What happens when the exhaust air of the tiller smokes from the filter?

When the diesel engine is under load, it runs unevenly, and the exhaust pipe emits black or white smoke.

The black smoke is generally due to excessive fuel injection, uneven fuel injection of each cylinder, premature fuel injection time, blockage of air filter, excessive wear of piston rings or corresponding gaps between openings, abnormal governor speed, improper adjustment of maximum oil limiting screws, etc. The white smoke is generally discharged because the fuel injection time is too late, the fuel injection of each sub-pump of the fuel injection pump is inconsistent, the injector is dripping with poor spray, and there is water or air inlet in the fuel system.

During diagnosis and elimination, the oil injection volume of each cylinder is checked by the single-cylinder oil cut-off method. If the inspection cylinder no longer emits black smoke and the operation of the diesel engine changes very little, the fuel injection nozzle or fuel injection pump of the cylinder should be overhauled if the fuel injection volume of the cylinder is too large. If the amount of fuel injected in each cylinder is large, it should be checked whether the engraving position of the governor adjusting the gear rod is correct and whether the flying weight is stuck.

When there is no abnormal finding in the above inspection, the injection time should be checked to see if it is inaccurate, and if necessary, it should be adjusted according to the regulations.

The white smoke is mostly discharged due to the poor spraying of the fuel so that the fuel cannot be burned and is discharged as white smoke. It can still be checked by the cylinder-by-cylinder oil cut-off method to find out the faulty injector and adjust its injection pressure. If the exhaust emits white smoke and the engine is weak and easy to overheat, it means that the fuel injection is too late, and the fuel injection should be adjusted on time.

1. Black smoke from the exhaust pipe

It shows that the engine mixture is too thick, resulting in insufficient combustion. When the air filter is too dirty, the spark plug is poor, the ignition coil is faulty, etc., it will cause the engine to emit black smoke.

2. White smoke from the exhaust pipe

Explain that the injector is poorly atomized or dripping oil makes part of the gasoline not burn; There is water in gasoline; The cylinder head and cylinder liner have cracks that are invisible to the naked eye, and the cylinder gasket is damaged so that water enters the cylinder; The temperature is too low. It can be solved by the following methods: cleaning or replacing the injector, adjusting the injection pressure; Remove moisture from the tank and oil circuit; Do not buy low-cost and low-quality oil; Replace the cylinder head gasket, cylinder liner, cylinder head.

3. Blue smoke from the exhaust pipe

It shows that the engine oil enters the combustion chamber to participate in combustion, the piston ring and the cylinder liner are not completely run-in, and the oil enters through the gap; The piston ring is bonded in the groove, and the cone surface of the piston ring is reversed, losing the effect of oil scraping; The piston rings are worn excessively, and the oil runs into the combustion chamber through the opening gap; The oil pan oil level is too high; The valves and tubes are worn out, and the clearance is too large. It can be solved by the following methods: the new car or overhauled locomotive must run in the engine according to the regulations, so that the parts can be meshed normally; Look at the assembly mark clearly and install the piston ring correctly; Replacement of qualified or oversized piston rings; Find out the reason for the increase in the oil pan oil level and release the excess oil from the oil pan; Reduction of oil in the filter pan; Replace the valve guide.

What happens when the exhaust air of the tiller smokes from the filter? Hello, pro 1, the temperature is not enough, due to the engine temperature is not enough, the fuel injected into the cylinder and the mixed gas formed by the air, part of it can not be burned, and the exhaust pipe emits white smoke. Therefore, after the locomotive starts, attention should be paid to the insulation of the water tank, and the middle throttle is used to run so that when the locomotive temperature reaches more than 50 degrees, the load is gradually increased.

2. There is water in the diesel oil, and there is water leakage in the diesel oil, which directly affects the normal combustion of the mixed gas and emits white smoke. At this time, the precipitated oil should be released, the stagnant water should be discharged, and the diesel fuel should be replaced if necessary. 3. If the exhaust pipe continues to emit white smoke, it may be that the cylinder head and cylinder gasket of individual cylinders are damaged and water is ingressive, so it should be removed for inspection and replaced with damaged cylinder heads and cylinder gaskets.

In addition, if the intake valve is not closed tightly, white smoke can also appear, which should be inspected and repaired.

Summary. What happens when the exhaust air of the tiller smokes from the filter? Hello dear, There may be two scenarios:

1: The air filter inhales combustibles, such as cigarette butts that are not extinguished, causing the filter to burn. Generally, domestic filter elements have no flame retardancy, and there are no strict requirements in national standards; Imported brands such as Aokede, etc., have good flame retardant properties.

2: The engine valve cannot be completely sealed, resulting in the cylinder combustion exhaust gas rushing into the air intake system. I hope my answer is helpful to you, and finally I wish you good health and a happy mood again!
