Abstract: An opposed piston engine includes an engine housing, at least one cylinder housing coupled to the engine housing, and at least one cylinder supported by the engine housing and by the cylinder housing along an exterior of the engine housing.

Abstract: An edge connector is provided for a printed circuit board having a mating edge and a plurality of contact pads adjacent the edge. The connector includes an elongated dielectric housing having a board-receiving slot for receiving the mating edge of the printed circuit board. A plurality of spring contact elements are mounted in the housing along at least one side of the slot. The spring contact elements have first spring contact portions extending into the slot for contacting respective ones of the contact pads on the printed circuit board. A surface of the housing at the one side of the slot defines a datum plane beyond which the spring contact portion of at least one of the spring contact elements extends into the slot. Some of the spring contact elements include second spring contact portions formed in a unique arcuate configuration for biasing the printed circuit board against the surface, thereby deflecting the first spring contact portions a predetermined amount.
