ABSORBING BOWL FOR CONTROL OF EMISSIONS FROM FUEL TANK OF VEHICLE AND FUEL TANK COMPRISING SUCH BOWL Russian patent published in 2013 - IPC F02M25/08 B01D53/04 

FIELD: power engineering.

SUBSTANCE: absorbing bowl (30) for control of emissions from a fuel tank of a vehicle, comprising the following: a tubular first layer of adsorbent (14), a nozzle of a fuel tank (10), a blowdown nozzle (12), the second layer of adsorbent (20), a through channel (18). The first (14) and second (20) layers of adsorbent (14) are made of activated coal. The first layer (14) has a side (54) and a central (62, 64, 66) walls. The side (54) and central (62, 64, 66) walls form an inner channel via the bowl. The nozzle of the fuel tank (10) communicates with the first end of the first layer of adsorbent (14) and is connected with an evaporation pipeline of the fuel tank. The blowdown nozzle (12) communicates with the first end of the first layer of adsorbent (14) and is connected with a blowdown pipeline of the motor. The second layer of adsorbent (20) is arranged in the inner channel. A through channel (18) communicates with the second end of the first layer of adsorbent (16) and with the first end of the second layer of adsorbent (20) for connection of the first (14) and second (20) layers of adsorbent in series. The through channel (18) comprises a heat exchanger (60). The heat exchanger (60) is arranged as capable of heat exchange between the first layer of adsorbent (16) and atmospheric air. The heat exchanger (60) is divided inside with partitions (102, 104, 106, 108) for direction of air along a crooked path (60a-60d) along the outer wall of the first layer of adsorbent (16). Also a fuel tank is provided in a vehicle, having an absorbing bowl.

EFFECT: provision of heat exchange between air in a bowl and environment.
