Abstract
A two stroke engine (10) has an exhaust port (16) extending from a side wall of a cylinder (12). A plate valve (26) is movable to an extended position where is the plate valve blocks the upper edge (54) of the exhaust port 16 to effectively retard the opening of the exhaust valve and retractable to a second position which provides the entire axial extent of the exhaust port (16) to be openable with respect to the cylinder. The position of the plate valve (26) is controlled by a diaphragm bladder (46) which is responsive to pressure in the intake system (19) that is in communication with the bladder (46) via an inlet passage (48).
