A fuel vapor adjusting device includes an expansion chamber at a top portion of a fuel tank; an oil spill trip valve being connected to the expansion chamber, which can turn off when there's spilling oil or the fuel tank is fell down; and at least two canisters. Each canister includes a fuel vapor entrance port, a fuel vapor outlet port, and a fuel vapor recycling vent. The fuel vapor entrance port and the fuel vapor outlet port form a fuel vapor filtering passage, and the fuel vapor entrance port and the fuel vapor recycling vent form a fuel vapor recycling passage. The oil spill trip valve, the at least two fuel vapor filtering passages connect in series, and the oil spill trip valve, the at least two fuel vapor recycling passages connect in parallel.

External fuel vapor emission adjusting device for fuel tank

A fuel tank includes a canister and a fuel control valve arranged in an expanding room. The canister has two guiding pipes communicated respectively with an entrance of an engine and environment. The fuel control valve is communicated with the expanding room. A double-lane valve is arranged between the canister and the fuel control valve. The double-lane valve has an entrance communicated with the fuel control valve, an exit communicated with the canister, a first valve and a second valve arranged between the entrance and the exit. The second valve withstands a spring and is arranged on the first valve. The first valve can detect an expending press produced by volatilized fuel gas to control whether the fuel gas enter into the entrance of the engine. The second valve can detects a vacuum press of the fuel tank to control whether air enter into the fuel tank.

Fuel tank having functions of adjusting press produced by fuel volatilizing and preventing fuel overflowing

A device combines a fuel control valve in a hollow can and a carbon canister, which can be further combined with a fuel tank. The device has a first chamber for preventing draining fuel and a second chamber containing active carbon. The first chamber is formed with a gas tube which is connected to the fuel tank and a gas channel connected to the second chamber. The second chamber is formed with a gas return tube. As such, the device combining the fuel control valve and the carbon canister is constructed. The hollow can is assembled to a lateral wall of the fuel tank and the gas tube can be connect with the fuel tank to form an integral structure.

Device combing fuel control valve and carbon canister, or fuel tank

A device combining a two-way valve and a carbon canister includes a hollow can, which can be further combined with a fuel tank. The device has a first chamber for regulating inner pressure of the fuel tank and a second chamber containing active carbon. The first chamber is installed with a gas tube which is connected to the fuel tank and a gas channel connected to the second chamber. The second chamber is installed with a gas return tube so as to form the device combining the two-way valve and the carbon canister. The hollow can is assembled to a lateral wall of the fuel tank and the gas tube can be embedded into the fuel tank to form an integral structure.
