Do you know the gasoline filter? Why haven't 90% of car owners changed their cars?

Car owners are quite familiar with oil filters, air filters and air conditioning filters, but gasoline filters are often overlooked. So, what is a gasoline filter? How often should the air filter be replaced? Now, let's sort out some matters related to gasoline filters. The gasoline filter, also known as the air filter, is a type of fuel filter that filters impurities from the fuel to provide clean fuel for the engine, protecting important automotive components of the engine and fuel supply system.

During the production, storage, transportation and use of gasoline, certain impurities such as iron oxide and dust will inevitably contaminate the gasoline, or the quality of the oil in some gas stations is already very poor. Contains a large amount of impurities. If these impurities are not filtered out and carried into the engine and fuel supply system, they may damage the cylinders or clog the fuel injectors. It's time for the gasoline filter to come into play. The filter elements of automotive filters are generally divided into two types: one is the in-line fuel filter, and the other is the built-in fuel filter. The most common type we see is the in-line fuel filter, which is located outside the fuel tank and connected to the fuel inlet pipe. The main function of the fuel inlet pipe is to supply fuel to the engine. The greatest advantage of the in-line fuel filter is its ease of replacement. The built-in fuel filter is located in the fuel tank and is difficult to replace, resulting in high maintenance costs. However, gasoline has a high pass rate and is not prone to clogging. However, the drawback is that replacing it is very troublesome. If you want to replace it, you must open the fuel tank first. If you are not a professional operator, it is very easy to damage the car.

How often should it be replaced?

The replacement cycle of the gasoline filter is relatively long, generally 30,000 to 50,000 kilometers. It needs to be replaced according to your maintenance manual or actual usage conditions. Meanwhile, it also depends on the quality of gasoline used in daily life. If the impurity content of the fuel is relatively high, the possibility of the gasoline filter getting clogged will increase significantly, and the replacement cycle will be appropriately shortened. It is equally important to note that if the following phenomena occur in your car and other causes are eliminated, your gasoline filter may be too dirty or clogged. Now it is time to replace it.

When a car is driving under heavy load, the acceleration is weak and the power drops significantly: A slight clogging of the gasoline filter element usually leads to insufficient fuel supply to the engine, resulting in a decrease in engine power.

Engine shaking at idle: A slight clogging of the gasoline filter element not only fails to reduce vehicle power but also causes engine shaking at idle.

Difficulty in starting or inability to start the car directly: When the gasoline filter is severely clogged, the car will be difficult to start or even impossible to start. Sometimes it takes 2 to 5 times to start.

Of course, before determining the problem with the fuel filter, other fault phenomena need to be eliminated. The fault phenomena caused by the fuel filter problem are the same as those of the fuel system (such as nozzle blockage, etc.). Finally, I would like to remind all car owners that most engines are equipped with disposable, non-detachable paper gasoline filters. When replacing the gasoline filter, please be sure to purchase a high-quality filter and follow the manufacturer's instructions. If a poor-quality filter element is used, not only will the material quality be poor, but the filtration effect will also be poor. If the filter element is soaked in gasoline for a long time, the filter layer will fall off and clog the oil passage. This will lead to abnormal pressure in the fuel system, which will directly result in insufficient engine power or incomplete combustion. The result will surprise you!
