| 摘要 |
The invention concerns a variable timing device for reciprocating engines with, at least two cam shafts (AC 1 , AC 2 ) comprising, at least an intake valve (A) and at least an exhaust valve (E) actuated by said shafts, and means for shaft angular offset D 1 , D 2 ). The invention is characterised in that at least a common valve (A) is actuated by hydraulic transmission means ( 4, 9, 10 ) adapted to transmit to said valve the movement of at least two cams (A 1 , A 2 ) belonging to the shafts with distinct cams (AC 1 , AC 2 ) capable of being offset relative to each other. The invention also concerns engines comprising said timing system and a timing and turbocharging method capable of using said distribution. |
