Hereinafter, the present invention will be explained with reference to drawings of embodiments. FIG. 5 is a side view of an in-line engine according to an embodiment of the present invention, and FIG. 6 is a sectional view taken along C 1 -C 2 thereof. The line l1 - l2 connecting the axes of the tightening bolts 41 '' and 42 '' of the cylinder head 2'' is the same as the line connecting the axes of the tightening bolts 51 '' and 52 '' of the bearing cap 3''. The cooling water channels 1"c, 1"d, 1"e connecting the water gear rallies 1"a and 1"b are installed to be inclined by θ 1 compared to the conventional one.
is provided so as to be inclined by θ 2 in the direction opposite to the line l 1 -l 2 connecting the axes of the tightening bolts 4 1 ″ and 4 2 ″ than in the past (FIGS. 1 and 2).
