Abstract: A modified crank tool of a variable geometry turbocharger and a method for compensating for linkage abrasion are provided to obtain constant power by compensating for reduction of engine power caused by variation in a rotation angle of a vane through abrasion of a linkage. A modified crank tool of a variable geometry turbocharger comprises a rack gear(13) formed at an actuator rod of an actuator. A pinion gear(14) is fixed to an internal pin(15) such that the pinion gear engages with the rack gear. A vertical movement of the actuator is transferred to a crank tool through the rack gear and the pinion gear. Since the pinion gear is fixed to the internal pin, the pinion gear is meshed with the rack gear. As the pinion gear rotates, the internal pin rotates, so that displacement of an opening and closing angle of a vane is determined.

Abstract: A swirl control valve device is provided to preventing failure of an engine and damage of a diesel particulate filter by instantaneously and forcibly releasing a twin gear connecting a motor gear with a shaft gear. A swirl control valve device comprises a swirl control valve, a motor gear(10), a shaft gear(50), a twin gear(30) and a shaft gear spring. The swirl control valve raises the combustion efficiency and reduces soot by adjusting flow of air supplied to a combustor. The shaft gear closes the swirl control valve by rotating a shaft on which the swirl control valve is mounted. The twin gear has one end connected with one side of the motor gear to transfer driving force of a motor to the shaft gear. The shaft gear spring returns the shaft gear in an open state. When swirl control valve is fixed in a closed state, a releasing member instantaneously and forcibly releases the twin gear that connects the motor gear with the shaft gear.
