摘要:
An engine structure for a multi-cylinder, opposed-piston engine includes a cylinder block with a plurality of inline cylinders. Each cylinder has ends with an outside diameter and an intermediate portion between the ends of a relatively larger outside diameter than the ends. The cylinder block includes a bearing web structure that positions bearing web elements outside of a plane that longitudinally bisects all of the cylinders. The cylinder block is split into two sections so as to permit cylinder liners to be inserted into and removed from cylinder tunnels in the cylinder block.

A structure of bearing housings of a cylinder block comprises aluminum alloy for constituting the whole cylinder block and a plurality of fiber reinforced metal (FRM) areas. The FRM areas are formed by integrally casting a sheet-like preform containing reinforced metal fibers with aluminum alloy. A plurality of such sheet-like preforms are separately provided in a bearing housing in an axial direction of a crankshaft.

A multi-cylinder internal combustion engine with a vacuum and an exhaust gas system is provided with a feed device for secondary air into the exhaust gas system and with an external exhaust gas return. The lines required for this are integrated into the housing to a substantial extent and are used for feeding secondary air during the warm-up phase as well as for subsequent exhaust gas return.
摘要:
The disclosure illustrates an opposed multicylinder internal combustion engine suitable for aircraft use. The engine is fabricated from a pair of matched crankcase halves which enable die casting for limited production. The matched crankcase halves and rows of cylinder barrels and cylinder heads on opposed sides are secured by bolts which extend the width of the engine. The crankcase halves are mounted together at a series of ribs symmetrically positioned with respect to the midpoint of the crankcase halves. The cylinder barrels are mounted on pads offset from the midpoint so that the opposed barrels are in a staggered relationship on the assembled engine.
