Benefits and Functions of Throttle Cleaning

The specific introduction to the benefits and functions of throttle cleaning is as follows: 1. Remove carbon deposits. The benefit of regular throttle cleaning is to remove carbon deposits, improve the precision of air intake and fuel injection, and enhance fuel efficiency. 2. Extend the engine's service life. Not cleaning the throttle for a long time will cause throttle opening errors and allow impurities in the air to enter the engine combustion chamber. 3. Function of the throttle. The throttle is a controllable valve that regulates the air entering the engine. After the air enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to generate power. The throttle is connected to the air filter at the top and the engine block at the bottom, and is known as the throat of the automobile engine.

After driving my previous car for over 30,000 kilometers, I noticed the engine seemed to struggle for breath during acceleration. Getting the throttle body cleaned felt like getting a brand-new car. When they opened it up, the valve plate was completely covered in black, sticky sludge deposits, blocking the intake passage to barely the width of a pinky finger. The mechanic said this component acts like the engine's throat - when clogged, it causes sluggish throttle response, unstable idling, and even makes cold starts difficult. The most noticeable improvement after cleaning was the reduced fuel consumption - my actual measurements showed nearly 1L less per 100km. The throttle response became much sharper, and the engine stopped that annoying rattling vibration. Regular cleaning genuinely extends engine lifespan, especially for drivers frequently stuck in urban traffic. I'd recommend checking it every 20,000 kilometers.

Cleaning the throttle body by yourself is actually quite simple. I just sprayed it with carburetor cleaner last weekend. Thick carbon deposits can affect the rotation of the throttle plate, leading to inaccurate air intake and causing the ECU to misfire the fuel injection. The most noticeable improvement after cleaning is the stable idle speed. Before, the steering wheel would shake at red lights, but now it's as steady as a rock. Fuel consumption does drop a bit—a friend measured a saving of 0.8 liters per 100 km after cleaning. However, be careful not to buy cheap, low-quality cleaners to save money. Damaging the coating on the throttle plate shaft would be counterproductive. Generally, cleaning it every 30,000 to 40,000 kilometers is about right.

The most noticeable effect of cleaning the throttle body is that the accelerator pedal feels more responsive. Before cleaning, there was always a half-second delay when pressing the accelerator during acceleration, but that lag has basically disappeared after cleaning. The principle is simple: carbon deposits can jam the throttle plate, preventing it from rotating smoothly, which leads to unstable air intake and naturally affects power output. Idle vibrations will also improve, especially in older cars that shake like massage chairs. Although manufacturers recommend regular cleaning, I believe it depends on the driving environment. Cars that frequently drive on highways might only need cleaning every 50,000 kilometers, while those often stuck in traffic should consider cleaning every 30,000 kilometers for safety.
