What is Engine Displacement?

[DeCooper]

Engine displacement, a specialized term in hydraulic transmission, refers to the volume of fluid inhaled or discharged per stroke or cycle. Below are specific details about engine displacement: 1. Cylinder displacement and engine displacement: The space volume through which the piston moves from top dead center to bottom dead center is called cylinder displacement; if the engine has multiple cylinders, the sum of the working volumes of all cylinders is called engine displacement. It is generally expressed in liters (L). 2. Displacement classification: The classification of passenger cars in China is determined by the size of the displacement. The displacement of a mini car is less than or equal to 1.0L; the displacement of a compact car ranges from 1.0 to 1.6L; the displacement of a midsize car ranges from 1.6 to 2.5L; the displacement of an executive car ranges from 2.5 to 4.0L; and the displacement of a luxury car is greater than 4.0L.
