What does 1.8L mean?

[OKiara]

Engine 1.8L means that the car's displacement is 1.8 liters, where L stands for liters. Car displacement is an important parameter to measure a vehicle, and the displacement is usually marked on the body or rear of the car. Car displacement refers to the volume of fluid inhaled or expelled per cycle. Displacement consists of three parts: the first part is composed of 2 or 3 pinyin letters, which are codes identifying the manufacturer's name. Following the pinyin letters are usually 4 Arabic numerals. For passenger cars, the first digit on the left is "7," and the middle two digits represent the engine displacement of that car model. For example, "08" indicates an engine displacement of 0.8 liters, and "2.0" indicates 2.0 liters. After the digits representing displacement, there is another digit indicating the manufacturer's self-defined product sequence number. The classification of passenger car levels is determined by the size of the displacement: mini cars have a displacement of ≤1.0L; compact cars have a displacement ranging from 1.0—1.6L; midsize cars range from 1.6—2.5L; executive cars range from 2.5-4.0L; and luxury cars have a displacement >4.0L.
