Does the throttle affect fuel consumption?
2 Answers
Throttle does not affect fuel consumption. The following factors influence fuel consumption: 1. Transmission: In fact, the type of transmission and the number of gears have a significant impact on a car's fuel consumption. Among them, MT transmissions are the most fuel-efficient, followed by CVT, then DCT and AMT, with AT being the least fuel-efficient. 2. Vehicle weight: The heavier the vehicle, the more power is required, naturally leading to higher fuel consumption. Therefore, it is advised to choose a vehicle based on actual needs. 3. Tires: Tires have a direct impact on fuel consumption. The wider the tread and the larger the pattern, the greater the friction generated, which increases fuel consumption.
With over thirty years of experience driving various car models, I can attest that the throttle body has a direct impact on fuel consumption. If carbon buildup or sticking occurs in the throttle body, the opening angle becomes inaccurate. The engine control unit then mistakenly assumes more air intake is needed, leading to excessive fuel injection and a noticeable increase in fuel consumption. I’ve encountered this issue several times myself—cleaning the throttle body immediately lowered fuel consumption, saving me a significant amount of money. Regular inspection and cleaning of the throttle body are essential; doing it every 20,000 to 30,000 kilometers is sufficient. Don’t wait until the problem becomes severe. Driving habits also play a crucial role—avoid hard acceleration by stomping on the gas pedal, as smooth throttle operation helps minimize fuel fluctuations. Neglecting it will result in a gradual rise in fuel consumption and environmental pollution, which is ultimately not worth it in the long run.
