Below in conjunction with drawings and Examples the utility model is further specified.Each accompanying drawing is:
Fig. 1 is the natural gas engine of a kind of tractor-truck of the present utility model and the arrangement structure and the car load scheme drawing of accumulator unit coupling;
The installation site and the structural representation of Fig. 2 A first and two liang of group natural gas cylinders;
The installation site of first group of natural gas cylinder of Fig. 2 B and structure side scheme drawing;
Fig. 3 is applicable to the natural gas engine of tractor-truck and the natural gas supply system schematic diagram that the accumulator unit coupling is used.
The specific embodiment
Introduce an embodiment of the present utility model to closing accompanying drawing below.
At first referring to Fig. 1, Fig. 1 has showed the natural gas engine of a kind of tractor-truck of the present utility model and the arrangement structure embodiment and the car load scheme drawing of accumulator unit coupling.In the present embodiment, natural gas engine CNG has gas storage system and natural gas supply system, described gas storage system gas cylinder group be horizontal layout, with and organize first and second steel gas cylinder group 1 and 3 of assembly 6 bonded assemblys, their adopt that second carriage 2 of support type carriage 4,5 and suspension type combines is connected and fixed structure and described natural gas engine CNG and is installed in outside rear cabin and the right vertical beam on the vehicle frame between the front axle and drive axle.Because installation site and the mode of natural gas engine CNG are identical with common engine, and common engine is installed and described rear cabin and right vertical beam outside front axle all are that this is known for those skilled in the art with drive axle and vehicle frame, no longer on drawing they is showed one by one for drawing is concisely clear and marks.Described gas storage system also can vertically be arranged, and can is a steel gas cylinder group.It is the structure concrete decision that concrete layout of gas cylinder group and fixed form can be looked concrete used tractor-truck by ordinary skill.
Fig. 2 A is a kind of first and two liang of installation site and fixed sturcture scheme drawing of organizing natural gas cylinder that the inventor recommends.Show among the figure that first and second steel gas cylinder group 1 and 3 is horizontal layouts, the second steel gas cylinder group 3 wherein places and the second fixing carriage 2 of vehicle frame.Second carriage 2 is suspended in below the first carriage first steel gas cylinder group 1, that be made of support type carriage 4,5 as can be seen from Fig. 2 A.
Fig. 2 B is the installation site and the structure side scheme drawing of first group of natural gas cylinder among Fig. 2 A.Show among the figure that the first steel gas cylinder group 1 is horizontal layout, the first steel gas cylinder group 1 wherein be supported in fixing first carriage that constitutes by support type carriage 4,5 of vehicle frame in.
A kind of high-power natural gas engine of heavy tractor-truck and natural gas supply system schematic diagram that natural fuels accumulator unit coupling is used of being applicable to that Fig. 3 inventor recommends.As can see from Figure 3: it have make gas cylinder and group and organize assembly 6, overcurrent protective device 7, to and organize assembly 6 gas filed gas filled devices 8; set gradually high-pressure ball valve 9, high pressure fil 10, pressure sensor 11, reducing valve 12, H Exch 13, combustion gas coolerstat 14 and driving engine CNG along air feed direction b; flow back to the driving engine district again after making the cooled hot water of driving engine CNG through described reducing valve 12, H Exch 13, combustion gas coolerstat 14; driving engine CNG is cooled off with this circulating water, but the natural fuels in reducing valve 12 grades is heated with this circulating water.Employed discrete-component all is to well known to a person skilled in the art prior art in the native system, therefore no longer makes introductions all round at this.
Carried out reasonably coupling according to the characteristic of automobile theory and natural gas engine, at cooling system, take into full account natural gas engine CNG flare point temperature than higher in the coupling of intake and exhaust system, its intercooler, radiatores etc. are with big with the more needed dissipating area of the diesel motor of equipower, in the one-level decompression process, need to absorb unimpeded (owing to small amount of moisture condensation icing accumulation that combustion gas rapid expansion may cause in combustion gas contain stop up reducing valve 12 and relevant fuel gas pipeline) of a large amount of heats in order to solve natural fuels simultaneously with the reducing valve 12 and the connecting line thereof of assurance because of rapid expansion, drawing from driving engine CNG cooling system without the refrigerant fluid of cooling gives reducing valve 12 heating, thereby reached the harmful effect that both prevents that fuel gas supply is not smooth or even stop up, well cooled off refrigerant fluid again.
Beneficial effect
The beneficial effects of the utility model are, vehicle uses natural fuels to be fuel, not only environmental protection more, and operation cost reduces significantly, and (fuel cost reduces by 30%～50%, part special user cost is reduced and can reach about 80%), simultaneously, because the burning-point of natural fuels spreads the own characteristic of escape easily than diesel oil height (being difficult for lighting) and natural fuels, and on pipeline, used two cutting ferrule high pressure sealing technology of tube material, made that operation is more safe and reliable.
Below listed subordinate list be a kind of preferred embodiment truck main technical details that has adopted the high-power natural gas engine and the natural fuels accumulator unit of heavy tractor-truck of the inventor.
