| titleOfInvention |
Fuel and lubricant compositions for inhibition or prevention of octane requirement increase |
| abstract |
The prevention or substantial reversal of octane requirement increase in a spark-ignited, internal combustion engine is achieved by introducing, with the combustion intake charge, a fuel and/or lubricant composition containing an octane requirement increase-inhibiting amount of a high surface area, solid acid catalyst having an average particle size in the range of about 0.01 to 10 microns and an average non-volatile surface acidity of about 1 or less, expressed as pKa value, said solid acid catalyst being essentially nonreactive with the fuel or lubricant prior to combustion and chemically and thermally stable under combustion conditions in the engine. |
