Homogeneous charge compression ignition (HCCI) engine operation offers the potential to provide fuel economy approaching that of traditional diesel engines, with increased compression ratios and low pumping losses, while simultaneously emitting low NOx and soot due to the homogeneous, low temperature nature of the combustion. HCCI, however, comes with unique challenges as fuel mixture chemical kinetics supplant direct ignition timing control via spark ignition or injection timing. Improved understanding of the ignition phenomena that control in-cylinder combustion phasing and duration in HCCI engines can help overcome the challenges of HCCI. In particular, spark-assisted HCCI combustion has been proposed as a means to extend HCCI operating limits and to facilitate transition between spark-ignition and HCCI operating modes.Harold Schock (Michigan State Univeristy) generously provided a copy of the FEV usera#39;s manual for an identical assembly.
