Gasoline additives such as butyrolactam for reducing the amount of internal combustion engine intake valve deposits and combustion chamber deposits |
摘要 |
Compositions and methods are disclosed for reducing combustion chamber deposits (CCD) and/or intake valve deposits (IVD) in spark ignition internal combustion engines. A butyrolactam alkoxylate (BLA) and/or a butyrolactam derivative (BLD) of this invention or a mixture with at least one additional compound of this invention is added to a liquid hydrocarbon or liquid hydrocarbon-oxygenate gasoline each in an amount of about 0.0005-0.5 wt % of the gasoline. Preferably the gasoline is unleaded. The preferred additional components include polyethers (PE) and polyisobutylene amine (PIBA).
