Investigation of Clean Diesel Combustion With Oxygenated Fuels in a Constant -Volume Combustion Chamber Using Forward Illumination Light Extinction Technique
The mechanism of soot reduction from oxygenated fuels was explored. DBM and TPME oxygenated fuels with 7% oxygen by weight were studied and have shown different soot reduction performances at different diesel combustion modes. In the premixed combustion mode, the higher oxygen efficiency from TPME …
