    Patent number: 7412335
    Abstract: A burner-based system for producing exhaust that simulates the exhaust produced by a production type internal combustion engine. The system is computer controlled so that parameters such as the composition of the exhaust, its rate of flow, and its temperature can be specified. This permits various engine operating conditions to be simulated. An emissions control device can be installed to receive the exhaust, and to thereby undergo rigorous testing. Various tests for durability can be performed.
