摘要： 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.

摘要： A method for controlling an exhaust aftertreatment system for a vehicle includes: determining, by a controller, whether or not a driving state of the vehicle satisfies a clogging determination condition; estimating, by the controller, a normal temperature of a rear end of a catalytic converter upon determining that the clogging determination condition is satisfied; calculating, by the controller, clogging indexes using an actual temperature of the rear end of the catalytic converter measured by a temperature sensor and the estimated normal temperature; determining, by the controller, whether or not it is necessary to settle clogging of the catalytic converter by comparing the clogging indexes with reference ranges; and executing, by the controller, a clogging settlement mode upon determining that it is necessary to settle clogging of the catalytic converter.

摘要： A method of regenerating a selective catalytic reduction catalyst on a diesel particulate filter (SDPF) includes predicting a reducing agent amount oxidized in the SDPF during regeneration of the SDPF if the regeneration of the SDPF is necessary; calculating a quantity of heat generated from the reducing agent amount oxidized in the SDPF; calculating a temperature change from the generated quantity of heat; calculating a target temperature when regenerating the SDPF; and performing the regeneration according to the target temperature.

摘要： 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.

摘要： A method for controlling a powertrain of a hybrid vehicle includes the following steps performed by a hybrid controller: determining whether an ambient air temperature is lower than a predetermined temperature; driving a motor and operating a heating disc of an electrically heated catalytic converter disposed in an exhaust pipe of an internal combustion engine during a predetermined operating time when an ambient air temperature is lower than a predetermined temperature; supplying ambient air to the heating disc; and varying a flow rate of the ambient air supplied to the heating disc in response to a temperature change of the heating disc.

摘要： A method of purifying exhaust gas may include predicting a slip probability of ammonia (NH3) to a rear end of a selective catalytic reduction on diesel particulate filter (SDPF), comparing the predicted ammonia slip probability with a slip probability of ammonia limiting operation of a low pressure-exhaust gas recirculation (LP-EGR) system, comparing an absorption amount of ammonia with a value obtained by multiplying an ammonia absorption target amount by a minimum target absorption amount ratio when the predicted ammonia slip probability is larger than the slip probability of ammonia limiting operation of the LP-EGR system, limiting the operation of the LP-EGR when the absorption amount of ammonia is not larger than the value obtained by multiplying an ammonia absorption target amount by a minimum target absorption amount ratio, and dosing a urea solution.
