Embodiment 1

[0024] After Ni is melted in a vacuum induction furnace, La is added under the protection of argon with a pressure of 0.03MPa, and when all the materials are melted, it is poured to make LaNi. 5 hydrogen storage alloys;

[0025] After the hydrogen storage alloy is mechanically crushed, it is placed in the hydrogen storage tank and filled, and the hydrogen gas is introduced into the hydrogen storage tank with a hydrogen cylinder; the time for the first filling of hydrogen gas is 30~50h, and the hydrogen storage alloy is activated during this process. Automatically crushed into fine particles; when hydrogen is charged again later, the time is controlled at 0.5~2h to reach 50~80% of the total hydrogen absorption capacity of the hydrogen storage alloy; after the completion of hydrogen charging, the equilibrium hydrogen pressure of the hydrogen storage alloy in the hydrogen storage tank is at 0.1~0.5MPa;

[0026] Assemble the filled hydrogen storage tank, hydrogen pipeline, oil pu...

Embodiment 2

[0034] The hydrogen storage alloy is the same as in Example 1; the method of filling hydrogen is the same as in Example 1; the hydrogen storage tank after hydrogen charging, the hydrogen pipeline, the oil pump relay of the fuel vehicle and the intake manifold of the engine are assembled together, and the method is the same as in the example 1. The difference lies in:

[0035] The hydrogen storage tank is made of steel;

[0036] The hydrogen pipeline is stainless steel pipe;

[0037] The flow controller selects the control hole;

[0038] The application method is the same as in Example 1, except that the flow rate of hydrogen in the hydrogen pipeline is controlled to be 200mL / min;

[0039] A car equipped with a gasoline engine was used for the test, and the driving distance was 496 kilometers. Compared with the traditional method without hydrogen, the gasoline was saved by 14%, and the total emissions of carbon monoxide, carbon dioxide, hydrocarbons and suspended particles we...

Embodiment 3

[0041] Vacuum melting to make MmNi 5 Hydrogen storage alloy (Mm is mixed rare earth);

[0042] The hydrogen storage alloy is mechanically crushed and placed in the hydrogen storage tank to fill it up, the method is the same as in Example 1; the hydrogen storage tank after hydrogen filling is assembled with the hydrogen pipeline, the oil pump relay of the fuel vehicle and the engine intake manifold, and the method is as follows: With embodiment 1, difference is:

[0043] The hydrogen storage tank is made of resin reinforced metal material;

[0044] The flow controller selects the control hole;

[0045] The application method is the same as in Example 1, except that the flow rate of hydrogen in the hydrogen pipeline is controlled to be 100mL / min;

[0046]A medium bus equipped with a diesel engine was used for the test, and the driving distance was 496 kilometers. Compared with the traditional method without hydrogen, the diesel fuel was saved by 13%. The emission tester was u...

Abstract

The invention discloses an oil-saving emission reduction device of a gasoline-powered automobile and an application method thereof. The device is composed of a hydrogen store tank, a valve and a hydrogen pipeline, wherein a hydrogen storage alloy is arranged in the hydrogen store tank, and the lower end of the valve is provided with a cellular material filter; an electromagnetic valve and a flow controller are serially connected in the hydrogen pipeline, and the electromagnetic valve is connected with an oil pump relay of an engine; one end of the hydrogen pipeline is connected with the hydrogen store tank through the valve, and the other end of the hydrogen pipeline is connected with an inlet manifold of the engine; the application method comprises the following steps: when the engine is opened, the electromagnetic valve of the hydrogen pipeline is opened along with the oil pump of the engine, and the hydrogen released by the hydrogen storage alloy in the hydrogen store tank is mixed with the gas of an air inlet pipe through the inlet manifold of the engine so as to enter a combustor of the engine to support combustion of a fuel oil. The emission reduction device provided by the invention has the advantages of being capable of saving the fuel oil by 5-22%, obviously reducing discharging smoke, and increasing the power output of the automobile, reducing the use cost of the gasoline-powered automobile; and the hydrogen stored by the hydrogen storage alloy can be reused by filling hydrogen again after being completely used.

Description

technical field [0001] The invention relates to a fuel-saving and emission-reducing method for automobiles, in particular to a fuel-saving and emission-reducing device for fuel automobiles and an application method thereof. Background technique [0002] Currently, saving energy and reducing emissions has become the focus of worldwide attention. The annual consumption of fuel oil in our country has exceeded 200 million tons. It is of great significance to save fuel oil and reduce harmful gas emissions. The use of hydrogen as a fuel has always been a sought-after goal, because hydrogen has a higher combustion value compared with fuel oil, and there is no harmful substance emission at all. Hydrogen-fueled vehicles have been under development at home and abroad, including vehicles using hydrogen storage alloys, high-pressure hydrogen or liquid hydrogen as hydrogen sources, vehicles powered by fuel cells, and fuel / hydrogen hybrid vehicles. These vehicles that use hydrogen as th...
