Abstract
An engine processor () processes data for inferring temperature of exhaust gas at an exhaust manifold () of an internal combustion engine () whose exhaust system () contains an after-treatment device () for treating exhaust gas and a sensor () 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.and) 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.
