Abstract:
1. A method for using a burner-based automotive exhaust gas simulation system to test an automotive exhaust system component, comprising: providing a burner system having at least a burner for receiving air and fuel having an air-fuel ratio and for combusting fuel to produce simulated engine exhaust; an exhaust line for carrying the exhaust from the burner to the component; and a heat exchanger for cooling the exhaust gas downstream the burner; placing the component in the exhaust line downstream the heat exchanger; using a computerized control system to control the ratio of fuel and air combusted by the burner, and to control the temperature of the exhaust at the input to the component; and using the component to treat the exhaust during specified operating conditions of temperature and air-fuel ratio; exposing the component to vibration during the step of using the component; and evaluating the effect of the vibration on the component.
