Precautions for preheating of excavator engine

1, both the EFI diesel engine and the direct injection diesel engine need preheating.

Because the purpose of engine warming is not only to make the fuel burn fully, but also to increase the temperature of the antifreeze, it also has the function of forming lubricant film.

2, the engine warm-up time is not as long as possible.

If a long time is, then the diesel engine made useless, it is not only a waste of fuel and is not conducive to environmental protection. Generally, it is more suitable to preheat 3-5 minutes before the diesel engine starts to load.

3, as many times as possible under the refrigerator to start.

The diesel engine starts repeatedly, will aggravate the wear degree of the moving parts, and reduces the service life of the parts and the engine. According to the authoritative research shows that more than 50% of the engine wear is caused due to the cold start, cold start wear is due to lubricating oil did not reach the work performance, so to reduce the number of cold start will prolong the life of engine.

4, when the engine warm up, should check the engine related parts and operation is normal.

When the engine is warm, you should check the indicator light on the dashboard, and listen to the abnormal sound of the engine to see if the engine smoke is normal or not.

5, look at the tachometer to determine whether the idle speed is normal.

Under normal circumstances, the machine hand only need to see whether the tachometer is normal, you can determine whether the warm-up of the machine is completed. Because the machine thermal expansion did not reach consensus, so the automatic governor will believe that the larger engine load, speed will be high when the speed is normal, it means that the thermal expansion of the machine to reach consensus, at this time can be found to preheat the machine has been completed.

Summary: every winter, the engine warm-up has become a hot topic. In fact, according to experience, the engine preheating is not only in winter, but also needs preheating in summer, but the winter needs preheating for a long time, and the summer warm-up time is short. So here comes the question. Is your excavator warm up when it starts?
