機関。 In a reciprocating internal combustion engine that can selectively perform spark ignition and compression ignition using the same internal combustion engine, it is rotatable in conjunction with the crankshaft and moves in the axial direction. A freely movable camshaft, an intake valve cam fixed to the camshaft, an exhaust valve cam fixed to the camshaft at a predetermined distance from the intake valve cam, and the intake valve cam fixed to the camshaft. An intake valve push-up rod for opening and closing the intake valve that moves up and down as the exhaust valve cam rotates, and an exhaust valve push-up rod that moves up and down as the exhaust valve cam rotates to open and close the exhaust valve. The intake valve cam is composed of a spark ignition intake valve cam and a compression ignition intake valve cam, and the exhaust valve cam is composed of a spark ignition exhaust valve cam and a compression ignition exhaust valve cam. During spark ignition, the intake valve push-up rod is moved up and down by the spark-ignition intake valve cam, and the exhaust valve push-up bar is moved up and down by the spark-ignition exhaust valve cam. On the other hand, during compression ignition, the intake valve push-up rod is moved up and down by the compression ignition intake valve cam, and the exhaust valve push-up rod is moved up and down by the compression ignition exhaust valve cam. What is claimed is: 1. A reciprocating internal combustion engine for both spark ignition and compression ignition, comprising a cam moving device configured to do so.
