ENGINE, AND METHOD FOR PRODUCING ENGINE

摘要

An engine (1A) is provided with a cylinder block (10A) in which a first water jacket (12) is disposed on the periphery of bores (11). A first groove (13) which has a predetermined depth and opens to the deck surface (D) of the cylinder block (10A) is disposed on a predetermined section on the cylinder block (10A), said section being at a location between the bores (11) and the first water jacket (12). A first highly heat conductive material (14) having a higher thermal conductivity than the base material of the cylinder block (10A) is disposed on the first groove (13). The first highly heat conductive material (14) is formed in the first groove (13) so as to expose to the deck surface (D) by supplying a material to the first groove (13) and melting said material by means of laser beams.
