HCCI Operation of a Multi-Cylinder Engine

Research output: Chapter in Book/Report/Conference proceedingPaper in conference proceeding


A six-cylinder truck-size engine has been converted for Homogeneous Charge Compression Ignition (HCCI) operation. This work demonstrates that it is possible to run a multi-cylinder engine under HCCI operation. The ultra-low NOX characteristic of HCCI is also demonstrated. The sensitivity of combustion timing with respect to operating parameters is investigated, and a closed-loop control system is designed which utilizes the mixing ratio of two different fuels to control the timing of combustion. The performance of the control system is evaluated experimentally.
