Title:
QUATERNARY AMMONIUM SALT DETERGENTS FOR USE IN FUELS
Document Type and Number:
Japanese Patent JP2014221918
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide optimal engine operation, that is, increased fuel economy, better vehicle drivability, reduced emissions and less engine maintenance by reducing, minimizing and controlling deposit formation.SOLUTION: There is provided a quaternary ammonium salt detergent made from the reaction product of the reaction of (a) a hydrocarbyl substituted acylating agent and a compound having an oxygen or nitrogen atom capable of condensing with the acylating agent and further having a tertiary amino group and (b) a quaternizing agent suitable for converting the tertiary amino group to a quaternary nitrogen. Also provided is the use of such quaternary ammonium salt detergents in a fuel composition to reduce intake valve deposits. Compositions and methods of the present invention minimize, reduce and control deposit formation in an engine, thereby reducing fuel consumption, promoting drivability, reducing vehicle maintenance, and reducing emissions so as to enable optimal engine operation.
