GASOLINE ADDITIVES FOR REDUCING THE AMOUNT OF INTERNAL COMBUSTION ENGINE DEPOSITS
摘要
<p>Compositions and methods are disclosed for reducing combustion chamber deposits (CCD) and/or intake valve deposits (IVD) in spark ignition internal combustion engines. A succinic acid derivative (SAD) of this invention or a mixture with at least one additional component 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), polyolefin butyrolactam derivatives (BLD), butyrolactam alkoxylates (BLA), tridecanol alkoxylate derivatives (TAD) and polyisobutylene amine (PIBA).</p>
