TANK VENTILATION AND COOLING SYSTEM FOR HYBRID VEHICLES

摘要

A deaeration and cooling system for a fuel tank of an internal combustion engine includes an absorption refrigerator configured to cool fuel in the fuel tank. The absorption refrigerator includes a burner, an evaporator and an exhaust-gas heat exchanger. Thermal energy for operating the absorption refrigerator is obtained from the combustion of evaporated fuel. The evaporated fuel is removed from the fuel tank and supplied to the burner of the absorption refrigerator.
