The Twin Swirl “MR-Process” Combustion Mechanism and Conversion of Diesel Engines to Operate with Gaseous Fuels 2011-24-0066
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.
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
In this paper are presented theoretical and experimental
investigations of engines operating with "MR-Process"
