Engine cylinders are essential components of an internal combustion engine. They are hollow tubes where fuel and air mix and ignite, creating pressure that pushes a piston. This movement of the piston converts the energy from the combustion into mechanical power, which ultimately drives the vehicle. Each engine typically has multiple cylinders, often arranged in a line or a V-shape, depending on the design. The number of cylinders can affect the engine's power and efficiency. Common configurations include inline, V, and flat engines, each offering different performance characteristics and benefits for vehicles.
