  • Model for inferring temperature of exhaust gas at an exhaust manifold using temperature measured at entrance of a diesel oxidation catalyst
    Patent number: 8205606
    Abstract: An engine processor (38) processes data for inferring temperature of exhaust gas at an exhaust manifold (18) of an internal combustion engine (10) whose exhaust system (16) contains an after-treatment device (26, 28) for treating exhaust gas and a sensor (30) for providing data for temperature of exhaust gas entering the after-treatment device. The processor processes data from the sensor and other data to infer temperature of exhaust gas at the exhaust manifold by executing an algorithm (FIGS. 3 and 4) that models temperature of exhaust gas at the exhaust manifold as a function of data from the sensor and the other data, including certain constants, certain geometry of the exhaust system, and certain variables related to operation of the engine.
