20100326183 | APPARATUS AND METHOD FOR TESTING A COMPRESSOR - A test device for a compressor has a valve and ducting connected to the valve. A flow nozzle connected to the ducting has a corresponding coefficient of flow. A pressure sensor connected to the flow nozzle measures a pressure of a working fluid, and a flow rate of the working fluid is calculated using the pressure and the coefficient of flow. A method for testing a compressor includes operating the compressor at a first power level, measuring a flow rate of a working fluid at the first power level, adjusting a pressure of the working fluid to equal a first predetermined pressure, and measuring operating parameters of the compressor at the first power level. The method also includes adjusting the pressure of the working fluid to equal a second predetermined pressure and measuring operating parameters of the compressor at the first power level with the pressure of the working fluid at the second predetermined pressure. | 12-30-2010 |
20120058013 | MODEL BASED TEMPERING AIR CONTROL AND ENHANCEMENT OF EXHAUST FOR SELECT CATALYTIC REDUCTION - A method and system for controlling a temperature of an exhaust gas being introduced to a catalyst is provided. Using an adjustable flow controller, an adjustable amount of tempering fluid is provided to the exhaust gas prior to the exhaust gas proceeding to the catalyst. A sensor senses a parameter indicative of a temperature of the exhaust gas being introduced to the catalyst. A computer processor uses a relationship to relate the parameter to an adjustment of the adjustable flow controller that will adjust the amount of tempering fluid provided to the exhaust gas and change the temperature of the exhaust gas being introduced to the catalyst toward a target temperature. Adjustment of the adjustable flow controller is initiated by the computer processor to change the flow of the tempering fluid, and the relationship between the parameter and the adjustment of the adjustable flow controller is updated. | 03-08-2012 |
