A dynamic camshaft mounting device for a variable valve lift system is provided to reduce vibration of a camshaft by installing a variable spring unit to a lower portion of a bearing unit. A dynamic camshaft mounting device comprises a variable spring unit(9), a displacement sensor(15), a throttle position sensor(31), a fuel sensor(33), an air flow sensor(35), and an RPM sensor(37). The variable spring unit is interposed between a lower portion of a bearing unit(3) and a cylinder head(5) to vary a spring characteristic according to a control signal from a controller(7). The displacement sensor detects a gap between a lower surface of the bearing unit and an upper surface of the cylinder head and the throttle position sensor detects an opening degree of a throttle valve. The fuel sensor detects an amount of fuel and sends a signal thereof to the controller. The air flow sensor detects the amount of air. |
