Title: Low emissions diesel fuel

Abstract

A method and matter of composition for controlling NO{sub x} emissions from existing diesel engines. The method is achieved by adding a small amount of material to the diesel fuel to decrease the amount of NO{sub x} produced during combustion. Specifically, small amounts, less than about 1%, of urea or a triazine compound (methylol melamines) are added to diesel fuel. Because urea and triazine compounds are generally insoluble in diesel fuel, microemulsion technology is used to suspend or dissolve the urea or triazine compound in the diesel fuel. A typical fuel formulation includes 5% t-butyl alcohol, 4.5% water, 0.5% urea or triazine compound, 9% oleic acid, and 1% ethanolamine. The subject invention provides improved emissions in heavy diesel engines without the need for major modifications.

  • A burner for use in the emissions system of a lean burn internal combustion engine. The burner has a special burner head that enhances atomization of the burner fuel. Its combustion chamber is designed to be submersed in the engine exhaust line so that engine exhaust flows over the outer surface of the combustion chamber, thereby providing efficient heat transfer.

  • Addition of 0.1 to 1.5 percent by weight of wax oxidates to a diesel fuel is found to reduce the amount of soot and invisible particles produced when the fuel is used in a diesel engine. The wax oxidates act synergistically with fuel-soluble organometallic compounds such as alkyl cyclopentadienyl manganese tricarbonyl complex salts in reducing particulates. The wax oxidates used have a ratio of neutralization number to saponification number below about 0.40 and a saybolt universal viscosity at 210* F. Higher than 1600.
  • This patent describes a method of reducing emissions from or increasing the utilizable energy of diesel fuel for powering internal combustion engines. It comprises: admixing with diesel fuel a fuel soluble organo-metallic fuel additive composition in an amount effective to supply from 0.01 to 1.0 parts per million of platinum per part of fuel. The composition comprising a compound having the general formula XPtR{sub 1}R{sub 2}, wherein X is a ligand containing at least one unsaturated carbon-to-carbon bond with an olefinic, acetylenic or aromatic pi bond configuration and R{sub 1} and R2 are, independently, benzyl, phenyl, nitrobenzyl or alkyl havingmore » from 1-10 carbons.« less
  • This patent describes a process for producing a diesel-fuel/water emulsion for a diesel engine comprising: supplying different quantitative proportions of water and diesel fuel as a function of the operating condition of the engine, the supplying including leading the water and diesel fuel quantities separately to an intake side of an injection pump; mixing the quantitative proportions in a pump cylinder; storing temporarily a non-injected highly pressurized excess quantity of mixture in a constant volume accumulator; and providing the excess quantity to the injection pump during a subsequent intake stroke.
