The liquid hydrogen and liquid oxygen direct injection piston type internal combustion power system can be used for power generation, and can also be used for power output.

Description

technical field [0001] The application belongs to the technical field of new energy engines, and in particular relates to a liquid hydrogen and liquid oxygen direct injection piston type internal combustion power system. Background technique [0002] Energy shortage, environmental pollution, and global climate change make it urgent to develop clean, efficient, safe and sustainable energy, among which hydrogen energy is being valued by more and more countries. In the 21st century, the engine industry has developed rapidly, but gasoline engines and diesel engines are still the main types of vehicle engines. Both gasoline and diesel are non-renewable resources. In order to alleviate a series of negative effects brought about by the scarcity of petroleum resources and reduce air pollution and engine exhaust emissions, it is necessary to find alternative fuels for engines, and hydrogen energy is currently the most ideal clean fuel. With the increasingly stringent environmental p...
