Does the Throttle Affect Fuel Consumption?
2 Answers
High fuel consumption in cars is not related to the throttle. The factors that affect a car's fuel consumption are as follows: 1. Transmission: The transmission is a power-speed adjustment device connected between the engine output and the wheel drive shaft. Its basic functions are: changing the corresponding "power-speed" combination according to the car's driving needs, altering the speed direction (reverse gear), and disconnecting the engine from the drive shaft (idle). 2. Vehicle Weight: The heavier the vehicle, the more power is required, naturally leading to higher fuel consumption. 3. Design Factors: This mainly refers to the drag coefficient. Vehicle design is not just about aesthetics but also considers the drag coefficient. The more streamlined and smoother the car design, and the smaller the body attachments, the more effectively the drag can be reduced. The lower the drag coefficient, the lower the vehicle's drag, the better the stability, and the more fuel-efficient it is. Generally, a 10% reduction in drag coefficient can lower fuel consumption by 3%. 4. Tires: Tires have a direct impact on a car's fuel consumption. The wider the tread and the larger the tread pattern, the greater the friction generated, leading to increased fuel consumption.
Yes, the throttle body definitely affects fuel consumption. Over my years of driving, I've encountered this situation multiple times: fuel consumption inexplicably rises, accompanied by sluggish acceleration and unstable idling. After taking it to the repair shop, the mechanic diagnosed it as severe carbon buildup in the throttle body causing restricted opening, which reduces air intake. As a result, the engine compensates by injecting more fuel to maintain the air-fuel mixture, leading to wasted fuel. If not cleaned promptly, fuel consumption can increase by 10% to 20%. I recommend paying attention to this issue during daily driving. If you notice abnormal fuel consumption, check the throttle body condition. Regular maintenance cleaning is low-cost but can save significant fuel expenses. Though throttle body issues may seem minor, they actually greatly impact overall vehicle efficiency. Develop good habits, such as having professionals clean it every 20,000 kilometers to ensure proper valve opening and smooth engine breathing, which naturally reduces fuel consumption. This not only saves money but also makes driving safer and more reliable.
