Abstract:
A cylinder block defines a cylinder, in which a piston is reciprocated. The cylinder includes an upper bore, a center bore, and a lower bore arranged in order from proximity to a cylinder head in the axial direction of the cylinder. The inner diameter of the center bore is greater than the inner diameters of the upper bore and the lower bore. The cylinder block defines an upper recess that serves as an upper water jacket surrounding the upper bore and a lower recess that serves as a lower water jacket surrounding the lower bore. The upper recess and the lower recess are spaced apart from each other in the axial direction of the cylinder so as to sandwich a spacer.
