연속가변밸브 작동기구의 제어용 핵심부품 개발에 관한 연구

Recently, CO₂ regulation tightening continues to correspond to a global warming phenomenon. In this study, control core system of Continuously Variable Valve Lift(CVVL) was developed. The system is consists of operating motor, mechanical linkage, position sensor and control unit. The continuous variable valve which can control a valve lift successively at the whole driving territory of an engine when applying a lift (CVVL, continuously variable valve lift) system, it's possible to improve the performance of the engine further and make fuel consumption decrease. Continuous variable valve a lift The aerial control inhaled by the speed of engine revolution is possible by a system, so control to air intake of a throttle valve isn't necessary. This study has developed a driving motor, mechanical link structure, position sensor and cotrol unit. Continuously variable valve lift system is loaded on RIG equipment, the control special quality and operation, the grade and the reliability assessment were put into effect.
