The Twin Swirl “MR-Process” Combustion Mechanism and Conversion of Diesel Engines to Operate with Gaseous Fuels

Abstract

<div class="section abstract"><div class="htmlview paragraph">Converting diesel engines to cheaper and cleaner fuels like LPG and CNG, with conventional methods needs a different combustion chamber, which has a lower compression ratio than a diesel engine (≻16:1) due to risk of detonation. This alteration makes the conversion process more expensive and difficult. On the other hand, decreasing a compression ratio leads to lower performance and efficiency compared to those of the original engine.</div><div class="htmlview paragraph">To overcome this disadvantage it is proposed a novel mechanism for mixture formation and combustion, named as "MR-Process." This mechanism is realized in a combustion chamber MR-2 with twin-swirl turbulent flow. This chamber is suitable for operation with diesel fuels as well as with LPG and NG.</div><div class="htmlview paragraph">In this paper are presented theoretical and experimental investigations of engines operating with "MR-Process" combustion mechanism.</div></div>
