The invention discloses a common rail hydrogen injection system for a fuel cell vehicle. The common rail hydrogen injection system comprises a hydrogen source, a working pipeline, an integrated plug-in gas cylinder combination valve, a hydrogen filling port, a hydrogenation pipeline, a one-way valve, a flow-limiting valve, an integrated plug-in hydrogen gas collecting valve, a two-stage pressure reducing valve, a common rail injector, a control system, a fuel reaction battery reactor, an excess flow valve, an easy flow plug, an emptying pipeline, an emptying battery valve and an emptying port,wherein the hydrogen source is connected with the integrated plug-in gas cylinder combination valve, the integrated plug-in hydrogen gas collecting valve, the two-stage pressure reducing valve, the common rail injector and the control system in sequence through the working pipeline; the hydrogenation pipeline passes through an inflation pipeline, the one-way valve and the flow-limiting valve. Byadopting the common rail hydrogen injection system, the effects of higher responsiveness at a large flow and higher stability at a small flow and higher integrity can be achieved.
Description
technical field [0001] The invention belongs to the technical field of fuel cells, in particular to a common rail hydrogen injection system for fuel cell vehicles. Background technique [0002] At this stage, new energy vehicles mainly include pure electric vehicles, hybrid vehicles, and fuel cell vehicles. Fuel cells, as the power source of a new generation of fuel vehicles, have been regarded as strategic products by major countries in the world, and major automobile companies are all committed to the research and application of fuel cells. Hydrogen fuel cell vehicles are the most widely used because of their advantages such as zero emissions, fast hydrogen refueling speed, and considerable cruising range. When the fuel cell is in use, hydrogen needs to be provided externally. When the hydrogen needs to be replenished, the traditional method is to replace the hydrogen storage container. However, because the hydrogen storage container is relatively heavy, it brings a lot o...
