Abstract
A method and system for evaluating the durability of spark plugs. A test system simulates the pressure, temperature, and exhaust flow of an internal combustion engine, and has a test chamber in which these simulated conditions exist. A number of spark plugs are installed in the test chamber and are cycled through a desired ignition cycle. The test chamber temperature and pressure may be precisely controlled, as well as the duty cycle of spark events.
