DEFINITION

Classification: 60/625

(under the class definition) Apparatus comprising an internal combustion engine with ancillary structure for supplying pressure fluid other than the combustible charge to the expansible chamber of the engine to bring the engine from rest to a speed at which it operates as an internal combustion engine or with an ancillary fluid motor that functions to bring the engine from rest up to operating speed.
