Abstract

The ignition mechanism of lean mixture by a pulsed jet is investigated. In order to examine the combustion phenomena in the cavity of the pulsed jet igniter, a transparent cavity was made and schlieren photographs were taken. The electric characteristics in a jet issuing from the orifice of the pulsed jet igniter were measured using an electrostatic probe. The schlieren photographs revealed the combustion process in the cavity, and the signals from the electrostatic probe showed that the ejection duration of the chemically active products of incomplete combustion in the cavity was very short. This duration is governed by the period of spark discharge, and the re-establishment of combustion in the jet is confirmed.
