Flywheels are heavy rotating mechanical devices connected to the engine's crankshaft, primarily serving to smooth out the delivery of power and maintain rotational momentum. Located within the engine's crankcase, these components accumulate energy during the engine's power stroke and release it during other strokes, reducing vibrations and ensuring consistent engine operation. Flywheels are essential for starting the engine, as they provide the initial rotational force required to overcome compression. They also commonly incorporate a ring gear for the starter motor to engage with. Examples within our range include Febi flywheel FEBI102298 for various passenger car applications, heavy-duty Volvo Trucks flywheels for commercial vehicles, and SACHS flywheel 3421601084 designed for performance and durability.
