ABSTRACT:
A two cycle crankcase compression diesel engine having a supplemental exhaust port system that is formed in a straight line perpendicular to the cylinder bores and which intersects the main exhaust ports. An exhaust control valve arrangement is provided for controlling the flow through the supplemental exhaust ports to reduce the compression ratio under high load, high speed running conditions. The supplemental exhaust control valves comprise a plurality of individual valves each contained within a common bore extending through the cylinder and interconnected by connecting members that permit axial and circumferential misalignment so as to accommodate for distortion and avoid sticking of the valves.
