What is the displacement of a 0.97 engine?

[DeBlakely]

An engine displacement of 0.97 refers to a 0.97L displacement, approximately 48 horsepower. Introduction to displacement: Simply put, it is the total volume of the engine cylinders. The working volume that the piston passes through when moving 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. It is generally expressed in liters (L). Cylinder volume: Because a larger cylinder volume (displacement) can accommodate more combustible mixture (air-fuel mixture), under all other conditions being equal, an engine with a larger cylinder volume (displacement) will inevitably have better/higher power/fuel consumption.
