PROBLEM TO BE SOLVED: To provide a diesel engine including a frame capable of bearing an increase in a side thrust pressure load without increasing the thickness of a side plate. SOLUTION: This diesel engine 22 includes a base plate part for storing a crankshaft, a frame part 23 having a connecting rod for linking the crankshaft and a guide part for vertically moving a crosshead, and a jacket part for storing a piston connected to the crosshead in a cylinder. The frame part 23 includes beam members 24 comprising steel having an I-shaped cross section, fixed spaced apart from each other, fixed to double partitioning walls 15, 16 for partitioning the cylinder by spot welding. A thin side plate 25 is placed on flange parts of the beam members 24 between the beam members 24 constituting a structural material and fixed thereto by spot welding. An inner pressure load of the cylinder and a side thrust pressure load are received by the beam members 24. COPYRIGHT: (C)2011,JPO&INPIT |
