摘要： There is provided a V-type engine, in which deck cylinder parts of a cylinder block are offset in the same direction as a rotational direction of a crankshaft, and oil separation chambers are provided at an upper portion of the cylinder head displaced to a lower side by the offset. Therefore, an allowance in the axial direction of cylinders may be provided above a cylinder head of the deck cylinder parts on the lower side, and the capacity of the oil separation chambers is increased by the allowance so that the oil separation performance may be improved, while an increase in the total width and total height of an engine block is suppressed.

摘要： A valve gear for an internal combustion engine capable of promptly switching the position of a piston in a rocker arm to thereby change the engine operating condition with a satisfactory response, even in a low rotation region in which an adequate amount of oil discharged from an oil pump cannot be expected. Depending on positions of pistons slidably fitted in low-speed and high-speed cylinder portions provided in an intake driven rocker arm, a low-speed or high-speed drive rocker arm is selectively operated to press a corresponding one of the pistons. The piston in the low-speed cylinder portion switched in a low rotation region is made smaller in diameter than the piston in the high-speed cylinder portion, to be enabled to be promptly switched.

摘要： A variable valve device of the invention has a structure in which, as connecting means for connecting a movable cam 22 located in an outer periphery of an outer camshaft 17a and an inner camshaft 17b located inside the outer camshaft 17a, there are provided a pin-like member 24 that is movably inserted so as to penetrate the movable cam 22, the outer camshaft 17a and the inner camshaft 17b along a diametrical direction of a shaft member 17 that is formed by turnably encasing the inner camshaft 17b in the outer camshaft 17a, and an escape-preventing portion 50 disposed in the end portion of the pin-like member 24. The movable cam 22 and the inner camshaft 17b are thus connected together while preventing large press-fit load and axial force from acting on components.
