Engine exhaust pipe injection

There may be the following reasons: whether the PVC one-way valve is blocked, and the one-way valve blockage causes the exhaust pipe to produce oil. The exhaust gas sprayed by the engine check refueling cover is too large, and it is also possible that the piston ring leaks air, resulting in the exhaust pipe spraying oil. Excessive oil filling, resulting in excessive oil can only be discharged from the exhaust pipe.

The exhaust gas pipe is used to exhaust exhaust gas and oil vapor. In order to balance the pressure of the crankcase, the exhaust pipe appears. The oil exhaust gas coming out of the engine is separated from the oil and the exhaust gas in the oil-gas separator. Part of the exhaust gas enters the engine and burns again, and part of the oil will return to the oil sup along the oil pipe.

There are two reasons: the cylinder is blowing; the crankcase respirator is blocked. Check it accordingly. If the exhaust pipe of some vehicles is connected to the upper part, the valve oil seal should be considered.It is recommended to check it.

[Pacific Automobile Network] The engine exhaust pipe injection oil is likely to be due to the aging of the crankshaft ventilation valve, or the failure of the piston, cylinder liner, piston pin and piston ring, resulting in the loss of the original sealing effect, resulting in the phenomenon of oil injection. It is necessary to find the damaged location and then replace it. That's it.

The exhaust pipe suddenly sprays a large amount of engine oil

1. There are many reasons for the exhaust pipe to spray engine oil, such as: 1. The crankshaft ventilation valve (PVC) is aging, the oil-gas separation fails, 2. The piston crankshaft cylinder liner and piston ring have a large wear gap. , the oil scraping effect is poor and the sealing effect is lost, resulting in oil splashing. 3. The wear gap of the valve duct is too large, causing the oil to rush down to the combustion chamber to produce oil exhaust gas.

2. It is likely that the crankshaft ventilation valve is aging. It is recommended that users replace the crankshaft ventilation valve. Secondly, it may also be because the wear between the valve rod and the valve duct is relatively serious, resulting in an excessive gap, resulting in the situation of oil.

3. The exhaust pipe injection oil is caused by a problem with the ventilation system of the crankcase. The simplest troubleshooting method is to directly pull out the oil diper to see if there is oil, and spray it out from the insertion tube of the oil diper. If there is, it means that the PCV valve is broken. Because high-pressure exhaust gas will run into the crankcase when the engine is working, the pressure in the crankcase is very high.

4. It will cause the engine to overheat and produce excessive oil vapor, which may lead to the injection of oil into the exhaust pipe. It should be noted that the exhaust pipe injector oil may be a sudden failure, or it may be caused by long-term unreasonable use or untimely maintenance.If you find the exhaust pipe injection oil, you should check and troubleshoot it in time.

3. Due to excessive wear of the piston ring, piston and cylinder liner. The gas generated during the combustion of the engine entered the crankcase. Severe wear or damage to the exhaust valve will also cause a large amount of exhaust gas to enter the crankcase when the engine is exhausted.If a large amount of exhaust gas cannot be discharged smoothly, the oil will be brought out at the same time as the exhaust.

4. It may be the gas in the cylinder. Maybe the crankcase respirator is blocked. If the exhaust pipe of the car is connected to the upper part, the valve oil seal should be considered. Generally speaking, the exhaust pipe drains oil because of the high pressure of the crankshaft. If it has just been repaired, the organic oil will be stored in the cylinder, and the oil will be discharged in a short time.

5. It will affect the power. Solution: Check whether the PVC one-way valve is blocked. The blockage can be cleaned. Open the oil cap and start the engine to check whether the exhaust gas ejected from the refueling cover is large. If it is too large, it may be a piston ring leakage, resulting in the exhaust pipe spraying oil. If you add too much oil, just release some.

6. It is likely that the crankshaft ventilation valve is aging. It is recommended that users replace the crankshaft ventilation valve.Secondly, it may also be because the wear between the valve rod and the valve duct is relatively serious, resulting in an excessive gap, resulting in the situation of oil.

What's wrong with the motorcycle engine exhaust pipe injection oil

1. The engine exhaust pipe injection oil is probably due to the aging of the crankshaft ventilation valve, or the piston, cylinder liner, piston pin and piston The ring failed, thus losing the original sealing effect, resulting in the phenomenon of oil spraying.

2. The exhaust pipe of the motorcycle engine injects oil outward. First of all, check whether too much oil is added to the engine. If too much oil is added, it will cause excessive pressure in the engine, and too much oil will be sprayed out of the exhaust pipe.

3. The oil leakage of the motorcycle exhaust pipe is usually caused by the aging of the crankshaft exhaust valve or the failure of the piston and cylinder liner. If the oil leaks, in addition to checking whether there is too much refueling or whether the gasoline seeps into the oil, it is also necessary to check whether the cylinder pad is broken, the combustion chamber pressure enters the engine, and the oil is squeezed out of the exhaust pipe.

4. The possible reason why Yamaha motorcycle injects oil from the exhaust pipe of the engine is that too much oil is added in the engine. The gasoline leaks into the engine and mixes with the oil, resulting in more and thinner oil, the cylinder pad is damaged, the pressure in the combustion chamber enters the engine, and the pressure is too high. The exhaust pipe is squeezed out, etc.

5. The exhaust pipe reduces the internal pressure of the engine. When exhausting exhaust, there may be a little oil, but very little. If you obviously spray engine oil, it may be because you added too much engine oil!.

6. It's the cylinder that is blowing; it's the crankcase respirator blocked. Check it accordingly. If the exhaust pipe of some vehicles is connected to the upper part, the valve oil seal should be considered. It is recommended to check it.

How many reasons are there for the injection of oil in the exhaust pipe of the Weichai six-cylinder engine?

1. Because the throttle valve accumulates too much carbon. The engine is the power source of the car. Most of the car engines are thermal power devices, referred to as thermal engines. The thermal machine converts the thermal energy generated by fuel combustion into mechanical energy by using the state change of the work quality.

2. There are nine reasons for the injection of engine exhaust pipe: the engine oil is sprayed out due to cylinder leakage. In this case, the engine is usually overhauled, which requires professionals from the 4S store.The crankcase respirator ruptured, resulting in oil injection. In this case, disassemble the engine and replace the new respirator.

3. There are many reasons why the exhaust pipe will suddenly spray a large amount of oil, and the most likely is that the crankshaft ventilation valve is aging. Secondly, excessive wear of the piston, cylinder liner and piston ring will cause the engine to lose its original sealing performance. The oil is easy to enter the cylinder, and then the oil is sprayed out of the exhaust pipe with the exhaust gas.
