Embodiment Construction

[0034] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] The invention provides a CNG gas pipeline system with double gas filling ports for passenger cars, and provides a CNG system design and layout structure with double gas filling ports for passenger cars, which is convenient for gas filling.

[0036] Such as figure 1 As shown, the CNG gas pipeline system includes two sets of gas filling control valve assemblies 100 connected in parallel, one set of gas storage tank assemblies 200 and one set of master control valve assemblies 300 . The first outlet of the gas filling control valve assembly of the two groups communicates with the main control valve assembly through the three-way valve one 400, and the other outlet of the gas filling control valve assembly of the two groups communicates with the gas storage tank assembly through the three-way valve two 500. The general control valve assemb...

Abstract

The invention provides a CNG gas pipeline system with double gas filling ports for passenger cars, which includes two sets of gas filling control valve assemblies connected in parallel, a set of gas storage tank assemblies and a set of main control valve assemblies. One outlet of the control valve assembly is connected to the main control valve assembly through the three-way valve one, and the other outlet of the two groups of the gas filling control valve assemblies is connected to the gas storage tank assembly through the three-way valve two, and the main control valve assembly is connected to the CNG engine gas inlet connection. The system adopts a double gas filling port structure, which is convenient for users to fill gas. The two gas filling ports can be inflated at the same time to improve gas filling efficiency.

Description

technical field [0001] The invention relates to the technical field of gas vehicles, in particular to a CNG gas pipeline system with double filling ports for passenger cars. Background technique [0002] CNG (short for Compressed Natural Gas) vehicles are increasingly showing strong development potential due to their advantages such as low emissions, no pollution, safety and convenience, and superior economic benefits, especially for large passenger vehicles in urban traffic. Large buses use CNG as fuel, and CNG gas cylinders are used as fuel containers on board. However, at present, the gas filling port of the CNG gas pipeline on large buses is only set on one side of the vehicle, which is inconvenient for users to fill gas, and CNG gas The cylinders are mainly supported on the bottom frame longitudinally, the number of gas storage cylinders is small, and the driving range of CNG buses is insufficient. Contents of the invention [0003] The invention provides a CNG gas p...
