  "textContent": "A cylinder block (10) for an internal combustion engine has a water jacket (18) formed between cylindrically configured cylinder walls (12) and a jacket sidewall (14). The cylinder walls (12) is arranged to slideably retain pistons therein. The jacket sidewall (14) is disposed around an external periphery of the cylinder walls (12). A pair of external block walls (50 and 51) is provided on longitudinal sides of the cylinder block (10) to extend almost an entire longitudinal length of the cylinder block (10). The external block walls (50 and 51) are spaced apart from the jacket sidewall (14) in a transverse direction to form gaps therebetween. The top end portions of the external block walls (50 and 51) constitute an external flange portion (56) of a top deck (20) of the cylinder block (10). Thus, the rigidity of the top deck (20) of the cylinder block (10) is improved, and the sealing between the cylinder block (10) and a cylinder head via a head gasket is improved.",
