Abstract:
1. A method of enhancing the operation of a diesel fuel combustion system, the method comprising: supplying a diesel fuel to a diesel fuel combustion chamber in a diesel fuel combustion system, wherein the diesel fuel comprises an additive that includes a manganese-containing compound, wherein the manganese-containing compound is an organometallic compound selected from the group consisting of alcohols, aldehydes, ketones, esters, anhydrides, sulfonates, phosphonates, chelates, phenates, crown ethers, naphthenates, carboxylic acids, amides, acetyl acetonates and mixtures thereof; 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 an engine oil and the engine oil has at least 3% mass, soot loading; whereby the diesel fuel combustion system performance is enhanced wherein the enhancement is selected from the group consisting of increased diesel engine lubricating oil life, reduced engine wear, and reduced fuel consumption.
