A hydrogen fuel engine protection system

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, relates to a hydrogen fuel engine, and specifically relates to a hydrogen fuel engine protection system. Background technique [0002] Traditional fuel engines burn hydrocarbons and oxygen in the air in the engine cylinder and convert the heat energy generated by combustion into mechanical energy, emitting CO2 and harmful pollutants. The hydrogen fuel engine converts the thermal energy generated by combustion into mechanical energy through the combustion of hydrogen and oxygen. The emission is water, so it can be called the "cleanest" engine. When the engine uses pure hydrogen as fuel, it can achieve zero emission of greenhouse gases. In order to protect the environment and reduce air pollution in cities, engines using hydrogen as fuel have received more and more attention. [0003] Due to the small molecular weight of hydrogen, it is easy to escape from small gaps. The engine structure is compl...

AI Technical Summary

Problems solved by technology

[0003] Due to the small molecular weight of hydrogen, it is easy to escape from narrow gaps, the structure of the engine is complex, and there are many connection points with external pipelines and components, which is prone to leakage

The leakage of fuel into the atmosphere in the hydrogen fuel engine is not only not conducive to environmental protection, but also prone to serious problems of fire
