The utility model provides an improved
fuel oil evaporation structure which comprises a main
oil tank, an auxiliary
oil tank, a motorcycle frame body, an
activated carbon tank, a
fuel oil filter and a carbon tank
electromagnetic valve and further comprises a dumping valve, a first
evaporation oil
pipe, a second
evaporation oil
pipe, a third evaporation oil
pipe and a fourth evaporation oil pipe. According to the
fuel oil evaporation structure, the arrangement of the fuel oil evaporation structure is optimized, a fuel oil pipeline is shortened, wiring in the middle of the pipeline is reduced, and therefore the flowing resistance of fuel oil flowing is reduced, and the fuel oil evaporation structure has the advantages of being energy-saving, environment-friendly, energy-saving, environment-friendly, energy-saving, environment-friendly, energy-saving, environment-friendly, energy-saving, environment-friendly, energy-saving and environment-friendly. Moreover, as the connection points of the pipelines are reduced, the leakage of fuel steam is reduced, the pipelines are reduced, the material cost in production is reduced, and the later maintenance cost is also reduced; meanwhile, the
utilization rate of the space in the vehicle is higher.
