Novel vehicle liquid hydrogen bottle and LNG vehicle bottle gas supply system

Abstract

The invention discloses a novel gas supply system for a vehicle liquid hydrogen bottle and an LNG vehicle bottle. The gas supply system aims at solving the problems that an existing vehicle-mounted liquid hydrogen container is tedious in pipeline, complex in operation, high in cost, not high in automatic control system and the like. The gas supply system comprises a vehicle bottle, a filling pipeline used for filling is arranged on the vehicle bottle, a gas using pipeline used for supplying gas to a vehicle body is arranged on the filling pipeline in a communicating mode, and a pressure maintaining pipeline used for maintaining pressure is arranged on the vehicle bottle. Through the common-port design of the filling pipeline, the pressure maintaining pipeline and the gas using pipeline, the pipeline process is obviously optimized, then the pipeline layout space is greatly saved, the production cost of products is greatly reduced, the competitive advantage of enterprises is greatly increased, and through the arrangement of the pressure maintaining pipeline, the production efficiency is greatly improved. In actual use, different pressure conditions in the vehicle bottle can be effectively adjusted, and then the stability of air supply pressure is greatly guaranteed.

Description

Technical field [0001] The invention belongs to the technical field of automobile gas supply systems, and specifically relates to a gas supply system for a new vehicle liquid hydrogen bottle and an LNG vehicle bottle. Background technique [0002] Natural gas dual-fuel vehicles are recognized in the world as energy-saving, low-pollution, economical and safe new alternative fuel vehicles. Generally, there are two sets of fuel supply systems. One system supplies natural gas or liquefied petroleum gas, and the other supplies fuel other than natural gas or liquefied petroleum gas. The two fuel supply systems supply fuel to the cylinder according to a predetermined ratio. Mixed combustion vehicles, such as CNG-diesel dual-fuel vehicles, or LPG-diesel dual-fuel vehicles. This type of vehicle uses CNG (or LPG) as the main fuel, and diesel serves as ignition. [0003] Both liquid hydrogen and liquefied natural gas (LNG) are ultra-low temperature flammable and explosive media. Howe...
