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).
How do these combustion techniques work, and how do they improve efficiency and emissions? Check out the video for all the details!/Engineering Explained
