DEVICE AND METHOD FOR MEASURING REAL TIME SOOT OXIDATION RATE OF DIESEL PARTICULATE FILTER USING TEMPERATURE SENSOR, AND REGENERATION CONTROL METHOD OF DIESEL PARTICULATE FILTER USING THE METHOD FOR MEASURING REAL TIME SOOT OXIDATION RATE

摘要

PURPOSE: An apparatus and method for measuring the oxygenation rate of an exhaust using a temperature sensor, and a method for regenerating the diesel particulate filter are provided to accurately measure the residual amount of the exhaust and non-carbon particulates. CONSTITUTION: An apparatus for measuring the oxygenation rate of an exhaust using a temperature sensor comprises a diesel oxidation catalyst (DOC) (3), a first temperature sensor (5a), a second temperature sensor (5b), and a control unit. The diesel oxidation catalyst is installed at the upper part of a particulate filter (4). The first temperature sensor is installed between the diesel oxidation catalyst and particulate filter to measure the temperature of the exhaust gas before the exhaust gas passes through the particulate filter. The second temperature sensor calculates the oxygenation rate of the exhaust using temperature data being measured by the first and second temperature sensors in real time in order to measure the temperature of the exhaust gas.
