Abstract
A valve disabling device for use in an internal combustion engine having inlet valve means, exhaust valve means, at least one of which comprises a plurality of valves. Disabling means selectively holds the at least one of the inlet valve means and the exhaust valve means in a first state wherein part of the valves thereof are inoperative, and in a second state wherein all the valves thereof are operative for alternate closing and opening actions. Transmission state detecting means detects whether power transmission means of the engine is in a connected state wherein power transmission between the engine output shaft and a load on the engine is allowed, and in a disconnected state wherein the power transmission is inhibited. Control means is responsive to an output from the detecting means to cause the disabling means to hold the at least one of the inlet valve means and the exhaust valve means in the first state when the power transmission means in the disconnected state, irrespective of the rotational speed of the engine.
