<p>An internal combustion engine (10) includes an engine housing (12) defining a cylinder (14), and a first and a second gas exchange valve (28, 30) for the cylinder (14), positioned within the engine housing (12). The engine (10) further includes a valve actuating mechanism (32) having a first and a second valve lifter (34, 36) reciprocating within adjacent lifter bores (16, 18) to actuate the first and second gas exchange valves (28, 30). Each of the first and second valve lifters (34, 36) includes an end cap (46, 48) having a misalignment limiting projection (50, 52), limiting rotation of the valve lifter (34, 36) in response to dynamic perturbation.</p> |
