Environment protection hydrogen preparing and supplying method for vehicle and hydrogen engine

Abstract

The invention relates to a vehicle environment-protective hydrogen preparation supply method and a hydrogen engine. The invention is characterized in that the invention is carried out according to the following steps: first, H2 is produced by pure water, the purity of the H2 reaches more than 99.9 percent, P of the H2 equals 0.4Mpa, the H2 passes through a first gas storage tank, a second gas storage tank and a third gas storage tank, then the H2 is compressed by a compressor, the compressor can produce H2 the P of which equals 30Mpa, and at last the H2 is delivered to the gas storage tank of a transporter by a gas filling machine which can produce H2 the P of which equals 30Mpa; second, the gas storage tank is transported to a gas filling station, a gas outlet of the gas storage is connected with a gas transporting pipeline, the H2 passes through an H2 desiccator through the gas transporting pipeline to eliminate moisture in H2 gas, then the H2 goes into the gas storage tank, then the H2 goes into the compressor which produces H2 the P of which equals 30Mpa from an output of the gas storage tank to be compressed, at last the H2 is delivered to the gas filling machine which produces H2 the P of which equals 30Mpa, and H2 fuel is added to the a fuel tank of a vehicle by the gas filling machine. The method not only can supply H2 energy to a car as power, but also is environment protective and has great available resources, has little cylinder body and cylinder cover steel plate welding stamping molding process, has strong rigidity, and is durable.

Description

Technical field: [0001] The invention relates to a method for preparing and supplying environment-friendly hydrogen for vehicles and a hydrogen engine. Background technique: [0002] At present, the gas used for automobiles is mainly liquefied petroleum gas (LPG) and natural gas (CNG, LNG), which have a high octane number and excellent anti-knock performance. They are used in gasoline engines with high compression ratios, which can increase the power of the engine and reduce Fuel consumption; has good evaporation and combustion properties, can ensure smooth engine operation, complete combustion, and less carbon deposits; has good safety, and is not prone to early oxidative deterioration during storage, transportation and use, which is harmful to engine components and The oil storage container is non-corrosive. However, it is a flammable and explosive product with low toxicity. Its toxicity increases with the increase of olefin content, sulfur content and aromatic hydrocarbo...

AI Technical Summary

Problems solved by technology

However, it is a flammable and explosive product with low toxicity. Its toxicity increases with the increase of olefin content, sulfur content and aromatic hydrocarbon content. The main invasion routes are steam inhalation, ingestion, skin and eye contact; the flash point is below 0C, and the spontaneous ignition point is at Within the range of 415C ~ 530C, under normal ambient temperature, it may cause combustion or explosion when encountering an open flame. Its vapor and air are easily mixed to form explosive gas, and the explosion limit is 1.4% ~ 7.6% (V / V). In addition, oil resources are decreasing day by day. Therefore, there is an urgent need for alternatives to vehicle energy
