<p>The crankcase (101) of the engine is formed by at least one module (8) interposed between the two parts (1, 102) which normally constitute the crankcase (100) of a single-cylinder engine, and to which the module is joined to form one unit by means of rods which pass through holes in the module. The crankcase formed in this way has at least two identical and adjacent voids (104, 204) with any necessary transfer ports, formed by pairs of facing and complementary recesses (6, 9 and 7, 10), formed partly (9, 10) in the said module and partly (6, 7) in the end parts of the crankcase. The module is provided at its top with rods (13) which in combination with those (5) of the end parts of the crankcase may be used to fix corresponding cylinders (14, 114), identical to those of single-cylinder engines, on the said voids. The said module (8) may be conveniently designed for the intermediate support of the shaft (200) of the multiple-cylinder engine. <IMAGE></p> |
