Abstract

The invention relates to a hydrogen fuel engine protection system. The hydrogen fuel engine protection system comprises a hydrogen fuel engine, a high-pressure air pipeline, a fuel gas pipeline, a waste gas pipeline, an engine oil circulating pipeline, a cooling water circulating pipeline, a protection shell, a fuel pipeline protection casing and a waste gas pipeline protection casing. The hydrogen fuel engine is wrapped with the protection shell. A hydrogen storing unit is connected with the fuel gas pipeline through a fuel valve. A protection gas interlayer is formed between an engine shell of the hydrogen fuel engine and the protection shell. A protection gas storage tank communicates with the fuel pipeline protection casing through a valve. The fuel pipeline protection casing and the waste gas pipeline protection casing communicate with the protection gas interlayer, and pipeline connection sealing rubber sleeves are arranged at the joints. The protection gas interlayer is provided with a protection gas outlet which is connected to the fuel pipeline protection casing. By arranging the protection shell outside the engine, protection gas is used for protecting the engine, and leakage of hydrogen is reduced and even avoided; and the operation safety of the engine is advantageously protected, and unnecessary disasters are avoided.

Description

technical field [0001] The invention belongs to the technical field of engines and relates to a hydrogen fuel engine, in particular to a hydrogen fuel engine protection system. Background technique [0002] A traditional fuel engine burns hydrocarbons and oxygen in the air in the cylinder of the engine and converts the heat energy generated by the combustion into mechanical energy, emitting CO2 and harmful pollutants. The hydrogen fuel engine converts the heat energy generated by combustion into mechanical energy through the combustion of hydrogen and oxygen, and the emission is water, so it can be called the "cleanest" engine. When the engine is fueled by pure hydrogen, it can achieve zero greenhouse gas emissions. In order to protect the environment and reduce air pollution in cities, engines fueled by hydrogen have attracted more and more attention. [0003] Due to the small molecular weight of hydrogen, it is easy to escape from narrow gaps, the structure of the engine ...
