VEHICLE FUEL CRYOGENIC TANK

摘要

FIELD: transport engineering; vehicles operating on liquefied natural gas. SUBSTANCE: cryogenic tank has hermetically sealed hood accommodating reservoir for liquefied natural gas secured on heat insulating supports. Reservoir is provided with devices for filling in, draining and delivering liquefied natural gas into fuel system of vehicle. Reservoir for liquefied natural gas is coupled with supports for movement by means of trunnions radially secured on reservoir in plane passing through its center of masses. Liquefied natural gas delivering device is furnished with fuel evaporator employing the heat of engine cooling system. Draining device can be connected to additional filling line of liquefied natural gas source when filling the reservoir along two lines and is provided with fuel sprayer in form of perforated tube. When filling the reservoir through one line, tube serves to entrap draining vapors. EFFECT: enlarged operating capabilities. 2 dwgi
