ABSTRACT:
The combustion zone of an internal combustion engine is provided with a catalyst which is incorporated in the combustion zone as a thin layer placed on the internal cylinder walls and/or the top surface of the piston and/or on surfaces of the spark plug which are exposed to the combustion zone of the cylinder for the purpose of cracking the carbon-carbon bonds in the heavier fuel molecules immediately prior to combustion within the combustion zone of the cylinder. The light fuel molecules produced during fuel contact with the catalyst yields a more complete combustion and extraction of the exothermic energy, thereby increasing fuel economy and decreasing the amounts of incomplete combustion products leaving the exhaust. The catalysts for use in the present invention include acidic metal oxide mixtures.
