An Investigation Of Kinetic Effects Of Split Injection Timing On Low Temperature Combustion, Tejaswini A. Kamble Jan 2014

An Investigation Of Kinetic Effects Of Split Injection Timing On Low Temperature Combustion, Tejaswini A. Kamble

Wayne State University Theses

Low temperature combustion (LTC) modes of operating internal combustion engines are of great interest for their potential to achieve high thermal efficiencies while maintaining low nitrogen oxide (NOX) and particulate matter emissions below levels requiring costly after-treatment systems. While various strategies for realizing LTC have been developed, including homogeneous charge compression ignition (HCCI), reactivity controlled compression ignition (RCCI) and premixed charge compression ignition (PCCI), a common challenge is the control of the kinetically-driven auto-ignition processes over appreciable load ranges.

This study examines the chemical kinetics of split-injection timing and the kinetic effect of this parameter on combustion phasing and pressure …
