Abstract

The invention relates to an oxygen direct injection pure hydrogen combustion engine and its power system, including a hydrogen fuel engine, a magnesium hydride storage tank, a pressure swing adsorption oxygen generator, a three-way catalytic converter, a tail gas waste heat utilization unit, and a hydrogen purification unit. The magnesium hydride storage tank is connected to the hydrogen port of the hydrogen fuel engine through a low-pressure hydrogen buffer tank, and the pressure swing adsorption oxygen generator is connected to the oxygen nozzle of the hydrogen fuel engine through a high-pressure oxygen buffer tank. The exhaust hole of the hydrogen fuel engine is connected to the three-way catalytic converter through the exhaust gas expander or turbocharger unit, and the outlet of the three-way catalytic converter is connected to the gas-liquid separator through the Clep unit / compound Clapp unit. The gas outlet of the gas-liquid separator is connected to the water gas inlet of the magnesium hydride storage tank through the hydrogen purification unit, and the water outlet of the gas-liquid separator is connected to the cooling water tank. The invention combines the hydrogen fuel engine with the Clapp unit / composite Clapp unit, fully utilizes the waste heat of the exhaust gas of the engine, and improves the thermal efficiency of the engine.

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...
