WIPO Patent Application WO/2012/086131
Kind Code:
A1
Abstract:
In the present invention, a valve gear (50A) operates intake valves (53) of a plurality of cylinders (C), and is provided with a drive camshaft (24) that moves in response to the rotation of a crankshaft (26) of an engine (E); a driven member (64) that is driven by a drive cam (24a) of the drive camshaft (24); an oscillating member (61) that oscillates by interlocking with the driven member (64) and that causes the intake valves (53) to reciprocate; and a valve gear case (100) that houses the camshaft (24), the driven member (64) and the oscillating member (61) together with a control shaft (60). The valve gear case (100) is overlapped by and fastened to the intake side of cylinder heads (20) from above, and is provided with two longitudinal-direction end wall parts, inter-cylinder wall parts, and connection wall parts that connect these parts. This configuration enables easy and accurate control of variation in valve lift across the plurality of cylinders (C) in the valve gear system of the engine (E).
