Problems solved by technology

However, two sets of gas storage equipment will take up valuable space, and there are problems in the design that are not easy to realize
The disadvantage of the second method is that it is impossible to change the fuel quality, and because of the low density of hydrogen, it will occupy the upper layer of the fuel tank, so that the properties of the mixture will change with the pressure of the fuel tank.
At the same time, in terms of infrastructure construction, since there is no hydrogen supply station in my country, it makes the promotion and application of hydrogen more difficult.

Embodiment Construction

[0015] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0016] Such as figure 1 The gas supply system shown mainly includes a natural gas cylinder 1 , a gas pipeline and an engine 3 . The natural gas cylinder 1 communicates with the engine 3 through a gas pipeline, and part of the gas pipeline is connected in parallel with a hydrogen production branch. The gas pipeline before the hydrogen production branch starts from the gas outlet of the steel cylinder and passes through the filter 11a, the flow restrictor 12, the flow meter 13 and the dryer 14 in sequence. The hydrogen production branch is connected with a sliding arc reactor 2 and a filter 11b. There is a valve 4 on the gas pipeline parallel to the hydrogen production branch, which cooperates with the flow limiter 12 to control the ratio of the mixed gas; the combined pipeline is connected to the engine 3 after passing through the flow indi...

Abstract

The invention provides a natural gas hydrogen production HCNG engine gas supply system which comprises a natural gas steel bottle, a gas pipe system and an engine. The natural gas steel bottle is communicated with the engine by the gas pipe system. Part of the gas pipe system is connected with a hydrogen production branch in a parallel way. The hydrogen production branch is connected with a sliding arc reactor which is connected with a power supply by a variable ratio transformer. The system electrolyzes part of single fuel (natural gas) of the natural gas hydrogen engine to obtain hydrogen of proper flow rate to be mixed into HCNG fuel and solves a series of problems of hydrogen station infrastructure, hydrogen fuel storage, hydrogen fuel transportation, and the like.

Description

technical field [0001] The invention relates to a gas supply system for a natural gas engine vehicle, in particular to a natural gas hydrogen production type HCNG engine gas supply system. Background technique [0002] In 2007, the output of natural gas vehicles (including chassis) in my country reached 57,000 units, covering multiple market segments such as passenger cars, cars, trucks, and municipal special vehicles. At present, 58 enterprises in my country have produced natural gas vehicles, and a total of 347 natural gas vehicle models (including chassis) have entered the national motor vehicle new product announcement. There are 18 domestic enterprises producing natural gas engines, and a total of 98 natural gas engine products are sold in the market. [0003] Although the emission of natural gas combustion is less than that of gasoline and diesel, and it has good anti-knock performance, its combustion rate is low and the combustion is not stable when it is lean, which...
