Title: A fuel injection system and method of operation for a gaseous fuelled engine with liquid pilot fuel ignition
Inventor: MARK RANDALL T
IPC: F02D19/10
Filed: 2003-09-26
Granted: 2005-05-24
Abstract: A pilot fuel injection valve is provided that is mountable in a cylinder head of an engine and is operable to inject a liquid pilot fuel directly into a combustion chamber. The pilot fuel injection valve comprises a cooling system to keep the pilot fuel at a temperature that is lower than the lowest initial boiling point for the pilot fuel that occurs inside the fuel injection valve. The pilot fuel injection valve further comprises a thermally insulated nozzle so that it's outer surface is not cooled by the cooler cylinder head and the cooler pilot fuel held inside the fuel injection valve whereby the nozzle's outer surface can be heated to a temperature that is not significantly lower than the final boiling point of the pilot fuel so that a significant amount of pilot fuel does not condense on the nozzle surface during engine operation. When a gaseous fuel injection valve also has a nozzle disposed inside the combustion chamber it too can be thermally insulated to allow it to maintain a surface temperature during engine operation that is not significantly lower than the final boiling point of the pilot fuel. The method cools the pilot fuel inside the pilot fuel injection valve to prevent or reduce the partial vaporization of pilot fuel inside the nozzle orifices and in other parts of the fuel injection valve. The method further comprises thermally insulating the nozzle so that when the engine is running, the surfaces that come into contact with pilot fuel within the combustion chamber maintain a surface temperature that is not significantly lower than the final boiling point of the pilot fuel.

Granted: 2010-07-27
Abstract: Biosensor system and method for the electrochemical determination of an analyte in a sample. An analyte reactant is mixed with the sample to form a reaction liquid which is contacted to electrodes for measurement of an analyte detection current. The analyte detection current is characteristic of the analyte concentration in the sample by virtue of a reaction sequence comprising an analyte specific reaction taking place in the reaction liquid and an electrode reaction including transfer of electrons through an electrode surface. A plurality of values of a curve of the analyte detection current versus time is measured and the analyte concentration is derived therefrom by means of an evaluation algorithm. Fast results of high accuracy are achieved in that the DC-voltage is applied to the electrodes during the analyte-specific reaction whereby the analyte-specific reaction and the electrode reaction take place simultaneously resulting in an analyte detection current versus time curve which comprises a section in which the current rises versus time and the analyte detection current is measured at at least two points of time in the rising section and the values of the analyte detection current resulting from said at least two measurements are used in the evaluation algorithm for temperature error compensation.
