ABSTRACT:
The present invention provides a method for catalytic aging and a system for catalytic aging. The system modifies the operation of the engine while running in combination with a catalyst, making the engine a programmable gas generator for the catalyst. The present invention allows an operator to alter the operation of the engine by varying the signals to the engine's injectors, thereby altering the exhaust gas of the engine. While the engine is operating under user initiated injector signals, a simulated exhaust gas oxygen signal is provided to the engine control module. This signal results in maintaining the engine in stable operation while operating in an unstable state. In a preferred embodiment additional gases are injected into the exhaust gas being supplied to the catalyst. The system periodically returns all functions to the engine control modules allowing the establishment of new operating parameters for the engine.
