  • Patent number: 6821932
    Abstract: The present invention relates to an apparatus and method for delivering molybdenum from a lubricant source into a fuel combustion system or to the exhaust therefrom. By the present invention, molybdenum from the lubricant or the fuel will interact with phosphorus, sulfur, and/or lead from the combustion products. In this manner, the molybdenum scavenges or inactivates harmful materials which have migrated into the fuel or combustion products, and which can otherwise poison catalytic converters, sensors and/or automotive on-board diagnostic devices. The present invention can also lead to improved durability of exhaust after treatment systems.

  • Publication number: 20040010966
    Abstract: A method for reducing the formation of combustion chamber deposits in an engine using a friction modifier for combustible fuels is provided. The friction modifier is prepared by combining a saturated carboxylic acid and an alkylated or alkoxylated amine. The particular selection of friction modifier enables a stable additive concentrate to be formulated providing a significant decrease in CCD without increasing the incidence of IVD deposits in combustion engines running on a fuel modified with the additive concentrate.

  • Publication number: 20030172584
    Abstract: A middle distillate fuel additive comprising the reaction product resulting from the combining of a hydrocarbyl succinic anhydride and a hydroxyamine. The lubricating properties of low sulfur-content middle distillate fuels, such as diesel, jet or bio-diesel fuels, can be significantly improved by inclusion therein of such additive compounds. The use of these middle distillate fuel additives makes it possible to avoid mechanical failure problems, such as fuel pump or injector failure, otherwise caused by inadequate fuel lubricity, while still retaining the environmental benefits of using a low sulfur fuel.

  • Patent number: 5612492
    Abstract: A pressure sensitive paint is coated onto the surface over which a pressure distribution is to be measured, such as in a wind-tunnel test of an aerodynamic body. A pressure sensitive paint is a mixture of a photoluminescent-compatible, oxygen-permeable binder that is a mixture of silanol-terminated polydimethylsiloxane and methyltriacetoxysilane, and a photoluminescent active agent such as tris(4,7-diphenyl-1,10-phenanthroline) ruthenium(II) chloride pentahydrate. The binder and active agent are placed into an appropriate amount of a solvent for the binder and the active agent, such as dichloromethane, and applied to a surface. In testing of the surface such as wind tunnel testing, the active agent quantitatively luminesces responsive to the local external pressure at the surface.
