Problems solved by technology

At present, the commonly used method to reduce emissions is to install a precious metal catalytic device on the exhaust gas passage to convert harmful gases into harmless gases, but it is expensive, easy to poison, and has a short service life. Although it has been exploring the use of rare earth alloys to replace or partially replace precious metals , but it is not ideal in terms of effect and life; at the same time, adding certain substances to diesel to improve combustion efficiency will cause damage to the engine; the effects of some nano fuel economizers, environmental fuel economizers and other products have yet to be verified

Embodiment 1

[0021] Alloy composition weight percent is as shown in Table 1:

[0022] Table 1 Alloy composition weight percentage (%)

[0023] Ni Cu Zn sn co Gd 23.3 54.8 14.1 2.3 5.0 0.5

[0024] Use a vacuum induction furnace to melt the alloy under vacuum conditions, fill it with Ar when adding low-melting point metals, melt it under the protection of Ar gas, and make alloy particles by crushing and ball milling. The particle size is between 2 and 5mm, and then Alloys are placed in a fuel saver container.

[0025] The fuel consumption test of the fuel-saving and emission reducer was carried out on a high-pressure common rail diesel engine. Connect the alloy fuel-saving and emission reducer in series to the oil inlet pipeline in front of the filter, select the speed as 1650r / min, according to the maximum torque of 10%, 25%, 40%, 50%, 60%, 75%, 90%, 100% eight load points, adjust the torque value at a constant speed, and measure the fuel consumption per...

[0031] Ni Cu Zn sn co La+Ce Ti B 18.5 66.5 7.7 3.5 2.3 0.7 0.7 0.10

[0032] After the alloy is smelted in a vacuum induction furnace under the protection of Ar gas, it is processed into a porous sheet (such as figure 1 shown), put in the fuel-saving and emission-reducing device ( figure 2 ), connected in series to the oil inlet pipeline before the diesel engine filter.

[0033] Use hydraulic dynamometer and CC6102 diesel engine to test the effect of fuel saving and emission reduction. The comparative data is the measured data without installing the fuel-saving and emission-reducing device. The fixed speed of the engine is 1000r / min, and the torque of 5, 10, 15, 20, 25, 30, 35, 40kg is selected for the dynamometer respectively, and the fuel consumption in the time interval of 30s is measured; Smoke sampling measu...

[0038] Table 5 Alloy composition weight percentage (%)

[0039] Ni Cu Zn sn co La+Nd Ti 14.6 46.9 30 5.6 1.6 1.0 0.3

[0040] The alloy is smelted in a vacuum induction furnace, which is first smelted in a vacuum state and filled with Ar gas before adding low melting point metals. After pouring, it is processed into a porous rod with grooves and inner holes, and it is made into a fuel-saving and emission-reducing device connected in series to the oil inlet pipeline in front of the diesel engine filter of a light truck (produced in 1996) for road test (fixed distance round-trip driving ). The fuel consumption per 100 kilometers is shown in Table 6:

[0042] Emission test data is shown in Table 7 (each value is the average of 4 tests):

[0043]

[0044] It can be seen from the test results that the fuel saving rate is about 3%, and the emission reduction rate ...

Abstract

The purpose of the present invention is to provide a special alloy that can be used for fuel saving and emission reduction of diesel engines and its application method. It uses the electrostatic catalytic activity of the alloy to disperse the macromolecular groups in the fuel oil to achieve fuel saving and emission reduction. Purpose. The alloy only plays a catalytic role during use and does not consume itself. The special alloy can be used for a long time, and is convenient to use and low in price. In addition to energy saving, its most important feature is to significantly reduce the smog emissions of diesel vehicles.

Description

technical field [0001] The invention relates to fuel-saving and emission-reducing technologies for diesel engines, in particular to a special alloy with fuel-saving and emission-reducing functions and its application. Background technique [0002] Currently, saving energy and reducing emissions has become the focus of worldwide attention. The annual consumption of diesel in my country has exceeded 120 million tons. It is of great significance to save the fuel consumption of diesel engines and reduce harmful gas emissions. The combustion of diesel oil is an oxidation process. If the chains of hydrocarbon macromolecules entangled in the fuel can be dispersed before entering the engine combustion chamber, it will help the fuel molecules to fully contact with oxygen, thereby improving combustion efficiency and reducing the amount caused by Harmful gas emissions from incomplete combustion. At present, the commonly used method to reduce emissions is to install a precious metal c...
