Abstract
An engine consumes fuel and air to generate an exhaust gas stream. An exhaust system channels the exhaust gas stream from the engine to a tailpipe. An aftertreatment system is included in the exhaust system and includes a catalyst. A transmission system is coupled with the engine. The transmission system includes a transmission and a torque converter coupled with the transmission through a shaft. A lock is included in the transmission system to selectively prevent rotation of the shaft to increase a load on the engine by the torque converter.
