Abstract

The invention designs a control method of a non-tempering hydrogen-ammonia dual-fuel zero-carbon rotor machine, and specifically relates to a control method for eliminating the tempering problem of a hydrogen rotor machine by combusting two fuels of hydrogen and ammonia. The invention uses the engine speed sensor and the intake pressure sensor as signals to judge the operation of the rotor machine, select the hydrogen ammonia blending ratio suitable for the current working condition to suppress the occurrence of no backfire phenomenon, and realize the high power and high safety zero Carbon emission rotor machine.

Description

technical field [0001] The invention designs a control method for a non-tempering hydrogen-ammonia dual-fuel zero-carbon rotor machine, in particular to a control method for eliminating the tempering problem of a hydrogen rotor machine by combining two fuels, hydrogen and ammonia, and belongs to the field of internal combustion engines. Background technique [0002] With the massive emission of greenhouse gases, it has caused many negative impacts on the global climate. Climate problems caused by greenhouse gas emissions such as global warming and melting glaciers have seriously affected the normal life of people in the world. In particular, the transportation industry is a global Therefore, how to reduce carbon emissions in the transportation industry has become an important issue to be solved urgently. Hydrogen is a kind of renewable energy that does not contain carbon elements, and its combustion does not produce carbon emissions, so it is an excellent alternative fuel, b...
