Abstract

The invention relates to the technical field of vehicle-mounted gas cylinder pressurization control, and discloses a vehicle-mounted gas cylinder pressurization control system and a control method thereof. The vehicle-mounted gas cylinder pressurization control system includes a gas cylinder body, a first shut-off valve, a first vaporizer and a buffer tank connected in sequence, and also includes a booster assembly, a booster pump, a second shut-off valve, a gas cylinder body, and a booster assembly. , the booster pump and the second shut-off valve are connected end to end in sequence; the fuel in the gas cylinder body can flow through the booster assembly, the booster pump, the second shut-off valve in turn, and return to the internal pressure of the gas cylinder body; the fuel in the gas cylinder body is returned It can flow through the second shut-off valve and the booster pump in turn and enter the buffer tank. The vehicle-mounted gas cylinder pressurization control system disclosed in the present invention can not only realize the self-pressurization of the gas cylinder body, but also can realize the active pressurization of the fuel in the gas cylinder body. The pressure relief and excess fuel is stored in the buffer tank to achieve the purpose of saving fuel.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted gas cylinder pressurization control, in particular to a vehicle-mounted gas cylinder pressurization control system and a control method thereof. Background technique [0002] At present, domestic liquefied natural gas filling stations generally provide unsaturated liquefied natural gas. In order to ensure the normal use of liquefied natural gas vehicles, these vehicles are equipped with pressurization devices to pressurize the on-board gas cylinders of natural gas vehicles. [0003] At present, the vehicle-mounted gas cylinders are mainly boosted by the air-bath finned self-pressurization system and the active pressurization system with a booster pump. The air-bath finned self-pressurization system has a simple structure and good reliability, but the main problem is The reason is that the supercharging speed is slow. Even if a large-diameter pipeline is used, the supercharging rate is stil...
