20150177746 | METHOD OF CORRECTING CONTROL LOGIC OF SELECTIVE CATALYTIC REDUCTION CATALYST AND EXHAUST SYSTEM USING THE SAME - Disclosed are a method of correcting a control logic of a selective catalytic reduction (SCR) catalyst and an exhaust system. The control logic may be adapted to calculate an injection amount of a reducing agent for the SCR catalyst at the least. The method may include detecting input variables including temperature of the SCR catalyst and exhaust flow rate, discretizing the input variables, standardizing the discretized input variables, determining whether the discretized input variables are within a correction range, and correcting the control logic of the SCR catalyst if the discretized input variables are within the correction range. | 06-25-2015 |
20150176457 | METHOD AND SYSTEM OF DETERMINING SUITABILITY OF CORRECTION FOR CONTROL LOGIC OF SELECTIVE CATALYTIC REDUCTION CATALYST - A method of determining suitability of correction for a control logic of a selective catalytic reduction (SCR) catalyst, may include determining a suitability function of the correction based on a previous error and a current error when the correction has been performed, determining a suitability coefficient based on the suitability function of the correction, determining whether the correction may be suitable based on the number of corrections and the suitability coefficient, and resetting the control logic when the correction may be not suitable. | 06-25-2015 |
20150176456 | METHOD OF DETERMINING CORRECTING LOGIC FOR REACTING MODEL OF SELECTIVE CATALYTIC REDUCTION CATALYST, METHOD OF CORRECTING PARAMETERS OF REACTING MODEL OF SELECTIVE CATALYTIC REDUCTION CATALYST AND EXHAUST SYSTEM USING THE SAME - Disclosed are a method of determining a correcting logic for a reacting model of an SCR catalyst, a method of correcting parameters of the reacting model of the SCR catalyst and an exhaust system to which the methods are applied. The reacting model of the SCR catalyst is defined by m parameters and has n input variables, where m and n are natural numbers with n smaller than m. The reacting model of the SCR catalyst may be adapted to predict nitrogen oxide (NOx) concentration at a downstream of the SCR catalyst at the least. | 06-25-2015 |
20140338319 | HYDRAULIC HYBRID SAFETY SYSTEM - A hydraulic hybrid safety system is provided. The hydraulic hybrid safety system is part of a hydraulic hybrid system that has an over-center bent-axis rotary pump/motor with a yoke, the yoke having a zero yoke angle and a plurality of non-zero yoke angles. The safety system includes a spring that is operable to move the yoke to the zero yoke angle when the hydraulic hybrid system loses electrical power. | 11-20-2014 |
