Claim 1

A METHOD FOR DECARBONIZING AN INTERNAL COMBUSTION ENGINE HAVING AN ENGINE BLOCK PROVIDED WITH A PLURALITY OF CYLINDERS, A CYLINDER HEAD, AN OVERHEAD VALVE ASSEMBLY FOR EACH OF SAID CYLINDERS, A PISTON RECIPROCABLY MOUNTED IN EACH CYLINDER, SAID CYLINDERS HAVING SEALING RINGS, SAID VALVE ASSEMBLY HAVING A PLURALITY OF RECIPROCABLE VALVES FOR THE TIMED INTRODUCTION OF A FUEL-AIR MIXTURE INTO THE CYLINDERS AND FOR THE TIMED EXPULSION THEREFROM OF EXHAUST GASES, EACH OF SAID VALVES HAVING AN ELONGATED STEM SLIDABLY MOUNTED IN SAID CYLINDER HEAD AND TERMINATING IN A VALVE HEAD OPERABLE TO ENGAGE A SEAT FORMED IN SAID CYLINDER HEAD A CRANKCASE A PLURALITY OF ROCKER ARMS FOR ACTUATION OF SAID VALVES A COMPARTMENT FOR HOUSING SAID ROCKER ARMS DEFINED IN PART BY A COVER, ONE OR MORE PASSAGES IN SAID ENGINE BLOCK FOR DRAINING OIL FROM SAID ROCKER ARM COMPARTMENT TO SAID CRANK CASE, COMPRISING THE STEPS OF LEVELING THE ROCKER ARM COMPARTMENTS OF THE ENGINE LONGITUDINALLY, PLUGGING SAID PASSAGES, INTRODUCINGA SOLVENT OIL DIRECTLY INTO SAID ROCKER ARM COMPARTMENT, OPERATING THE ENGINE UNDER ITS OWN POWDER FOR A PREDETERMINED PERIOD OF TIME SO THAT THE RECIPROCATING MOVEMENT OF SAID VALVES FORCES THE SOLVENT OIL ALONG THE VALVE STEMS AND INTO CONTACT WITH THE VALVE HEADS AND SEATS AND INTO CONTACT WITH THE CYLINDER WALLS, PISTONS AND PISTON RINGS FOR REMOVAL OF CARBON FROM THE SURFACES THEREOF, AQND EXHAUSTING THE CONTAMINATED SOLVENT OIL WITH THE USED FUEL-AIR MIXTURE.

Claim 2

A METHOD FOR DECARBONIZING AN INTERNAL COMBUSTION ENGINE HAVING AN ENGINE BLOCK PROVIDED WITH A PLURALITY OF CYLINDERS, A CYLINDER HEAD, AN OVERHEAD VALVE ASSEMBLY FOR EACH OF SAID CYLINDERS, A PISTON RECIPROCABLY MOUNTED IN EACH CYLINDER, SAID CYLINDERS HAVING SEALING RINGS, SAID VALVE ASSEMBLY HAVING A PLURALITY OF RECIPROCABLE VALVES FOR THE TIMED INTRODUCTION OF A FUEL-AIR MIXTURE INTO THE CYLINDERS AND FOR THE TIMED EXPULSION THEREFROM OF EXHAUST GASES, EACH OF SAID VALVES HAVING AN ELONGATED STEM SLIDABLY MOUNTED IN SAID CYLINDER HEAD AND TERMINATING IN A VALVE HEAD OPERABLE TO ENGAGE A SEAT FORMED IN SAID CYLINDER HEAD A CRANKCASE A PLURALITY OF ROCKER ARMS FOR ACTUATION OF SAID VALVES A COMPARTMENT FOR HOUSING SAID ROCKER ARMS DEFINED IN PART BY A COVER, ONE OR MORE PASSAGES IN SAID ENGINE BLOCK FOR DRAINING OIL FROM SAID ROCKER ARM COMPARTMENT TO SAID CRANK CASE, COMPRISING THE STEPS OF LEVELING THE ROCKER ARM COMPARTMENTS OF THE ENGINE LONGITUDINALLY, PLUGGING SAID PASSAGES, INTRODUCINGA SOLVENT OIL DIRECTLY INTO SAID ROCKER ARM COMPARTMENT, OPERATING THE ENGINE UNDER ITS OWN POWDER FOR A PREDETERMINED PERIOD OF TIME SO THAT THE RECIPROCATING MOVEMENT OF SAID VALVES FORCES THE SOLVENT OIL ALONG THE VALVE STEMS AND INTO CONTACT WITH THE VALVE HEADS AND SEATS AND INTO CONTACT WITH THE CYLINDER WALLS, PISTONS AND PISTON RINGS FOR REMOVAL OF CARBON FROM THE SURFACES THEREOF, AQND EXHAUSTING THE CONTAMINATED SOLVENT OIL WITH THE USED FUEL-AIR MIXTURE.
