Abstract
A control system for an internal combustion engine is provided, and includes an exhaust gas conduit, an oxidization catalyst ('OC') device, a temperature sensor, an intake mass air flow sensor, an engine air intake mechanism, and a control module. The exhaust gas conduit is in fluid communication with, and is configured to receive an exhaust gas. The OC device is in fluid communication with the exhaust gas conduit. The OC device has an OC light-off temperature. The OC device is selectively activated to the light-off temperature to induce oxidization of the exhaust gas. The temperature sensor is situated in the exhaust stream upstream of the OC device. The temperature sensor monitors an exhaust gas temperature. The intake mass air flow sensor measures an air mass entering the internal combustion engine. The engine air intake mechanism is selectively activated to modulate the air mass entering the internal combustion engine.
