In order to confirm the performance and characteristics of plasma jet ignition quantitatively, combustion tests were carried out by varying the governing parameters of plasma jet ignition. Three plasma cavity sizes of 37, 75, 170 mm3, two orifice diameters of 1 and 2.5 mm, and three discharge energies of 0.3, 1.5, and 6.7 J were tested in two different types of combustion vessels with lean hydrogen-air mixtures at equivalence ratios of 0.3 and 0.4. From a series of tests, the combustion enhancement by the plasma jet ignition is revealed only in the initial stage of combustion. Then a comparing parameter of the performance of plasma jet ignition in its initial stage of combustion is proposed by comparing the pressure diagram of plasma jet ignition and that of conventional single-point center ignition. The performance and the characteristics of plasma jet ignition are revealed quantitatively by the comparing parameter.
