil filter machine, should be replaced, if not long-term change, will directly lead to the filter is blocked, without impurities in the oil interception effect, the oil directly from the bypass valve to the engine, causing the internal wear.

6. piston ring seal is lax

If Baotou beiben heavy truck engine parts of piston ring seal, can also cause the oil temperature is too high, when the cylinder leaks air, cause the crankcase ventilation is too large, the oil out of the engine with external ventilation, so regularly check the sealing of the engine piston ring and cylinder seal is also very important.

7., the bearing clearance is too big

Bearing gap is too large, too much oil leakage, leading to too low oil pressure, can not form a normal oil film, but lighter wear degree, heavy strain, ablation, friction surface.

8. heavy duty work of engine

Engine heavy load work, that is, overload state, will lead to oil temperature rise, after all, the greater the pressure, the heat emitted by the engine will be higher.

When the engine oil can not meet the need of the engine in time, the temperature will also rise rapidly, so we should try to avoid the engine working under overload condition for a long time.

9. engine assembly too tight

The same with other mechanical systems, when the engine internal mechanical parts assembly is tight, will lead to friction straight up, and have a very high heat, so that heat load oil received increases beyond the original heat load coefficient.

If the new car or overhaul the engine, this problem usually needs to run for a period of time can be solved, if after running in no change, should be timely return to factory maintenance.

10. poor quality oil

If you use the engine does not match the oil, as well as poor oil, will also increase the internal friction coefficient of the engine, so that the temperature is more obvious, while leading to rising oil temperature.

Therefore, in daily use, in addition to we need to choose the engine and engine oil level and viscosity, but also through formal channels for the purchase of Baotou North Ben heavy truck parts.
