"Fiat was the first auto manufacturer to patent a functional automotive variable valve timing system which included variable lift. Developed by Giovanni Torazza in the late 1960s, the system used hydraulic pressure to vary the fulcrum of the cam followers (US Patent 3,641,988).[3] The hydraulic pressure changed according to engine speed and intake pressure. The typical opening variation was 37%."
O zi buna.

Dar, sa fie inventie bmw daca vrei tu :)
