Abstract
A vehicle engine adapted to control exhaust gas temperature (EGT) at a catalyst inlet includes an EGT sensor in communication with a system controller and adapted to measure a temperature of exhaust gas at the catalyst inlet, the system controller adapted to compare the measured EGT to a target EGT, and, when the measured EGT is greater than the target EGT, limit gas exchange within a cylinder within the engine during an intake stroke, and increase turbine efficiency of a variable geometry turbocharger of the engine by increasing boost from the variable geometry turbocharger.
