THE STUDY OF ELECTRICAL PARAMETERS AND THE EXHAUST GAS ANALYSIS FOR A DOUBLE SPARK PLUG
Journal Title: ANALELE UNIVERSITATII DIN CRAIOVA - Seria Inginerie electrica - Year 2011, Vol 35, Issue 35
Abstract
The spark produced by a classical spark-plug does not always assure a fast and complete combustion of an air/fuel mixture into the combustion chamber of a thermal engine. This is the reason why we have done a long series of studies on this subject and a new type of spark plug with three electrodes has been proposed, using two different simultaneous electrical discharges generated by a high voltage power supply. The new type of spark plug should produce a larger and more homogeneous volume of plasma into the engine’s combustion chamber that can assure a faster and complete combustion of the air/fuel mixture. To validate the functionality of the proposed ignition system physical, mechanical, electrical and chemical analysis have been done in order to reveal its benefits comparing with a classical ignition system. In this paper we present a comparison between the electrical parameters, respectively the exhaust gas parameters, when using in a single cylinder engine a classical spark plug and a double spark plug. The electrical parameters of the discharges have been measured in air, at atmospheric pressure and temperature and also when the spark plug was mounted into the cylinder heads. The exhaust gases were analyzed using a ROTRONICS CMR101 air/fuel acquisition system that allows the measurement of the oxygen ratio in the exhaust gas of the thermal engines.
