ABSTRACT:
A cylinder block of an internal combustion engine, comprises an integrally formed metallic main body including a cylinder section and bearing bulks and a part of a water jacket. First and second side cover members are secured respectively to the opposite side surfaces of the main body so as to maintain a fluid-tight seal therebetween, each side cover member defining thereinside a part of said water jacket and including a skirt section. The side cover members are made of a non-metallic material which is light in weight and high in damping capacity, thereby effectively damping the engine vibration transmitted to the side cover members to prevent the skirt section of the side cover members from emitting noise.
