What Does Intake System Cleaning Include?
2 Answers
Intake system cleaning includes the air filter, mass air flow sensor, intake pressure sensor, throttle body, auxiliary air valve, idle air control valve, resonance chamber, power chamber, intake manifold, etc. Additional information: Functions of the intake system: 1. To deliver clean, dry, sufficient, and stable air to the engine: The primary function of the intake system is to supply clean, dry, sufficient, and stable air to meet the engine's requirements, preventing impurities and large particles from entering the engine combustion chamber and causing abnormal wear. 2. To reduce noise: Another important function of the intake system is noise reduction. Intake noise not only affects the overall vehicle pass-by noise but also impacts cabin noise, which significantly influences ride comfort.
Recently, my car has been feeling sluggish when accelerating, and stepping on the gas pedal didn't provide much power, so I went for an intake system cleaning. The entire cleaning process mainly included cleaning the throttle body, the inside of the intake manifold, the intake passages, and the areas around the air filter. The throttle is a key component controlling air intake and is prone to carbon buildup, which can cause blockages; the intake manifold often accumulates sludge, affecting airflow. I personally watched the technician spray specialized cleaning agents and sometimes even use a small brush for manual scrubbing. After the cleaning, the car drove much smoother, with faster throttle response and slightly reduced fuel consumption. Driving in the city with frequent stops and starts, carbon buildup is inevitable. I recommend checking it every 10,000 to 20,000 kilometers to prevent small issues from turning into major problems. This also benefits the engine's lifespan and saves unnecessary repair costs.
