FIELD: engines and pumps.
SUBSTANCE: invention relates to fuel feed systems of internal combustion engines (ICE). ICE fuel feed system using fuel solution (FS) containing: absorber (33) for preparation of fresh FS by spraying liquid fuel in gas medium, an flow activator (45), FS recirculation loop which includes line of FS supply to pump-injectors; pump-injector; line of FS return; heat exchanger (52) for cooling FS return flow from ICE; separator (33) for separation of fuel vapors released in return flow; valve (54) for increasing FS pressure in feed line before pumps-injectors; mixing device (46) for adding fresh FS into re-circulated FS; line for supplying pilot dose of FS in air supply channel and lines of blowing absorber and separator with discharge of vapours and gases in air supply channel. Also disclosed is a method of preparing fuel, implemented using said system.
EFFECT: purpose of invention consists in improvement of economy and reduction of ICE toxicity.
