What does 2.0 fuel consumption mean?

[DeAvery]

It refers to the displacement. A 2.0 displacement means the sum of the working volumes of all cylinders. Here are the relevant details: 1. Displacement: A specialized term in hydraulic transmission, referring 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, indicating better power performance. Therefore, off-road vehicles and sports cars usually have relatively large displacements. The working volume through which the piston moves from top dead center to bottom dead center is called the cylinder displacement; if the engine has multiple cylinders, the sum of the working volumes of all cylinders is called the engine displacement, usually expressed in liters. Engine displacement is one of the most important structural parameters, representing the size of the engine more accurately than bore diameter and number of cylinders. Many engine indicators are closely related to displacement. 2. Fuel consumption: Constant-speed fuel consumption is the vehicle's fuel consumption per 100 kilometers obtained in constant-speed driving fuel consumption tests specified by national standards for certain types of vehicles.
