Abstract: Aspects of the disclosure include a system for controlling an exhaust gas communicated from an engine system to a turbine component of a turbocharger system. The system can include an engine having an operational speed; a turbocharger system including a turbine component, the exhaust gas being output from the engine in an exhaust line; a controller in communication with the engine; and a sensor disposed in the exhaust line being in communication with the controller, the system operating according to the following method: measuring the first temperature of the exhaust gas, determining if the measured first temperature of the exhaust gas is within a temperature safety window of the system; calculating an engine speed of the engine; and adjusting an engine speed setpoint and speed of the engine based on the measured first temperature and the calculated engine speed.

Abstract: A passive mid bed air injection apparatus for an engine includes a three way catalyst positioned in an exhaust stream of the engine. The three way catalyst reduces NOx, CO and HC from the exhaust stream. The three way catalyst includes an ammonia slip catalyst positioned in the exhaust stream of the engine. The ammonia slip catalyst is positioned downstream from the three way catalyst and oxidizes NH3 and CO from the exhaust stream. The three way catalyst includes an oxygen input disposed between the three way catalyst and the ammonia slip catalyst such that the oxygen input delivers air downstream from the three way catalyst and upstream from the ammonia slip catalyst. The oxygen input receives the air from a charged side of a forced induction device and delivers the air to the exhaust stream entering the ammonia slip catalyst. An associated method also provided.
