Abstract

The invention relates to an oxygen direct-injection pure-hydrogen combustion engine and a power system thereof. The oxygen direct-injection pure-hydrogen combustion engine comprises a hydrogen fuel engine body, a magnesium hydride storage tank, a pressure swing adsorption oxygenerator, a three-way catalyst, a tail gas waste heat utilization unit and a hydrogen purification unit. The magnesium hydride storage tank is connected to a hydrogen opening of the hydrogen fuel engine body through a low-pressure hydrogen buffering tank, and the pressure swing adsorption oxygenerator is connected to an oxygen nozzle of the hydrogen fuel engine body through a high-pressure oxygen buffering tank. Exhausting holes of the hydrogen fuel engine body are connected to the three-way catalyst through a tail gas expander or a turbocharging unit, and an outlet of the three-way catalyst is connected to a gas-liquid separator through a kelaipu unit / combined type kelaipu unit. A gas outlet of the gas-liquid separator is connected to a steam inlet of the magnesium hydride storage tank through the hydrogen purification unit, and a water outlet of the gas-liquid separator is connected to a cooling water tank.The oxygen direct-injection pure-hydrogen combustion engine is combined with the kelaipu unit / combined type kelaipu unit through the hydrogen fuel engine body, tail gas waste heat of the engine body is fully utilized, and the heat efficiency of the engine body is improved.

Description

technical field [0001] The invention belongs to the technical field of new energy engines, and relates to an energy-saving and environment-friendly oxygen direct injection pure hydrogen combustion internal combustion engine 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 stringen...
