A study was conducted using combustion bomb equipment and protocols in a controlled laboratory setting to evaluate the pulsed energy spark plug. Test data shows that pulsed energy plugs deliver a significantly improved spark event creating an enhanced flame kernel with a more consistent combustion process compared to traditional spark plugs. In addition to functioning well in stoichiometric air-fuel mixtures, the pulse energy plug performed better than conventional spark plugs in lean air-fuel mixtures. These findings clearly demonstrate that a Pulstar spark plugs produce a better spark event which results in improved combustion of normal and harder to ignite fuel mixtures.
