[0002] In the prior art, the current diesel engine mainly converts the heat energy generated by the combustion of diesel, a non-renewable fossil energy, into mechanical energy output. During the power stroke of the diesel engine, due to the incomplete combustion of fossil energy, it is very easy to produce carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx) and particulate emissions and other harmful products that are not conducive to the environment. Therefore, the emission performance of traditional diesel engines is poor and the damage to the environment is relatively large. Utility Model Content

[0010] Compared with the prior art, the advantages and positive effects of the utility model are:

[0011] The utility model supplies the generated hydrogen into the cylinder of the engine and mixes it with diesel to burn and do work. Since the combustion rate of hydrogen is higher than that of diesel, the hydrogen can be quickly ignited and the diesel can be quickly ignited after compression ignition, thereby improving the combustion performance, enabling the diesel to be quickly ignited and fully burned, thereby reducing the generation of harmful substances, improving the emission performance of the engine, and being beneficial to environmental protection; at the same time, the combustion product of hydrogen is only water, which will not pollute the environment; in addition, hydrogen is used to enable the diesel to be quickly ignited and fully burned, and under the condition of outputting the same power, the injected diesel fuel is reduced, thereby improving the fuel economy of the diesel engine.

[0016] Example 1

[0017] like Figure 1As shown, the utility model provides a technical solution: a hydrogen supply mechanism for a diesel engine, comprising: a shell body 1, the shell body 1 comprises a left shell body 11, a water inlet 13 is provided on one side of the left shell body 11, one side of the water inlet 13 and one side of the oxygen outlet 14 are both connected to one side of the working chamber 61, one side of the hydrogen outlet 15 is connected to the other side of the working chamber 61, an oxygen outlet 14 is provided on one side of the left shell body 11, a first insulating sheet 5 is provided on one side of the left shell body 11, a positive electrode sheet 2 is provided on one side of the first insulating sheet 5, the positive electrode sheet 2 is provided between the first insulating sheet 5 and the second insulating sheet 6, a positive electrode potential connection 21 is provided on one side of the positive electrode sheet 2, and a first positive electrode potential connection 21 is provided on the other side of the positive electrode sheet 2 Two insulating sheets 6, a working chamber 61 is provided on one side of the second insulating sheet 6, a screening element 4 is arranged on one side of the second insulating sheet 6, the screening element 4 is arranged between the two second insulating sheets 6, the screening element 4 is used to allow hydrogen ions to pass unidirectionally from the positive electrode sheet 2 to the negative electrode sheet 3 and isolate the passage of oxygen and hydrogen, a negative electrode sheet 3 is arranged on one side of the screening element 4, a second insulating sheet 6 identical to one side of the screening element 4 is arranged on the other side of the negative electrode sheet 3, the negative electrode sheet 3 is arranged between the second insulating sheet 6 and the third insulating sheet 7, a negative electrode potential 31 is arranged on one side of the negative electrode sheet 3, a third insulating sheet 7 is arranged on the other side of the negative electrode sheet 3, a right shell 12 is arranged on one side of the third insulating sheet 7, and a hydrogen outlet 15 is arranged on one side of the right shell 12.

[0018] Working principle:

[0019] like Figure 1As shown, the water inlet 13 supplies water into the hollow working chamber 61 of the second insulating sheet 6, so that the positive electrode sheet 2 and the negative electrode sheet 3 are in contact with the water, and current is passed through the positive electrode sheet 2 and the negative electrode sheet 3, so as to electrolyze the water. Since the screening element 4 allows water to pass through and only allows hydrogen ions to pass in a unidirectional direction from the positive electrode sheet 2 to the negative electrode sheet 3, during the electrolysis process, the hydrogen ions move toward the negative electrode sheet 3 and obtain electrons around the negative electrode sheet 3 to generate hydrogen, while the hydroxide ions move toward the positive electrode sheet 2 and lose electrons around the positive electrode sheet 2 to generate oxygen. In addition, the isolation of the screening element 4 can also prevent the hydrogen and oxygen from mixing, so that the oxygen is discharged through the oxygen outlet 14, and the hydrogen is discharged through the hydrogen outlet 15 and enters the intake pipe of the engine, thereby allowing the hydrogen to enter the cylinder of the engine, and the generated hydrogen is supplied to the cylinder of the engine and mixed with the diesel for combustion. Because the combustion rate of hydrogen is higher than that of diesel, hydrogen can be quickly ignited after compression ignition and the diesel can be quickly ignited, which improves the combustion performance and enables the diesel to be quickly ignited and fully burned, thereby reducing the generation of harmful substances, improving the emission performance of the engine and being environmentally friendly; at the same time, the combustion product of hydrogen is only water, which will not pollute the environment; in addition, hydrogen is used to make the diesel quickly ignite and fully burn, and under the condition of outputting the same power, the injected diesel fuel is reduced, thereby improving the fuel economy of the diesel engine. In order to improve the emission performance of the diesel engine, be environmentally friendly and improve the fuel economy of the diesel engine, hydrogen can also be stored in a storage bottle, and the stored hydrogen can be released into the intake pipe of the engine when the diesel engine is working, so that the hydrogen enters the cylinder of the engine to participate in combustion.
