    摘要: Diesel fuels containing low concentrations of specific bimetallic or trimetallic fuel-borne catalysts reduce particulates and other emissions without the use of after treatment devices, such as filters or catalysts, e.g., diesel particulate filters (DPF's) or diesel oxidation catalysts (DOC's) in the case of diesel engines. By utilizing a fuel containing a fuel-soluble catalyst comprised of platinum and at least one additional metal comprising cerium and/or iron, production of pollutants of the type generated by incomplete combustion is reduced. Preferred fuel borne catalyst levels will be low, e.g., from 0.05 to 0.5 ppm for platinum and 3 to 8 ppm for cerium and/or iron, thereby providing effective engine out emissions reductions without any aftertreatment device. Performance of lightly catalyzed aftertreatment devices will be improved with the subject invention.

    摘要: Described are a gasoline fuel additive which meets the needs of the art with regard to the problems associated with inactivation of catalytic converters. The fuel additive will comprise platinum, preferably as platinum COD and cerium, preferably in a form dispersible or soluble in gasoline, e.g., cerium octoate, cerium oleate and/or cerium stearate. Dosage rates for the gasoline will provide from about 0.05 to about 2.0 ppm platinum and from about 1 to about 100 ppm cerium. Ratios of the platinum to cerium are preferably within the range of from 1:5 to 1:100.

    摘要: Disclosed is a fuel additive concentrate having a high flash point which is characterized by a viscosity controlled for dosing in a Bernoulli feed device. The concentrate is high temperature stable and is in a form suitable for on-board dosing of fuel which can provide predictable feed rates from a feed device. It comprises a fuel soluble platinum group metal composition and/or a fuel soluble or dispersible cerium composition and/or a fuel soluble or dispersible iron compound and a high flash aromatic solvent. The solvent and the metal composition or compositions are present in relative amounts to provide a FBC concentrate having a flash point (ASTM D93-85) of greater than 140° F. and, a preferred kinematic viscosity within the range of from 7 to 25 centistokes, as measured by ASTM D445 at 105° F.
