Following hydrogen manufacturing engine fuel system

Abstract

A follower hydrogen-manufacturing engine fuel system which uses liquid hydrogenous fuel airborne follower to be catalyzed and transformed into mixed hydrogenous gas and uses the mixed hydrogenous gas as engine fuel is characterized in that the follower hydrogen-manufacturing engine fuel system is provided with a hydrogen-manufacturing system (1) which uses reproducible water function; a hydrocarbon-applied type system uses the compact follower hydrogen-manufacturing device (c) of an integral desulfurizing cavity (004); the system is simple and compact and takes little space; no scaling occurs during the process of manufacturing hydrogen; the continual mileage of a constant-volume fuel tank locomotive is long, which is convenient to be practical.

Description

Technical field [0001] The invention relates to a hydrogen-rich engine fuel system that uses liquid hydrogen-containing fuel (low-carbon alcohol or hydrocarbon, etc.) The utility model relates to an on-board hydrogen production engine fuel system for mixed combustion of mixed gas and liquid hydrogen-containing fuel, which is especially suitable for transport machinery such as vehicles and ships, and belongs to the technical field of engines and energy sources. Background technique [0002] With the continuous depletion of oil resources and increasing emission pressure day and night, the search for environmentally friendly alternative energy has long been concerned by countries all over the world. Hydrogen and biomass low-carbon alcohols (such as ethanol, etc.) have become recognized as ideal clean and alternative energy sources. [0003] As the direct energy source of the engine, hydrogen fuel has the outstanding advantages of high energy conversion efficiency, good power p...

Problems solved by technology

So far, it can be said that the problem of fouling and extremely short mileage of the on-board hydrogen production system of the existing known technology is one of the important reasons that hinder the rapid practical application of on-board hydrogen production technology

[0008] 2. The hydrocarbon fuel system needs to add a special desulfurization device. The system structure is complicated. It is very important to reduce the weight or simplify the system equipment and pipelines for the limited space of the mobile locomotive and reduce the fuel consumption.

[0009] 3. The hydrogen produced in the accompanying hydrogen production system is a hydrogen-rich mixed gas. The engine fuel system using the mixed gas will expose the weakness of insufficient power when the locomotive needs to run at a high load, because the non-combustible components in the hydrogen-rich mixed gas are diluted If the calorific value of the fuel gas is exceeded, when the locomotive is in a high-load operating condition, it will show the phenomenon that the fuel calorific value is insufficient and the engine power will drop

[0010] In addition, pure hydrogen vehicles (such as CN1800617A, etc.) that require ground hydrogen charging are also hydrogen hybrid vehicles (such as BMW’s hydrogen-gasoline hybrid vehicles, etc.), in order to ensure the driving range of the vehicle, it is necessary to use a high pressure of 35-90 MP Or filling with ultra-low temperature liquid hydrogen at minus 273°C, high-pressure hydrogen storage will inevitably significantly increase the manufacturing cost of locomotives
