What Happens If a Car Doesn't Have an Air Filter?
1 Answers
If a car doesn't have an air filter, dust and sand can be sucked into the combustion chamber, causing valve wear and leakage, insufficient cylinder pressure, and power loss. It also accelerates wear on the cylinder liner, piston, and piston rings, leading to increased gaps and oil burning. Below are the impacts of not replacing the air filter. Engine Wear: It accelerates engine wear and carbon buildup. If the vehicle is driven without an air filter, dust directly enters the cylinder and mixes with the fuel-air mixture for combustion. This results in cylinder wear eight times greater than in vehicles with an air filter, piston wear three times greater, and piston ring wear nine times greater. Dirty Engine Intake: Long-term use of a damaged air filter allows dust not only to enter the engine but also to invade the engine's intake tract, making it dirty. Decreased Filtration Efficiency: If the air filter isn't too dirty, it can be cleaned with an air gun. When blowing, ensure to blow from the inside out. However, most air filters are made of coarse filtration, low-air-resistance materials. During driving, the filter creates resistance to airflow. When dust accumulation exceeds a certain level, the filter's resistance increases, and filtration efficiency decreases.
