    摘要： A valve driving device comprising: a tappet assembly 3 adapted to slide in a tappet guide hole 4 to drive a valve 5 and including a high-speed center tappet 31 and low-speed side tappet 32; and a high-speed center cam 21 and a low-speed side cam 22 (23) provided corresponding to the center tappet 31 and the side tappet 32. A depression 21 a is formed which is depressed from a base circle to roughly the same profile as a shaft section of the camshaft 2 so that the cam portion over a predetermined angle range where a cam nose section is not formed in the centrally located center cam 21 is smaller than the base circles of the outside located side cams 22 (23) in profile.

    摘要： In an air intake system for a multi-cylinder in line engine (2) mounted transversely in an engine compartment (1), intake branch pipes of an intake manifold (4,9) extended rearward of the vehicle over the cylinder head cover (3) from intake ports formed in the vehicle front side face of the engine are respectively offset frontward of the engine against spark plug units (31) projecting upward from the cylinder head cover (3), and at least a part of each intake branch pipe (41,91) overlaps vertically when viewing the engine form the rear side. An air cleaner unit (6,10) is arranged above a transmission (2) on the rear side of the engine (2).
