RETURN FUEL COOLING SYSTEM FOR LPI VEHICLE

摘要

A return fuel cooling system for an LPI vehicle includes: an engine radiator, a cooling fan blowing wind to the engine radiator, and a first reservoir tank connected with the radiator through a first cooling line, and cooling an LPI engine; a fuel cooling radiator at the front end of the engine radiator, a second reservoir tank connected with the fuel cooling radiator through a second cooling line, and a water pump on the second cooling line to circulate cooling fluid, and circulating the cooling fluid to an air-conditioner to cool the refrigerant; and a fuel cooler connected with the second cooling line between the fuel cooling radiator and the water pump such that cooling fluid passing through the air-conditioner is circulated in the fuel cooler and connected with the LPI engine and the bombe through a fuel return line.

1. A return fuel cooling system for an LPI vehicle, comprising:
an engine cooling assembly cooling an LPI engine, the engine cooling assembly including an engine radiator provided at a front end of a vehicle, a cooling fan blowing air through the engine radiator, and a first reservoir tank storing a cooling fluid and connected with the engine radiator through a first cooling line; a refrigerant cooling assembly including a fuel cooling radiator at the front end of the engine radiator of the engine cooling assembly, a second reservoir tank storing the cooling fluid and connected with the fuel cooling radiator through a second cooling line, and a water pump on the second cooling line to circulate the cooling fluid to the air-conditioner assembly to cool the refrigerant through heat exchange with the refrigerant; and a fuel cooler connected with the second cooling line between the fuel cooling radiator and the water pump such that the cooling fluid passing through the air-conditioner assembly is circulated in the fuel cooler and connected with the LPI engine and the bombe through a fuel return line to cool the LPG fuel returned from the LPI engine and allow the cooled LPG fuel to be introduced into the bombe.
