Abstract
In a context of a fossil reserve depletion and reduction of
greenhouse gases (GHG) emissions, the search for new energy for
transport is fundamental. Among those new energies, alternative
fuels and especially synthetic fuel from Fischer-Tropsch process
(so-called XtL, "X-to-Liquid" fuels) seem to have an
interesting potential in terms of availability and GHG emission
reduction, according to the feedstock used.
Due to the special properties of such products, especially high
cetane number, several strategies of incorporation can be
envisaged: as a blend in specific basestocks in order to obtain a
conventional fuel or a premium fuel or as a pure component. In
order to assess these strategies; a standard diesel fuel (B0), a
blend with 40%vol of Fischer-Tropsch and a neat Fischer-Tropsch
have been tested on a modern downsized high pressure direct
injection single-cylinder diesel engine. The used Fischer-Tropsch
fuel is a commercial GtL - Gas to Liquid, with a cetane number
higher than 80.
First, engine tests have been performed with the same engine
settings than the B0 fuel in order to evaluate the impact of the
fuel formulation on the combustion behavior and on the engine
outputs. Then, the engine settings were optimized for each fuel in
order to achieve the best engine outputs, and so, evaluate the
intrinsic performance of the tested fuels.
This study allows understanding the influence of high
auto-ignition fuels with low aromatic content on pollutant
emissions at low speed/low load conditions (1500 rpm 3 bar of IMEP)
and also on performances at full load. Without a dedicated
calibration, the Fischer-Tropsch-based fuels induce a noticeable
modification of the combustion process and engine outputs. The full
potential of such fuels can only be achieved after a dedicated
optimization of engine settings. This optimization enables to
reduce HC and CO emissions at low speed/low load and increase the
effective power at full load thanks to a smoke emission
decrease.
Some of these tests have received funding from the European
Community's FP7 under grant agreement n° 218890
"OPTFUEL."
