Homogeneous Charge Compression Ignition Combustion: Advantages Over Compression Ignition Combustion, Challenges and Solutions [PDF]

open access: yes, 2016
The homogeneous charge compression ignition (HCCI) engine uses a relatively new mode of combustion technology. In principle, there is no spark plug or injector to assist the combustion, and the combustion auto-ignites in multiple spots once the mixture ...
