Description

technical field [0001] The invention belongs to a device for improving the combustion of an internal combustion engine by utilizing the waste gas of the internal combustion engine, in particular to a device for improving the combustion of the internal combustion engine by using the energy of the exhaust gas of the internal combustion engine to electrolyze water to generate hydrogen. Background technique [0002] Hydrogen has a catalytic effect on the hydrocarbon fuel of the internal combustion engine, shortens the ignition delay period, and has a fast flame propagation speed, which makes the internal combustion engine burn completely, achieves the purpose of saving energy and reducing harmful emissions, and the effect is remarkable. For example, gasoline engine, after adding hydrogen, the thermal efficiency of partial load can be increased by 7% to 15%, the fuel consumption of gasoline at low load is reduced by about 20% to 25%, the CO emission is reduced to 1 / 4 of that of pu...

Problems solved by technology

[0008] Electrolysis of water to generate hydrogen is a convenient method of providing hydrogen, which can be used in vehicles without storage problems, but electrolysis of water needs to consume a considerable amount of electricity to produce 1NM 3 Hydrogen requires more than 4KW of electric energy. If the electric energy of the battery or generator on the vehicle (provided by the effective work of the internal combustion engine) is used, the energy saving effect is poor due to the consumption of a large amount of effective work of the internal combustion engine, which weakens the effect of hydrogen-mixed combustion and limits the efficiency of hydrogen-mixed combustion of electrolyzed water.
