How to deal with tractor exhaust pipe fire
Exhaust anomaly is a comprehensive reflection of internal engine faults. Therefore, whether the exhaust gas is normal or not is one of the important signs of judging the working condition of the engine. Timely processing can ensure the normal operation of the diesel engine and avoid unnecessary economic losses.
The fuel did not have time to fully burn, and did not even reach the peak of combustion. The engine went to the next stroke, and the still burning mixture was discharged. The reasons for this phenomenon and the elimination methods were as follows:
1. The injection advance angle is too small. The processing method is to advance the entire angle and replace the wearing parts.
2. Misalignment of valve timing or just gear mounting error. The treatment is correct in time.
3. Some fuel injectors are clogged, and the oil valve occasionally shows severe wear. The treatment is to replace worn parts.
4. The exhaust valve does not close tightly, the valve spring is too weak, the spring is broken, or the valve clearance is too small. The solution is to grind or replace the valve and adjust the valve clearance.
5. The injector needle valve is badly sealed and there is a drip phenomenon. The solution is to replace the needle valve.
6. Part of the valve rod bending, stuck. The treatment is to replace worn parts.
