Supply system for supplying fuel e.g. petrol, to internal combustion engine of hybrid car, has retention device to retain fuel vapor, and heat exchanger installed in fuel tank or on flow conduit network for cooling fuel and/or fuel vapor

摘要

The system (1) has a tank (4) for storing fuel (41), and a retention device (5) for retaining fuel vapor, where a flow conduit network (6) is provided for the flow of the fuel vapor. A heat exchanger (7) is installed in the tank or on the flow conduit network for cooling the fuel and/or fuel vapor, where the heat exchanger includes an envelope (71) containing a phase change material (72) for storage of latent heat. The flow conduit network includes a fuel vapor extraction conduit (61) with an input connected to the tank, and an output connected to the retention device.
