Problems solved by technology

However, due to the application effect of many types of related products developed on the engine's power and economy, the difference between the positive and negative ratios does not meet the actual application requirements (the actual application technical index is too low), and the key problem has not been broken so far. technical difficulties
In addition, three-way catalytic converters, exhaust gas mufflers and purifiers currently on the market, PCV ventilation valves recommende

Embodiment 1

[0021] The composition of the multi-element precious rare alloy formula of the sponge body is: (calculated by parts by weight)

[0022] 45 parts of tin; 13 parts of lead; 5.0 parts of bismuth; 5.0 parts of zinc; 4.0 parts of antimony;

[0023] 20 parts of indium; 7.0 parts of gallium; 0.5 parts of platinum; 0.3 parts of palladium; 0.2 parts of rhodium;

[0024] The alloy particle size of the components of this formula is 0.1 μm. When the internal combustion engine adopts this formula, the technical indicators of power and economy are higher, but the technical indicators of emission performance and durability are lower.

Embodiment 2

[0026] The composition of the multi-element precious rare alloy formula of the sponge body is: (calculated by parts by weight)

[0027] 30 parts of tin; 20 parts of lead; 5.0 parts of bismuth; 5.0 parts of zinc; 5.0 parts of antimony;

[0028] 20 parts of indium; 13 parts of gallium; 0.9 parts of platinum; 0.7 parts of palladium; 0.4 parts of rhodium;

[0029] The particle size of the components in this formula is 0.01 μm. When the internal combustion engine adopts this formula, the technical indicators of durability and emission are higher, but the technical indicators of power and economy are lower.

Embodiment 3

[0031] The composition of the multi-element precious rare alloy formula of the sponge body is: (calculated by parts by weight)

[0032] 35 parts of tin; 20 parts of lead; 5.0 parts of bismuth; 5.0 parts of zinc; 5.0 parts of antimony;

[0033] 15 parts of indium; 12 parts of gallium; 1.5 parts of platinum; 1.0 parts of palladium; 0.5 parts of rhodium;

[0034] The particle size of the components of this formula is 0.5-100nm. When the internal combustion engine adopts this formula, the comprehensive technical indicators such as power, economy, durability and emission can all reach the highest value.

Abstract

The invention is a sponge multielemnet rare precious alloy and its use, a nano powdery alloy mixture combined with Sn, Pb, In, Ga, Bi, Pt, Zn, Pd, Sb, Rh, and other metals, and its fineness 0.1 mum-100 nm. It is mainly used in different types of internal-combustion engines. As the content of Sn, Pb, Bi, Zn and Sb is 5-60% of the total weight, the power and economic technical indexes of the internal-combustion engines reach the optimum state, as the content of In and Ga is 5-30%, the duability reach the optimum state, as the content of Pt, Pd, and Rh is 0.1-1.5%, the discharge property reach the optimum state. It can also be applied to various machineries, acting as a lubricating combination for driving components, has excellent antwearability and corrosion resistance and can protect the surface layer of the driving components.

Description

technical field [0001] The present invention relates to a non-ferrous alloy composition, in particular to a synthetic composition containing tin, indium, lead, gallium, bismuth, platinum, zinc, palladium, antimony, rhodium and other multiple noble and rare alloys, but the weight of each component Powdered alloy materials with less than 50% (international classification codes are C22C / 1 / 00 and C22C / 30 / 00). It is mainly used for the anti-wear of various internal combustion engine cylinders and pistons in the boundary friction and the internal combustion engine under normal operating conditions, to compensate for the wear marks produced by the natural wear parts between various parts and to improve the combustion conditions of the internal combustion engine. Background technique [0002] Various types of internal combustion engines (including railway diesel locomotives, various land fuel vehicles, water transport ship facilities and various engineering internal combustion engin...
