What should I do if the throttle opening becomes larger? What caused it?

Because cars are also consumables, they need frequent maintenance. A well-maintained car can extend its service life for several years, and a poorly maintained car has a shorter service life, so many people say that the car is like a person. Please take care. Some simple maintenance can be solved by many car owners themselves, but for some complicated maintenance, most people choose to go to 4S shop for maintenance, but some people find that the fuel consumption of the car after maintenance is higher. What is the reason for opening a 4S shop? Let's take a look at them.

Usually, because the car has completed various adjustments and needs to adapt to the process, after a certain maintenance period, the fuel economy is usually high. As long as the data is turned on for a period of time, the data will return to normal and the fuel consumption will be the same. Your car habit hasn't changed. Even if you drive for a while, if you just improve fuel economy, there will be problems.

Too much oil.

The increase of fuel consumption may lead to the increase of resistance due to the increase of fuel quantity. Do you think the resistance will increase when the engine is running, but the fuel consumption will not increase? So the oil is used up, so be sure to check it yourself. If you can't trust the captain completely, they will be careless.

Add the wrong type of oil.

There are also many kinds of engine oils. The difference is that they have different characteristics. Some oils have high viscosity, while others have low viscosity. When changing oil, adding high viscosity oil will increase resistance and fuel economy. Generally do not change the oil at will. What oil did you add before? What oil are you still using now? There is nothing wrong with adding according to your request.

Spark plugs are not installed.

Spark plugs play a very important role. After gasoline enters the engine, it becomes mixed combustible gas, which is used to ignite the mixed combustible gas of gasoline engine. So, if the spark plug is broken, the engine will be a problem. If the spark plug is used for a long time, it must be replaced with a new one. When replacing the spark plug, if the spark plug with poor quality is used, or the spark plug is not installed correctly, the engine will become fat, can not run well, and increase fuel consumption.

Throttle opening increased

The maintenance of the throttle is also very important. Dirt is easy to accumulate on the throttle, which hinders the opening and closing of the throttle to some extent. When the throttle is blocked by dust, the opening becomes smaller. The on-board computer increases the throttle opening to ensure the normal control of air intake and fuel injection, but it will not interfere with the throttle after cleaning the throttle. When things open and close, the throttle valve keeps the previously set opening, resulting in a larger opening and increased fuel consumption. Conclusion: It is normal to increase gasoline after automobile maintenance. In most cases, the car will stop for a while, so it will slowly return to its previous normal state. If the fuel consumption has not decreased for a period of time, it is necessary to check the above problems.
