What are the Three Automotive Filters?

[EmmanuelMarie]

Automotive three filters, also known as the three core components, refer to the air filter, fuel filter, and oil filter. The regular maintenance of a car mainly involves the replacement of these three filters. These filters play a crucial role in the car's engine by filtering air, oil, and fuel, thereby protecting the engine. The functions of the three filters are: 1. Air filter: Ensures the air entering the engine is clean; 2. Fuel filter: Ensures the fuel is clean and prevents vapor lock; 3. Oil filter: Filters the engine oil to ensure the engine operates smoothly. During the use of an internal combustion engine, mechanical impurities such as dust, metal shavings, and carbon deposits continuously mix into the oil. Additionally, the oxidation of oil by air and combustion exhaust gases gradually forms sludge. This sludge, a mixture of mechanical impurities and oxidized oil, not only accelerates the wear of moving parts but also easily clogs the oil passages.
