Abstract (en)

[origin: EP1207292A2] Object: In a horizontal opposed type internal combustion engine, to enable rigid support of a middle journal of a crank shaft through rational utilization of first and second case halves constituting a crankcase, and to thereby contribute to a simplification in structure and a reduction in weight. Solving Means: In a horizontal opposed type internal combustion engine in which a crankcase (6) is split at a plane (P) containing the axis line (A) of a crank shaft(1) into first and second case halves (6L, 6R) connected with first and second cylinder blocks (7L, 7R), the first and second case halves (6L, 6R) are provided integrally with first and second journal supporting walls (13Lm, 13Rm) for supporting a middle journal (3m) of the crank shaft (1), the first and second journal supporting walls (13Lm, 13Rm) fronting on cylinder bores (10Lr, 10Rf) of the first and second cylinder blocks (7L, 7R), and the first and second journal supporting walls are coupled by a plurality of first bolts (19L) inserted from the side of the cylinder bore (10Lr) of the first cylinder block(7L)and disposed on both sides of and in proximity to the middle journal (3m). <IMAGE>
