    摘要： The present method for producing a high stability, low emission, invert fuel emulsion composition comprises blending additives having a surfactant package with a hydrocarbon petroleum distillate fuel in an in-line blending station to create a composition. The surfactant package includes a primary surfactant, a block copolymer, and a polymeric dispersant, and the hydrocarbon petroleum distillate fuel is a continuous phase of the emulsion. The method also comprises blending purified water with the composition in a second in-line blending station to produce a second composition and aging the second composition in a reservoir to produce an aged composition and passing the aged composition through a shear pump to a storage tank.

    摘要： An improved method for producing highly stabile aqueous fuel emulsions. The method provides for selectively combining prescribed quantities of diesel fuel, purified water, alcohol, and an additive package and emulsifying the fuel mixture using a high shear mixer. The optimum viscosity and stability in the aqueous fuel emulsion is achieved by bypassing a selected quantity of the fuel emulsion around the high shear mixing device such that the final fuel emulsion includes a bi-modal droplet size distribution having droplet sizes less than about 15 microns in size. Additional stability and performance features of the aqueous fuel emulsion are attributed to the contents of the additive package that includes a combination of surfactants, lubricity additive, cetane improvers, citric acid, and methanol wherein each of the various additives may perform multiple functions.

    摘要： The present invention is an apparatus for controlling a variable geometry turbocharger (VGT) in closed loop and open loop modes, and a switching mechanism for determining whether open loop or closed loop control laws should be used. In the closed loop mode, a correction factor, obtained from a pressure correction map based on engine speed and atmospheric pressure, is subtracted from the desired boost pressure to prevent overspeed of the turbocharger at lower atmospheric pressures. The actual boost pressure is then compared to the desired boost pressure after correction to obtain a boost pressure error signal. The boost pressure error signal is used as an input to a proportional integral differential control law that responsively produces a desired VGT vane position. A minimum limit on the desired VGT vane position is based on engine speed and fuel quantity, whereas a maximum allowable vane position may be a predetermined constant or function. A linearization map is used to obtain a VGT current signal that is transmitted to an actuator for moving the vane position.

    摘要： A method of operating a diesel engine which overcomes problems encountered during use of a low cetane fuel with long ignition delays is disclosed. The method provides for a staged injection of an emulsified diesel fuel into the combustion chamber of the diesel engine. In particular, the method includes the steps of (A) injecting a pilot volume of an emulsified diesel fuel into a combustion chamber of the diesel engine, wherein the emulsified diesel fuel includes water and diesel fuel, (B) compressing the pilot volume of the emulsified diesel fuel within the combustion chamber during a compression stroke of the diesel engine, and (C) injecting a main volume of the emulsified diesel fuel into the combustion chamber of the diesel engine, whereby heat generated by compression of the pilot volume of the emulsified diesel fuel causes the pilot volume of the emulsified diesel fuel to combust so as to ignite the main volume of the emulsified diesel fuel.

    摘要： Past exhaust emission control systems have failed to cool the exhaust gas prior to mixing with the intake air. The present exhaust gas recirculation system cools a flow of exhaust gas with a common coolant being used to cool an engine prior to mixing the flow of exhaust gas with a flow of intake air. The present exhaust gas recirculation system includes a control system for monitoring an operating parameter of an engine. The control system interprets a signal sensing the operating parameter within a controller and the controller causes an exhaust valve regulator to move between an open position and a closed position. Additionally, a plurality of paths or maps, for example, one being a normal coolant temperature strategy and another being a high coolant temperature strategy is used. In the normal coolant temperature strategy, with the exhaust valve regulator in the open position the supply of fuel to the engine would be advanced. And, in the high coolant temperature strategy, with the exhaust valve regulator in the closed position the supply of fuel to the engine would be retarded. Thus, the emissions emitted from the engine are maintained within a preestablished parameter.
