COMPOSITION AND METHOD FOR PREVENTING OR REDUCING ENGINE KNOCK AND PRE-IGNITION IN HIGH COMPRESSION SPARK IGNITION ENGINES |
摘要 |
A lubricant composition for high compression spark ignition engines that contains at least one bismuth-containing compound (e.g., a bismuth salt of a carboxylic acid). A method for preventing or reducing engine knock and pre-ignition in an engine lubricated with a formulated oil. The formulated oil has a composition including at least one bismuth-containing compound (e.g., a bismuth salt of a carboxylic acid). A fuel composition for high compression spark ignition engines that contains at least one bismuth-containing compound (e.g., a bismuth salt of a carboxylic acid). A method for preventing or reducing engine knock and pre-ignition in an engine by using a fuel additive composition in a gasoline fuel composition. The fuel additive composition contains at least one bismuth-containing compound (e.g., a bismuth salt of a carboxylic acid). The lubricating oils of this disclosure are useful as passenger vehicle engine oil (PVEO) products. |

1. A method for preventing or reducing engine knock or pre-ignition in a high compression spark ignition engine lubricated with a lubricating oil by using as the lubricating oil a formulated oil, said formulated oil having a composition comprising from 0.1 to 10 mass % of at least one bismuth-containing compound, based on the total weight of the lubricating oil. |
