Embodiment

[0029] The inventor adopts the above-mentioned hydroalcohol reforming fuel supply system, and successively refits the BJ492Q carburetor gasoline engine and the EQ6100 electronically controlled gasoline injection gasoline engine into a gasoline-hydrous alcohol reforming gas dual-purpose fuel engine, and refits "Dongfeng Xiaokang" accordingly. K07" and "YK6100" gasoline-hydrous alcohol reformed gas dual-purpose fuel prototype vehicles. The engine bench and vehicle road test results show that:

[0030]1. Can burn 100% water-containing alcohol on traditional ignition engines;

[0031] 2. It can automatically realize the mutual conversion between the two fuels of "gasoline" and "hydrous alcohol", basically without changing the operating habits of the operator;

[0032] 3. When the working condition of the engine changes, it can automatically stabilize the pressure of alcohol reformed gas within a certain range, so that it can be stabilized within the design range;

[0033] 4. The...

Abstract

The invention provides an alcohol reforming fuel feed system for a gasoline and aqueous alcohol reformed gas dual-purpose fuel engine, which comprises an aqueous alcohol feed subsystem, an aqueous alcohol reforming subsystem, an aqueous alcohol reformed gas feed subsystem and a control subsystem. An electromagnetic disconnecting valve (16) is arranged on a reformed gas pipeline (30) between the aqueous alcohol reforming subsystem and the engine, and is controlled by a pressure relay (3). The control end of the pressure relay (3) is communicated with the reformed gas pipeline (30). The reformed gas pipeline (30) in front of the disconnecting valve is provided with a reformed gas pressure inhibitor (12). The inhibitor (12) is connected with the reformed gas pipeline (30) through connecting lines (27) and (28). An electromagnetic disconnecting valve (14) is arranged on the connecting line (27), and is controlled by a pressure relay (15). The control orifice of the pressure relay (15) is communicated with the reformed gas pipeline (30). A gas feedback one-way valve (13) is arranged on the connecting line (28).

Description

technical field [0001] The invention relates to a gasoline-hydrous alcohol reformed gas dual-purpose fuel engine alcohol reforming fuel supply system, which belongs to the technical field of mixed combustion of gasoline and alcohol fuels. Background technique [0002] The application technology of biomass fuels represented by ethanol (commonly known as "alcohol") in engines is one of the current research hotspots. At present, there are two main technical routes for the research or promotion of ethanol in vehicle engines at home and abroad . [0003] One is ethanol gasoline (blending) technology. The main features of this technology are: ①The purity of ethanol is required to be no less than 99.5%. The production cost of ethanol is very high and a large amount of greenhouse gases (CO 2 ); ② ethanol and gasoline are mixed in proportion to form ethanol gasoline with different ethanol contents such as E10 (the proportion of ethanol is 10% (V / V)). Although this technology is re...
