Claims6
A compressed gas supply in an internal combustion engine, comprising a one-way valve (20) in at least one of the combustion chambers of the engine for bleeding a small proportion of the charge compressed in the combustion chamber into a plenum chamber (30) and a tube (32) communicating at one end with the plenum chamber (30) and having at its other end an outlet (38) from which gases can be supplied at a pressure substantially lower than the pressure within the plenum chamber, characterised in that the tube is a capillary tube (32) that acts as a temperature dependent flow regulator.
