Patent number: 6763807Abstract: A method and apparatus for controlling a fuel injector assembly of an internal combustion engine during cold operation thereof is disclosed. If a combustion-absent condition is detected in one or more of the cylinders associated with the engine, an engine control module cuts out the affected cylinders thereby preventing additional fuel from being delivered to the cylinders for a predetermined period of time, such as 4-5 seconds. During the period of time in which the cylinders are cut out, the pistons in the remaining cylinders associated with the engine continue to operate thereby heating the engine block. After the predetermined period of time, fuel is again injected into the cylinders if a combustion-present condition is detected therein.Type: GrantFiled: November 28, 1997Date of Patent: July 20, 2004Assignee: Clean Fuel Technology, Inc.Inventors: James C. Gilles, Andrew Rockwell

Patent number: 6607566Abstract: 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.Type: GrantFiled: July 1, 1998Date of Patent: August 19, 2003Assignee: Clean Fuel Technology, Inc.Inventors: Gerald N.
