Temperature (oC)
MSU Fuels Investigations
? Canola-based FAMEs (CME) has relatively good cold flow properties & oxidative stability.
Dibutyl succinate (DBS)
? DBS further improves the cold flow properties of CME. ? To stay within the 40 CN U.S requirement, DBS
content in CME must be limited to 40%.
Single-Cylinder Study Objectives
Study the influence of selected oxygenated fuels on combustion and emissions in a modern diesel engine
? Conventional Combustion ? Low Temperature Combustion (LTC)
