Abstract: A crank chamber structure for an engine which is designed to reduce vibratory noise, to achieve a reduction in weight and cost, and to improve lubricating performance. The crank chamber structure is positioned between a block-side skirt section and a case-side skirt section respectively provided in a cylinder block and a lower case. The skirt sections are curved outwardly to permit the crank chamber to enclose peripheral loci of connecting rods, and further to permit the crank chamber to be formed by a curvilinear surface whose radius is smaller at successively higher positions above the crankshaft axis, thereby providing a substantially egg-like cross-sectional shape. An opening is provided in the lower case by the case-side skirt section being collapsed to taper toward an oil pan-mating surface of the lower case so as to communicate with the oil pan.
