Advanced Ignition Control Technology for HCCI Combustion

Article of Honda R&D Technical Review Vol.26 No.2

Summary

Spark-Assisted HCCI combustion, which assists ignition by igniting direct injection spray with a spark, has been proposed to help enable the practical realization of homogeneous charge compression ignition combustion, thereby achieving high thermal efficiency. This method increases the controllability of ignition, an issue of homogeneous charge compression ignition, and expands the range of ignition combustion by a maximum of three times compared to the conventional method.
The fuel efficiency of Spark-Assisted HCCI was verified, with results indicating a decrease of 16% in steady-state fuel consumption against cooled EGR combustion technology and a JC08 mode fuel efficiency simulation showing an increase of 4.5% in fuel efficiency.
