U Mich study explores performance of renewable diesel, FT diesel and ULSD in PCCI combustion

Green Car Congress

A team at the University of Michigan has investigated the performance of three different fuels—ultralow sulfur diesel (ULSD), diesel fuel produced via a low temperature Fischer–Tropsch process (LTFT), and a renewable diesel (RD), which is a hydrotreated camelina oil under partially premixed compression ignition (PCCI) combustion.
