ADSORBER OF FUEL EVAPORATION CONTROL SYSTEM Russian patent published in 2006 - IPC F02M25/08 F02M33/02 

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: invention relates to fuel systems of internal combustion engines with adsorbers of fuel evaporation control system absorbing fuel vapors from tank. Proposed adsorber of fuel evaporation control system contains hollow housing consisting of several parts, one of which is trap for collecting condensate (liquid hydrocarbon fuel). Adsorbing material is arranged in inner space of other part of housing. Three branch pipes are arranged on outer surface of housing part: branch pipe to supply fuel vapors to adsorbing material, branch pipe to remove fuel vapors from adsorbing material and branch pipe communicating inner space of housing with ambient atmosphere. Inner space of trap is provided with arrangement for connecting it with inner space of housing accommodating adsorbing material. Housing is furnished with additional trap whose inner space is provided with arrangement for connection with inner space of housing part accommodating adsorbing material. Branch pipe removing fuel vapors from adsorbing material is mounted on additional trap.

EFFECT: provision of entrapping of fuel vapors.
