<p>An engine, according to the present invention, includes: a cylinder block, in which a plurality of compression chambers are concentrically disposed around a rotation shaft; a plurality of pistons which reciprocates the plurality of compression chambers, respectively, in the vertical direction; and a cam which is penetrated by the rotation chamber in the cylinder block and converts the rotational motion of the pistons to reciprocating motion when the cylinder block rotates, wherein the structure is simple and the size is reduced such that assembly is simple and a mounting space is readily secured. In addition, only one suction section and one exhaust section are provided to a cylinder head regardless of the number of compression chambers. Therefore, the structure of the suction section and the exhaust section is simplified, reducing energy loss.</p> |
