Compared with the prior art, the compressed natural gas system assembly applicable to the Passat automobile has the advantages of being low in cost, convenient to maintain and mount and the like.
Description
Technical field
The present invention relates to a kind of automotive system assembly, especially relate to a kind of CNG system assembly that is applicable to Passat automobile.
Background technology
Along with expanding economy, Shanghai Volkswagen Passat type car is brought into use in increasing city, and under the trend constantly rising in Fuel Petroleum price, compression natural gas-gasoline double-fuel vehicle day benefit becomes the first-selection of vast taxicar.But with regard to Shanghai Volkswagen Passat vehicle, because it has adopted, driving engine is vertical puts form, adds the discharge capacity that it is larger, makes whole machinery space seem very full, lacks necessary CNG system installing space.
Previously, on Passat compression natural gas-gasoline double-fuel car that Volkswagen puts on display in German native country, 4 clean steel 40L gas cylinders processed have been adopted, after solenoid control flow regulating valve current limliting, as gas storage unit, combine output, whole unit is positioned under vehicle chassis; In machinery space, arrange special second depressurized device and the gas injection rail consistent with oil spout rail, control system integration is to fuel oil ECU.This kind of scheme, highly integrated, in whole fitting process, carry out the installation and debugging of CNG system, be not suitable for the production of non-car load manufacturing enterprise.System is used part height customization, lacks commonality, makes cost higher, is unfavorable for the popularization in market.
Summary of the invention
Object of the present invention is exactly that a kind of cheap and maintenance and the easy for installation CNG system assembly that is applicable to Passat automobile are provided in order to overcome the defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions:
A kind of CNG system assembly that is applicable to Passat automobile, this system synthesis comprises compressed natural gas cylinder, gas support, high pressure gas transmission hard tube, assembly bracket and engine component, described compressed natural gas cylinder is fixedly mounted on gas support, described gas support is connected with assembly bracket through high pressure gas transmission hard tube, and described engine component integrated installation is on assembly bracket.
On described gas support, be provided with gas cylinder bandage, suspension hook and hook on bolt, for being fixedly connected with compressed natural gas cylinder.
Described gas cylinder bandage adopts hot rolled steel plate to make and obtains.
Described engine component comprises compression natural gas inflation valve, high-voltage electromagnetic shutoff valve, pressure-modulation valve and the compression indicator of integrated installation on assembly bracket successively.
Described compression indicator is connected with gas injection rail through low pressure air hose.
Compared with prior art, the present invention has the following advantages:
One, cheap: the CNG system part using in this programme is general part, without specific customization, price is compared comparatively cheap with customization part.
Two, easy to maintenance: to reduce the use of integration member, during system et out of order, can from combustion gas computer, detect fault part, and change separately.Systematic part has highly versatile, purchases more convenient.
Three, easy for installation: this programme adopts the follow-up mode installing additional to carry out the repacking of compression natural gas-gasoline double-fuel to vehicle, by support, to part, carry out integrated, facilitate under line and pre-install and the always installation of member, the vehicle refitting enterprise that is applicable to non-car load production produces.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the main TV structure schematic diagram of assembly bracket;
Fig. 3 is the side-looking structural representation of assembly bracket;
Fig. 4 is the structural representation of gas cylinder mounting bracket.
In figure, 1 is that compressed natural gas cylinder, 2 is that gas support, 3 is that high pressure gas transmission hard tube, 4 is that compression natural gas inflation valve, 5 is that high-voltage electromagnetic shutoff valve, 6 is that pressure regulator, 7 is that compression indicator, 8 is that gas filter, 9 is that low pressure air hose, 10 is that gas injection rail, 11 is that combustion gas charge valve, 12 is that assembly bracket, 13 is that bandage, 14 is that suspension hook, 15 is hook on bolt.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
A kind of CNG system assembly that is applicable to Passat automobile, its structure as Figure 1-4, this system synthesis comprises compressed natural gas cylinder 1, gas support 2, high pressure gas transmission hard tube 3, assembly bracket 12 and engine component, compressed natural gas cylinder 1 is fixedly mounted on gas support 2, on gas support 2, be provided with and adopt hot rolled steel plate to make bandage 13, suspension hook 14 and the hook on bolt 15 obtaining, for being fixedly connected with compressed natural gas cylinder 1.Gas support 2 is connected with assembly bracket 12 through high pressure gas transmission hard tube 3, and engine component comprises compression natural gas inflation valve 4, high-voltage electromagnetic shutoff valve 5, pressure-modulation valve 6 and the compression indicator 7 of integrated installation on assembly bracket 12 successively.In addition, compression indicator 7 is also connected with gas filter 8, and this gas filter 8 is connected with gas injection rail 10 through low pressure air hose 9.
In the present invention, mainly by assembly bracket 12, fix pressure regulator 6, high-voltage electromagnetic shutoff valve 5 and compression natural gas inflation valve 4; By high pressure gas transmission hard tube 3, carry out the gas circuit between each part of UNICOM; Two mounting holes that assembly bracket 12 is located at lower end by it are connected with vehicle body, and systematic part is arranged in machinery space.Compressed natural gas cylinder 1 is connected with gas support 2 by bandage 13 and suspension hook 14, hook on bolt 15, formation gas cylinder installation module; Bandage 13 is connected with support by the bandage mounting hole on gas support 2; Gas support 2 is connected with car trunk floor by four mounting holes of its bottom surface, completes the fixing of gas cylinder.After high pressure gas transmission hard tube 3 penetrates at the bottom of car by baggage container, from fuel tank front end, cross at the bottom of car to vehicle opposite side, walk abreast toward front side to machinery space with oil transportation hard tube, then be connected with charge valve.
