Does Higher Horsepower Always Mean Higher Fuel Consumption?
1 Answers
A larger displacement can provide greater power, which also increases the demand for fuel. It is inevitable that higher displacement leads to higher fuel consumption. The so-called special cases only occur when comparing different vehicle models, as differences in design focus and technical factors mean that even with the same displacement, fuel consumption can vary between models. For the same model, a higher displacement will always result in higher fuel consumption than a lower one. Excessive Carbon Buildup in the Vehicle: Carbon buildup typically occurs in the throttle body, fuel injectors, intake manifold, and piston tops. Excessive carbon deposits in any of these areas can lead to incomplete combustion, thereby increasing fuel consumption. The first five items do not show obvious fault symptoms, and the driver may not notice any abnormalities. Only excessive carbon buildup will exhibit clear fault symptoms, such as engine shaking, sluggish acceleration, and difficulty starting. Therefore, if these symptoms appear, carbon buildup should be considered first, and timely repairs are necessary. Insufficient Tire Pressure: Low tire pressure increases the contact area between the tires and the road, leading to greater friction and driving resistance, which in turn raises fuel consumption. Insufficient tire pressure also shortens tire lifespan and increases the risk of a blowout during high-speed driving. Therefore, tire pressure should be checked regularly, at least once every two months. If the vehicle is equipped with a tire pressure monitoring system, the pressure can be checked directly. Otherwise, a tire pressure gauge should be used to manually measure each tire.
