Claims (2)
- 적어도 하나 이상의 실린더(2)와 상기 실린더(2)내를 왕복운동하는 피스톤(4)이 구비하고, 흡입공기를 개폐하는 흡기밸브(20)와 배기가스를 개폐하는 배기밸브(30)가 구비된 엔진에 있어서, 상기 흡기밸브(20)와 배기밸브(30)의 스템엔드(21)에 작동로드(41)로 연결되며, 전기적신호를 기계적 운동으로 변환하여 상기 흡기밸브(20)와 배기밸브(30)를 전후진 이동시키도록 압전소자로 이루어진 두 개의 고정된 압전액튜에이터(40)와, 상기 압전액튜에이터(40)에 전기신호를 공급하는 전기신호발생수단(ES)으로 이루어진 것을 특징으로 하는 압전액튜에이터를 이용한 엔진의 흡/배기 밸브 개폐장치.
- 제1항에 있어서, 상기 전기신호발생수단(ES)은 엔진의 부하조건에 따라 크랭크샤프트위치센서(CPS)와 스로틀밸브위치센서(TPS)로부터 감지된 신호를 내장된 엔진제어방식에 따라 상기 전기신호발생수단(ES)에 인가하여 상기 압전액튜에이터(40)의 작동을 제어함으로써, 상기 흡기밸브와 배기밸브의 개폐를 제어하도록 하는 전자제어유니트(ECU)를 포함하는 것을 특징으로 하는 압전액튜에이터를 이용한 엔진의 흡/배기 밸브 개폐장치.
