Do Cars with Larger Displacement Consume More Fuel?

[SophiaLee]

Vehicles with larger displacement do not necessarily consume more fuel; it depends on the engine's manufacturing technology. Comparison conditions: Under the same conditions such as vehicle weight, aerodynamic design, mechanical efficiency, engine technology, driving habits, road conditions, etc., cars with larger displacement will consume more fuel. Displacement aspect: Displacement (Swept-volume), a specialized term in hydraulic transmission, refers to the volume of fluid inhaled or discharged per stroke or cycle. Generally, a larger displacement means the engine releases more energy per unit time (converting the chemical energy of fuel into mechanical energy).
