What is the cause of oil leakage in the range extender of electric vehicles

<>5kw low-speed electric vehicle range extender.

It should be that there is a problem with the carburetor, and the carburetor needs to be cleaned, and if the problem is not solved after cleaning, the carburetor needs to be replaced.

Because the cruising range of low-speed electric four-wheeled vehicles is still relatively limited, can not fully meet the daily travel needs of the public, if you want to increase its cruising range, you can install a range extender, in order to increase its cruising range, increase its range of activities, meet the daily travel needs of the public, and realize the freedom of travel, no longer due to the lack of power halfway and difficult.

The range extender can be purchased directly from the manufacturer, and the manufacturer will ship it directly, which will be cheaper. It is necessary to choose a range extender produced by a large manufacturer and a big brand to have a comprehensive guarantee of quality, performance, technology, after-sales and so on, otherwise if it is a small workshop-type manufacturer, it is easy to break and there is no guarantee in all aspects.

Recommendations for the use of range extenders:

It is not recommended to start the range extender when the battery is full, and it is generally recommended to start it when the battery is only 30%-40%. There is no particularly good effect when starting when the battery is full, in order to be environmentally friendly, it is recommended to start the range extender when needed, battery pollution is more serious than exhaust gas pollution, and protecting the battery is to protect the environment. It is not recommended to use it when the battery is not a little charged, the range extender is electric when it starts, and it may not catch fire when the battery is not charged at all.

It is estimated that the rubber seal is broken, so take it apart and take a look at it yourself, and replace it with a seal of the same specification. Or go directly to the master to repair perhaps, the cost of a few yuan, it should be normal.

I don't know what kind of range extender you're using. Where is the oil leak? Oil or Fuel?

Let's say you're using a normal range extender. This type of range extender is generally used with a generic engine. The characteristic is that it is not optimized for the environment where the car is shaking.

A common problem is that the structure of the carburetor is prone to fuel leakage when it shakes. Because the range extender is not like other engines. Most of them are in a stopped state and are only used in an emergency.

The car will shake when it is used, and if the shake is large, there will be fuel leakage. And it can't be used in time. After a long time, you will see a large amount of fuel spills.

1. The oil leakage is caused by the failure of the rubber seal on the engine.

2. The engine is not a whole, the engine is composed of valve chamber cover, cylinder head, cylinder block and oil pan from top to bottom. Then between these components is connected by a royal spiral. The seals between these parts are sealed with gaskets, some of which are made of rubber.

Then the temperature of the engine is relatively high during normal operation, and the pressure in the cylinder is also very large, and the rubber gasket is easy to become brittle and hard when working in this high-temperature and high-pressure environment for a long time, which will lead to a decrease in sealing performance, and the engine will have oil leakage.

3. There are also many rubber gaskets in other parts of the engine, such as the oil cooling system of the engine. This cooling system is designed to reduce the temperature of the oil, so some of the pipes of this cooling system have rubber gaskets at the interfaces. The temperature of the engine oil is very high, and the rubber gasket working at this high temperature for a long time will also lead to a decrease in sealing performance, so this position is also more prone to oil leakage.

Summary. This depends on whether your range extender is a carburetor or an EFI engine, if it is a carburetor engine, it is mainly because of the carburetor problem, generally speaking, you need to check whether the carburetor oil supply line is normal, if there is no problem with the oil supply, you can consider replacing a carburetor. If it is an EFI engine, then you should check whether your injector is blocked, and also check whether the spark plug is ablated and can replace a spark plug.

If there is no problem with the fuel supply and ignition of the engine, then you need to check whether the cylinder pressure of the engine is normal, which can be determined by measuring the cylinder pressure.

It can start automatically, but the pedal can't be refueled, and the pedal doesn't respond.

Then you go on the range extender and look at the cable on the carburetor, and pull it to increase the starting speed.

It's the kind of stepper that doesn't pick up the line.

Then you may have a broken pedal position sensor.

But the electric car can walk by pedaling.

Can you increase the speed of your range extender when you step on the accelerator? Like a lot of range extenders, the speed is fixed.

It can be added, but it is not fixed.

If you can add it, then you should consider replacing your control motor.

Is that the little motor on the carburetor? Yes.

Summary. Hello, Car Master Mechanic is here to serve you. Attentive, careful, attentive, for you to answer the car fault problems, for you to find the corresponding problem solutions and maintenance methods.

We will provide you with a satisfactory answer to your questions, I hope this service can help you, if it is helpful to you, I look forward to your praise and attention. I wish you good luck and good luck in the Year of the Tiger, Hello friends, the routing of electric vehicle motors is due to the failure phenomenon caused by this poor sealing, and the problems caused by the aging of the sealing ring. The solution is to dismantle the motor again and replace the original imported sealing ring to solve your problem.

If the failure is caused by the aging of the seal, it is enough to replace the seal.

Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

I wish you good luck in the Year of the Tiger, good luck, Hello friends, the routing of electric vehicle motors is due to the failure phenomenon caused by the poor dismantling of the chain and the aging of the sealing ring. The solution is to dismantle the motor again and replace the original imported sealing ring to solve your problem. If the rubber is caused by the aging of the seal, it is enough to replace the seal.
