Title:
EVAPORATIVE FUEL GAS COOLING STRUCTURE
Document Type and Number:
Japanese Patent JP2019157793
Kind Code:
A
Abstract:
To provide an effective treatment structure for evaporative fuel gas flowing in a ventilation passage communicating a fuel tank and a canister, which uses supplied fuel.SOLUTION: A spiral metal pipe 2 fixed to the inner wall of a fuel supply pipe 3 is disposed in a ventilation passage communicating a fuel tank 4 and a canister 7. When fuel is supplied, supplied fuel 81 directly contacts with the spiral metal pipe 2, heat exchange between evaporative fuel gas 43 in the high-temperature fuel tank 4 and the low-temperature supplied fuel 81 is performed through the spiral metal pipe 2, the evaporative fuel gas 43 is cooled, then the saturated vapor pressure of the evaporative fuel gas 43 decreases, and thus an amount of the evaporative fuel gas 43 flowing out to the canister 7 can be reduced.SELECTED DRAWING: Figure 1
