The Phenomenon of Blocked Exhaust Pipes in Diesel Generator Sets

Blocking the exhaust pipe of a diesel generator set is a common fault. If the exhaust pipe is blocked, the unit will shut down after starting. If the engine is shut down and then forcibly refueled after starting, it will also cause carbon buildup and blockage on the piston in the cylinder. Long term attempts to start will damage the cylinder head and crankshaft of the diesel generator set, and if it catches fire, it will also have an impact on the diesel generator.

How to determine if the exhaust pipe of a diesel generator set is blocked? Generally speaking, if the exhaust pipe of a diesel generator set is blocked during operation, some fault phenomena will occur. When users discover these phenomena during normal use, they should consider whether the exhaust pipe is blocked.

1. The generator set is unable to load properly

If the diesel generator fault is ruled out, then we should consider whether the exhaust pipe is blocked, because the poor exhaust results in a decrease in intake volume and a decrease in diesel generator power.

2. There is a slight backfire phenomenon when refueling the diesel generator urgently

When the exhaust of a diesel generator is not smooth, some of the exhaust gas will remain in the cylinder, causing the mixture to become lean and the combustion speed to slow down. When the intake valve is opened, the mixture is still burning, so the burned mixture will backflow into the intake pipe through the opened intake valve, resulting in backfire phenomenon.

3. When the diesel generator accelerates or decelerates rapidly, you will hear the sound of the exhaust pipe rustling. This is usually caused by a damaged three-way valve leading to a blocked exhaust pipe.

4. The diesel generator injects fuel and ignites, but it does not start, which is often a symptom of completely clogged exhaust.

The blockage of the exhaust pipe of a diesel generator set can cause the unit to malfunction and affect the normal electricity consumption of users. When such faults are discovered, timely inspection and handling should be carried out. The above is the introduction of Dingbo Power on the blockage of the exhaust pipe of a diesel generator set.
