If we want more efficient engines, with cleaner emissions, we’re going to need improved technologies and methods. Low temperature combustion promises greater efficiency with better emissions.

Recent examples include homogenous charge compression ignition (HCCI), premixed charged compression ignition (PCCI), and reactivity controlled compression ignition (RCCI).
