Abstract
A main bearing cap construction far a dual-crankshaft, opposed-piston engine has two sets of bolts in a cross-bolted configuration. In a dual-crankshaft opposed-piston engine with at least four main bearings, at least one of the main bearings will have a cap with two sets of bolts in a cross-bolted configuration. In addition to having a cross-bolted configuration, the main bearing cap configuration can have flanges to receive blind bolts and/or additional surface area to interface with the cylinder block.
