Abstract
An in-line opposed cylinder engine constructed of a pair of half blocks which when combined form a pair of spaced cylinder heads and an intermediate crankcase and in which the cylinder heads and the intermediate crankcase are tied together by a plurality of spaced elongated through bolts which extend through the cylinder heads and through the half blocks. Each cylinder head is integral with the remainder of the half block and is preferably of a composite construction with a core of steel or the like which forms the cylinder bore, the firing deck, the exhaust ports and the valve guide as well as the main bearing supports. A matrix structure of lighter material such as aluminum is cast around the core and forms the induction air passages to the intake ports, the coolant passages, oil passages, and the main bearing bosses.
