Patent ID: 7669562

Claim:
A multi-cylinder engine with a cylinder pausing function, said engine comprising: a cylinder block having a plurality of cylinders formed therein; a cylinder head attached to an upper portion of the cylinder block; a cylinder head cover attached to an upper portion of the cylinder head, in which a valve chamber is formed between the cylinder head and the cylinder head cover, an intake valve and an exhaust valve slidably disposed in the cylinder head for each of the cylinders; a valve-actuating mechanism accommodated in the valve chamber for selectively opening and closing the intake and exhaust valves; a hydraulically operated valve-pausing mechanism for selectively suspending operation of at least one of the intake valve and the exhaust valve of one or more of the cylinders, depending on an operation state of the engine, such that the at least one of the intake valve and the exhaust valve is temporarily held in a closed state in the valve-actuating mechanism, and a hydraulic-pressure control device disposed in the engine for controlling hydraulic pressure supplied to the hydraulically-operated valve-pausing mechanism, wherein a recess portion is formed in an external surface of at least one of the cylinder head and the head cover, and the hydraulic-pressure control device is disposed on the cylinder head or the head cover such that at least a part of the hydraulic-pressure control device is accommodated in the recess portion.
