In auto parts, oil filter, air filter, air conditioning filter, fuel (gasoline/diesel) filter, referred to as four filter
Filters, they are mainly responsible for filtering impurities, not for the lubrication system, air intake system, air conditioning system, and fuel supply system.
oil filter
1. Function: filter the impurities contained in the lubricating oil and keep the oil clean.
2. Service cycle: It needs to be replaced regularly when driving 5000-10000KM, and it should be replaced together with lubricating oil every time.
3. What is the impact: The quality and working conditions of the oil filter determine the cleanliness of the oil, and if it is not replaced regularly or the filter is of poor quality, it will indirectly lead to excessive mechanical wear.
air filter
1. Function: filter the dust in the air and keep the intake system clean.
2. Service cycle: The dust environment area determines the replacement cycle, and it is generally replaced once after driving 20,000 to 30,000 kilometers.
3. What is the impact: blockage will cause increased fuel consumption, insufficient power, and indirectly lead to excessive mechanical wear.
air conditioner filter
1. Classification: ordinary filter paper, carbon ion, activated carbon, etc.
2. Function: filter the air-conditioning system intake impurities and dust, and improve the air quality in the car.
3. Use cycle: The replacement cycle depends on the region, environment, and mileage. Generally, it is replaced every 20,000 to 30,000 kilometers.
4. What is the impact: the air quality in the cab, due to insufficient air passage, affects the heating and cooling quality of the air conditioner.
Fuel Filter
1. Function: filter the impurities contained in the fuel, keep the oil clean, ensure the smooth flow of the oil circuit, and meet the oil pressure requirements
2. Service cycle: There are two types of fuel tank built-in and external models. Generally, the built-in filter is replaced at 20,000-30,000 kilometers, and the built-in filter is replaced at 50,000-60,000 kilometers. There is also no time limit requirement.
3. What is the impact: Insufficient fuel pressure, insufficient engine power, difficulty in starting, and increased fuel consumption.
