The tunnel mucking loader needs a diesel engine to provide sufficient energy and power to work efficiently, but sometimes the diesel exhaust will emit black smoke. Why?
1. The exhaust pipe emits black smoke, and there is a flame inside the muffler, and the sound is dull. This phenomenon occurs because the oil supply time is too late. The oil supply time is too late, often causing the diesel engine to overheat, the exhaust temperature rises, and may even burn out the machine parts.
2, the tunnel mucking loader supercharger is faulty, causing insufficient supply pressure, so that the diesel engine is not completely burned, the supercharger should be overhauled.
3. If the injector is poorly atomized or has oil dripping, the injector should be checked and repaired. If necessary, replace the injector (needle valve coupler).
4, the tunnel mucking loader oil supply is uneven. The exhaust pipe emits black smoke, and the machine vibrates severely, supplying too much oil to individual cylinders.
5. Diesel quality is poor. The quality of the diesel oil is poor, causing poor atomization, so that it cannot be completely burned. The fuel tank should be cleaned and the diesel oil replaced.
6. The exhaust pipe emits black smoke, and the cylinder is accompanied by a crisp knocking sound, which is rude. This phenomenon is usually caused by the premature oil supply time. The oil supply time is too early and usually causes difficulty in starting.
In short, when the diesel engine of the tunnel mucking loader is overloaded, suddenly accelerated, climbed, or under heavy load, it is normal to exhaust black smoke. However, when black smoke or heavy load is used under heavy load or small load, it is an abnormal phenomenon, so it is necessary to pay special attention.
