About the maintenance of gasoline filter, you also need to know these!

If you want the car to run well, regular maintenance cannot be less. Oil filter, air filter and gasoline filter, these need to be replaced in time. However, I believe that many people are familiar with machine filter and air filter, but ignore the steam filter. So, what is the steam filter? How often should the steam filter be replaced? Let's take a look.

What is steam filter

Steam filter, the full name of gasoline filter, is called "the kidney of the engine". It is a kind of fuel filter. It filters fuel impurities, provides clean fuel for the engine, and protects the engine and fuel supply system. important auto parts.
Because the engine will produce a large amount of carbon deposits, gums, sludge, metal wear debris, etc. during operation, these impurities are mixed in the engine oil. If they are not filtered out, they will aggravate the wear of the engine. Therefore, it is necessary to filter these impurities and keep them on the filter paper of the steam filter, so that the engine can get clean oil.

According to the fuel supply method, gasoline filters can be divided into two types: carburetor type and electronic injection type. After 2000, carburetor type filters have basically disappeared in passenger cars because of their backward methods. Mainly electronic injection. According to the structural characteristics, it can be divided into three types: ordinary straight-in and straight-out type, with oil return pipeline type and integrated oil pump type.

How long does it take to replace the steam filter?

The replacement cycle of the gasoline filter depends on the cleanliness of the vehicle in daily use. Generally speaking, the gasoline cleanliness is not good, and the gasoline filter needs to be replaced in advance; the gasoline is relatively clean, and the replacement time can be appropriately delayed. The theoretical replacement cycle of most built-in gasoline filters is 40000 kilometers, and the external one is 20000 kilometers. It needs to be replaced according to the mileage specified in the maintenance manual.

In addition, it should be noted that if the following phenomena occur in the car and other reasons are ruled out, your gasoline filter may be dirty or clogged, and it is time to change it.
 

0 1. The rapid acceleration is weak, and the power drops significantly when the car is running with a large load
Slightly clogged gasoline filter element will generally cause poor fuel supply to the engine, resulting in a decrease in engine power.
 

0 2. It is difficult to start or the car cannot be started directly.
When the gasoline filter is severely clogged, the car will have difficulty in starting or even unable to start, such as sometimes it takes 2-5 times to start.

0 3. Engine jitter when idling

A moderate blockage of the gasoline filter element will not only make the power of the car worse, but also cause the engine to shake when the car is idling.

Of course, the above failure phenomena all need to be determined to be a gasoline filter problem after other failures are eliminated, because the failure phenomenon caused by the gasoline filter problem is similar to the fuel system failure (such as blocked fuel injector, etc.).
