The engine displacement of a car refers to the volume of fluid inhaled or discharged per stroke or cycle, describing the size of the engine, usually referred to as displacement or exhaust volume. The following is extended content: 1. Car displacement is an important structural parameter for measuring a car, which can represent the size of the engine more accurately than the cylinder bore and the number of cylinders. Many indicators of the engine are closely related to the displacement. 2. Generally speaking, cars with larger displacement are bigger in size, and the energy released by the engine per unit time is greater, which means better power performance. 3. Car displacement is usually expressed in liters, and the size of the displacement can generally be found on the corresponding label at the rear of the car body. Different car models may have different representation methods.
