Patent ID: 7175422

Claim:
A burner-based system for generating exhaust gas that simulates exhaust gas from an internal combustion engine, comprising: a combustor in fluid communication with an air supplier, a fuel supplier for delivering fuel to the combustor, wherein the combustor combusts air and the fuel to generate a flow of exhaust gas into a main exhaust flow line; a volatilized lubricant supplier for delivering a flow of volatilized lubricant into the main exhaust flow line downstream the combustor; wherein the volatized lubricant supplier comprises: an exhaust gas pull line connected to and in fluid communication with the main exhaust line for diverting a portion of exhaust gas from the main exhaust line; a pressurized gas input line in fluid communication with the exhaust gas pull line for forming a mixture of exhaust gas and pressurized gas; a reservoir configured for storing a volume of the lubricant; a probe within the reservoir, said probe configured for receiving and for injecting said mixture of exhaust gas and pressurized gas into lubricant within the reservoir thereby volatilizing the stored lubricant; a first end of a volatilized lubricant delivery line connected to and in fluid communication with volatilized lubricant within the reservoir; and a nozzle connected to and in fluid communication between said volatilized lubricant delivery line and an interior of the main exhaust line for delivering the volatilized lubricant into the main exhaust line at a point downstream the exhaust gas pull line.
