Riesci davvero a distinguere i quattro elementi del filtro?

 

When many car owners and friends go to the 4S shop for maintenance, they may have heard the terms of air filter, filtro macchina, steam filter, and air conditioning filter from the reception staff and maintenance technicians, but the names are very similar, and they all have Each has different maintenance periods and features, and the prices are also different, so it is often easy to confuse them and make the difference unclear.

 

 

1. Machine filter (full name oil filter)

The machine filter is mainly composed of filter paper, sealing ring, backflow suppression valve, overflow valve and other structures. In genere, it is replaced simultaneously with the maintenance cycle of the oil. It is mainly used to filter the oil impurities to ensure the normal lubrication function of the engine. In the process of automobile engine use, it is inevitable that there will be impurities such as metal chips, polvere, carbon deposits, moisture, oil oxidized colloid, eccetera. The oil filter will filter them out and play a cooling role, thereby prolonging the use of oil Life, to ensure the normal operation of the engine.

Maintenance period: same oil, every 6-12 months or 5000-10000km (time and mileage shall prevail)

 

 

2. Filtro dell'aria (full name air filter)

The function of the air filter is like a mask. It is mainly to purify the air that enters the engine and reacts with the fuel, so as to protect valuableheartcomponents such as cylinders and pistons from wear. Dust, particles, and particulate impurities suspended in the air are dangerous to enter the engine directly without filtering. Nei casi più gravi, it will cause the phenomenon of cylinder pull between the piston and the cylinder, causing greater damage to the engine.

 

 

Air filters are generally installed near the air intake of the engine. There are two types: filter paper type and oil bath type. The filter paper type has low cost, high filtration rate and convenient maintenance. It is widely used in various family cars.

Maintenance cycle: every 1 year or 10000-20000 chilometri

 

3. Air conditioning filter (full name air conditioning filter)

Many people easily confuse air filters with air conditioning filters. Infatti, air conditioning filters are mainly used in the car’s air conditioning system to filter the air that enters the car from the outside, so that impurities, polvere, polline, and small particles in the air are isolated. Inoltre, some high-end air-conditioning filters can also filter out PM2.5, creating a healthier and sanitary environment for the occupants in the car.

 

 

The replacement of the air-conditioning filter is relatively simple. Per la maggior parte dei modelli, the installation location can be found near the glove box in front of the co-pilot. Xiaobang reminds that if it is in an environment with relatively heavy sand or high humidity, the air-conditioning filter should be replaced more frequently. Do not wait until the air-conditioning in the car is turned on and there is a peculiar smell.

Maintenance cycle: every 10,000-20000 chilometri (recommended to be replaced during alternate seasons)

 

 

4. Filtro vapore (full name gasoline filter)

Gasoline filter is a kind of fuel filter. It filters fuel impurities, provides clean fuel for the engine, and protects the engine and fuel supply system. In the process of gasoline production, storage and transportation, certain impurities such as iron oxide and dust will inevitably be generated, or the quality of the oil at some petrol stations is inherently poor and contains a lot of impurities. If these impurities are not filtered out, they will be brought with you. If it enters the engine and fuel supply system, it may damage the cylinder or block the fuel injector.

If the gasoline filter is too dirty or clogged, it is mainly manifested as: when the gas is added, the power is slow, or cannot get up, the car is difficult to start, sometimes it takes 2 per 5 times to hit the fire. Most engines are equipped with disposable non-removable paper filter gasoline filters. When replacing gasoline filters, you need to follow the manufacturer’s guidelines.

Maintenance period: every 10000-20000 chilometri

 

 

Summary:

Air filters, gasoline filters, and oil filters are all cleaning components for the engine system, while the air-conditioning filter is to ensure fresh air in the car. Although thesefour major filtersare filtering impurities , But their filtering objects and functions are still very different, and the filtering standards are also very different.

Car maintenance must strictly follow the replacement cycle in the car maintenance manual, and even thefour filterscan be replaced in advance according to the car environment. Inoltre, don’t be greedy to buy Sanwu products at a small price, and the final filtering effect will not meet the standard, causing greater losses and troubles!
