Numerical Investigation of the Combined Influence of Three-Plug Arrangement and Slot Positioning on Wankel Engine Performance

Abstract: A numerical methodology for three-dimensional fluid dynamics and chemical kinetics simulation of the combustion and gas-exchange processes in the Wankel engine was developed and validated. Two approaches of performance enhancement were studied—the addition of a slot in the rear side of the rotor recess, and installation of a third plug in the trailing side of the working chamber, in addition to the two available plugs mounted in the leading side of the baseline engine. The obtained results showed that the sugg… Show more

“…In a peripherally-ported engine like this one, recently Pisnoy and Tartakovsky have shown how revised ignition arrangements and optimization of the rotor flank cutout can affect combustion [18]. They studied a three spark-plug configuration, with two in parallel at the leading position and one in a trailing position and showed that further improvements in combustion (and presumably therefore concomitant reductions in HC emissions), independent of the rotor cooling arrangement, may still be possible.…”
