Semi Centrifugal Clutches used in high powered engines and racing car engines where clutch disengagements require appreciable and tiresome drivers effort. The power transmitted with partly by clutch springs and remaining by the centrifugal action of an extra weight provided in the system.
The clutch springs transmit power at low engine speed and the centrifugal force transmit power at higher engine speed.
Besides clutch, pressure plate and splines shaft it mainly consists of:
When the engine at low speed the spring keeps the clutch engaged to transmit power, the weighted levers do not have any pressure on the pressure plate.
When engine at high speed the weights fly off and levers exert pressure on the pressure plate which keeps the clutch firmly engaged to transmit high torque.
Thus instead of having more stiff springs for keeping the clutch engaged firmly at high speeds, they are less stiff because of centrifugal forces of weighted levers, so that the driver may not get any strain in operating the clutch.
when the engine speed decreases, the weights fall and the weighted levers do not exert any pressure on the pressure plate and only spring pressure is exerted on the pressure plate to keep the clutch engaged.

Centrifugal clutch is automatic no clutch pedal and driver control. Semi Centrifugal has clutch a clutch pedal to control engagement.
Semi centrifugal clutch is often used in mopeds, go-karts, underbones, chainsaws, mini bikes, lawn mowers, and some paramotors and boats.
