What does the number of cylinders in an engine mean?

[MacLane]

The cylinder in an engine refers to the combustion chamber. A cylinder is a cylindrical cavity within the engine where a piston moves under the pressure or expansion force of the working fluid. The cylinder and cylinder head must be assembled together to form the combustion chamber. An engine typically has multiple cylinders. The sum of the working volumes of all cylinders is called the engine displacement, measured in liters (L). Here is some relevant information about car engines: Introduction: A car engine is the device that provides power to the vehicle, acting as the heart of the car, determining its power, fuel efficiency, stability, and environmental performance. Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines. Classification: Based on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid engines, among others.
