Abstract: A thermochemical recuperation (TCR) system that may use a water-alcohol mixture as an engine liquid coolant; that may include a TCR reformer configured to output a TCR product at pressure no less than twenty bars; a pressure regulator; and an TCR product accumulator configured to separate an outputting of the TCR product by the TCR reformer from a provision of the TCR product to the pressure regulator; wherein the pressure regulator is configured to provide the TCR product to a direct injector of an engine, thereby enabling the direct injector to inject the TCR product at a high pressure level—for example at a pressure level that exceeds twenty bars.

Abstract: A sonic saturation system is provided that comprises at least one tank for containing a reservoir of liquid solvent; at least one gas-inlet in fluid communication with a gas compressor, for introducing gaseous solute into the reservoir, and at least one sonic agitator (146) for agitating the liquid reservoir thereby increasing the rate of impregnation of the solute into the solvent.
