VALVE GEAR FOR MULTI-CYLINDER INTERNAL COMBUSTION ENGINE

Title:

VALVE GEAR FOR MULTI-CYLINDER INTERNAL COMBUSTION ENGINE

Document Type and Number:

WIPO Patent Application WO/2005/119019

Kind Code:

A1

Abstract:

A valve gear (10), wherein a rotating motion outputted from valve drive sources is converted into a linear motion by cam mechanisms (13) for cylinders installed at the plurality of cylinders (2) and the valves (3) of the cylinders are drivingly opened and closed by utilizing the linear motion. The valve gear comprises electric motors (11, 12) as the valve drive sources used for cylinder groups formed of at least two cylinders in which valve opening periods are not overlapped with each other and transmission mechanisms (14, 15) transmitting the rotations of the electric motors (11, 12) to the cams (16) of the cam mechanisms (13) for the cylinder groups.
