English to French Tech/Engineering Patents (in a patent) ENGINE-DRIVEN WORKING MACHINE

when the rotation speed of the engine (2) is higher than a predetermined clutch-in rotation speed, the centrifugal clutch (6) connects the engine (2) with the actuating part (4) so as to transmit rotations of the engine (2) to the actuating part (4),

in a fast idling state in which the engine (21) is operated while a throttle valve (10) of a carburetor (8) of the engine (2) is maintained in a half-opened position, the controller (18) is operated from starting of the engine (2) in a rotation speed limitation mode in which the engine (2) is prevented from rotating at a rotation speed that is higher than the clutch-in rotation speed,

in the rotation speed limitation mode, the controller (18) prevents the engine (2) from rotating at a rotation speed which is higher than the clutch-in rotation speed by appropriately causing a misfire cycle in the engine (2).
