A Novel Gasoline Additive Package Removes Induction System Deposits and Reduces Engine Octane Requirement Increase 891298

Today's high technology engines are designed with fast-burn combustion chambers, swirl-generated intake ports, and improved intake manifold designs to achieve high specific power output, improved fuel economy and lower exhaust emissions. Consequently, the engine performance is greatly affected by deposit build up in these critical areas. Deposits may result in cold-start driveability problems, degradation of fuel economy, loss of power, and increase in NOx emissions. Most gasoline marketers have added polymeric additives to control deposits, though these additives have caused Octane Requirement Increase (ORI) higher than normal. Recently, a new type of chemistry has been developed to control induction system deposits and reduced octane requirement increase.
