Study finds use of high cetane fuel reduces all primary pollutants under advanced diesel combustion mode

Study finds use of high cetane fuel reduces all primary pollutants under advanced diesel combustion mode 24 April 2011 Comparison of optimized start of injection of advanced diesel combustion for brake thermal efficiency, NOx , PM, THC, and CO of diesel (open bar); HTFT (gray bar); and LTFT (black bar) fuels.

A high ignition quality (high cetane number) fuel is well suited for operation under an advanced diesel combustion mode (High Efficiency Clean Combustion, HECC) and leads to reductions in all primary pollutant emissions—i.e., THC and CO as well as NOx and PM—according to research by a team from The Pennsylvania State University. HECC mode, a premixed charge compression ignition (PCCI) process (a Low Temperature Combustion, LTC, process), is achievable in current production diesel engines by modifying several engine ope...
