Method of enhancing the operation of diesel fuel combustion systems

Abstract

A method of enhancing the operation of diesel fuel combustion systems in a combustion system includes supplying a fuel and additive that includes a manganese compound to a diesel fuel combustion system. The fuel is then combusted in the combustion chamber to produce at least one byproduct including the manganese compound. The manganese compound is supplied in an amount effective to complex with the combustion byproduct. The diesel fuel combustion system operation is enhanced by improving the attributes of lubricating oil loaded with the combustion byproduct soot particles.

       17 . A method of enhancing the operation of a diesel fuel combustion system, the method comprising: 
 supplying a diesel fuel comprising an additive that includes a manganese-containing compound to a diesel fuel combustion chamber in a diesel fuel combustion system;    combusting the fuel in the combustion chamber to produce at least one byproduct comprising the manganese-containing compound;    the manganese-containing compound being supplied in an amount effective to complex with the at least one combustion byproduct;    wherein the diesel fuel combustion system comprises one or more of the following components:    exhaust gas recirculation systems, hydraulically-activated electronically-controlled unit injectors; elevated mean fuel injection pressure and injection rate shaping capable systems; variable valve actuation systems; homogenous charge compression ignition systems; and low friction coatings on engine surfaces. 
 whereby the diesel fuel combustion system performance is enhanced wherein the enhancement is selected from the group consisting of increased diesel engine lubrication oil life, reduced engine wer, and reduced fuel consumption.
