What are the three filters in an engine?
2 Answers
Automotive three filters refer to the air filter, fuel filter, and oil filter. The specific introductions are as follows: 1. Air filter: There are many dust particles suspended in the air, and the main component of these suspended particles is silicon dioxide (Sio2), a substance harder than metal. Installing an air filter can reduce wear on parts such as cylinders, pistons, and piston rings. 2. Oil filter: During the use of an internal combustion engine, mechanical impurities such as dust, metal shavings, and carbon deposits will continuously mix into the oil. At the same time, the oxidation effect of air and combustion exhaust gases on the oil will gradually cause the oil to produce gum. The mixture of mechanical impurities and gum can also form sludge, which not only accelerates the wear of moving parts but also easily causes oil passage blockage. 3. Fuel filter: During the storage, transportation, and refueling process, gasoline is inevitably mixed with some mechanical impurities and water. These impurities enter the fuel supply system and engine cylinders along with the fuel, accelerating cylinder wear.
Every time my friends ask me what the three filters in an engine are, I tell them it's pretty simple. The three filters refer to the air filter, oil filter, and fuel filter—three key components. The air filter is responsible for filtering the air entering the engine to prevent dust from messing up combustion. The oil filter cleans impurities from the engine oil to prevent wear on the components. The fuel filter filters out dirt in gasoline or diesel to ensure the fuel system stays clean. I once drove an old car and neglected to change the air filter, which resulted in the engine making loud noises and fuel consumption skyrocketing. The mechanic said it was all due to dust clogging it up. It's recommended to check them every 10,000 kilometers or every six months. After replacing the filters, the car runs much smoother, and the engine's lifespan can be significantly extended—just don’t procrastinate like I did.
