Patent ID: 7495447

Claim:
A system for testing spark plug durability, comprising: a burner for combusting air and fuel, thereby providing exhaust gas, the burner having a burner tube with a first end for receiving high pressure air input and a second end for outputting the exhaust gas, and the burner further having a fuel injector for injecting the fuel into the burner tube and an igniter for igniting the fuel; a test chamber downstream of and external to the burner, and in fluid communication with the second end of the burner such that it receives the exhaust gas; wherein the test chamber has a plurality of openings, each opening for receiving a spark plug, such that at least the spark plug electrodes extend into the interior of the test chamber; wherein the openings are arranged relative to the interior of the test chamber, such that each spark plug's electrodes are exposed to substantially the same exhaust gas amount and temperature; and an exhaust flow line for exhausting gas from the test chamber.
