Further Investigations into the Benefits and Challenges of Eliminating Port Overlap in Wankel Rotary Engines

<div class="section abstract"><div class="htmlview paragraph">In a previous study it was shown that production vehicle employing Wankel rotary engine, the Mazda RX-8, easily capable of meeting much more modern hydrocarbon emissions than had been certified for. It contended this mainly due to its provision zero port overlap through adoption side intake and exhaust ports. In earlier work preliminary investigation conducted gauge impact adopting approach in peripherally-ported with significant reduction performance fuel economy being found.</div><div paragraph">The present builds on those initial studies by taking engine from testing an dynamometer. The results show best consumption is entirely line several proposed dedicated range extender engines, supporting contention excellent candidate for role. Also, continued 1-D modelling has potential route regain lost better turbocompound engine.</div><div paragraph">While compounding using turbomachinery provides one direction further work, new concept which uses conventional three-flank rotor two-lobe housing provide positive displacement compounder enable anywhere device. This will allow configure large unobstructive ports unimpeded timing. novel discussed paper.</div></div>
