"In Mainspring’s linear generator, electrically-controlled linear motion of oscillators compress a fuel and air mixture until the mixture reacts uniformly and near instantaneously without a flame or burning. Since there is no flame or burning (i.e., no combustion), the reaction occurs at low
temperatures (less than 1500 C) and, as a result, produces near-zero NOx emissions."

"Mainspring’s linear generator uses a low-temperature, uniform reaction that maintains peak temperatures below the levels in which NOx forms (1500°C), resulting in near-zero NOx emissions. This is in contrast to the burning of a fuel with a flame, which creates high temperatures and high NOx emissions."
That still is combustion but probably using something like homogeneous charge compression ignition (HCCI).

Hi Trevor, sorry for being slow picking up on this. I had never come across HCCI. Thank you that. Much appreciated!
