Cross aerating panel assembly, CNG gas valve assembly and first manual stop valve to be connected with an import of three-way valve, described LNG gas
The gas outlet of bottle passes sequentially through the another of the carburator of band surge tank, LNG gas valve assembly and the second hand stop valve and three-way valve
One import connects.
Concrete, described CNG gas valve assembly includes high pressure filter, decompressor and the low pressure cleaner being sequentially connected with,
The import of described high pressure filter is connected with the gas outlet of CNG gas cylinder by aerating panel assembly, and the outlet of low pressure cleaner is led to
Cross first manual stop valve to be connected with an import of three-way valve.
Concrete, described LNG gas valve assembly includes manostat, electromagnetic valve and the low pressure cleaner being sequentially connected with, described
The import of manostat is connected with the outlet of the surge tank of carburator, and the outlet of described low pressure cleaner is by the second hand stop valve
It is connected with an import of three-way valve.
Concrete, the quantity of described CNG gas cylinder is seven, and described seven CNG gas cylinders are connected in parallel, described LNG gas cylinder
Quantity be one.
The beneficial effects of the present invention is: the present invention has CNG gas cylinder in aisle, passenger vehicle stage casing arranged beneath, simultaneously at vehicle
Tail end is arranged above LNG gas cylinder, CNG gas cylinder and LNG gas cylinder and is connected in parallel by respective gas valve group and associated component
The fuel gas supply of rear connection electromotor；The present invention can facilitate passenger vehicle fueling process between different cities, both can be in CNG aerating
Station carries out aerating, it is also possible to carry out aerating in LNG gas station, simultaneously because having two set gas burning systems on same passenger vehicle concurrently, carries
Fuel quantity have also been obtained and be greatly improved, add the course continuation mileage of passenger vehicle.
