Abstract: An engine block for an opposed-piston engine includes a first center section and a second center section. The first center section defines a first cylinder half bore having a first longitudinal axis and a first plurality of fastener bores. The second center section defines a second cylinder half bore having a second longitudinal axis and a second plurality of fastener bores that extend from a first end thereof to a second end thereof. The second center section is configured to abut the first center section such that: the first and second cylinder half bores are in fluid communication with one another to collectively form a single cylinder; the first and second longitudinal axes are offset from one another; and the first and second pluralities of fastener bores are aligned with one another for receiving a first plurality of fasteners to join the first and second center sections to one another.

Abstract: An opposed-piston engine includes an engine block, at least two intake valves, and at least two exhaust valves. The engine block includes a first center section and a second center section. The first center section defines a first cylinder half bore having a first longitudinal axis and a first open end. The second center section defines a second cylinder half bore having a second longitudinal axis and a second open end. The second longitudinal axis is offset from the first longitudinal axis. The first and second open ends overlap to form and opening therebetween that places the first and second cylinder half bores in fluid communication with one another to form a single cylinder. The intake valves are arranged at the first open end of the first cylinder half bore. The exhaust valves are arranged at the second open end of the second cylinder half bore.
