Description

Combustion fuel-saving device for diesel engine and diesel engine energy-saving system

Technical field

Background technique

As a power equipment to promote the development of modern society, diesel engines are indispensable, and their fields are very extensive. They have been widely used since the industrial age. However, due to the high level of fuel consumption, exhaust emissions have a greater impact on the natural environment, which is currently the focus of energy conservation and emission reduction.

In this context, a variety of diesel fuel savers on the market have been introduced. For example, the “volute fuel saver” adopts dual treatment technology, namely magnetization technology and heating technology, and has the advantage of making full use of engine waste heat and achieving certain results. However, its shortcoming is that it is heated by cooling water. When the heat of the cooling water is taken away, the water temperature will be too low, which will affect the normal operation of the engine, reduce the working efficiency and increase the fuel consumption. Second, in the winter or in the north, due to the extremely low temperature, the viscosity of the diesel oil is large and the heating is difficult, which is not conducive to starting. The “Weibiling” fuel-saving device changes the gas structure on the diesel engine air supply system to promote the full combustion of the diesel fuel in the combustion chamber. The advantage is that the exhaust gas is reduced and the engine work is increased. The disadvantage is that the use of chemical reaction technology, containing acid and alkali components, will corrode the engine, the longer the damage to the engine. In the past few years, the US “fuel-efficient king”, which is popular in the market, is installed on the diesel circuit to magnetize diesel to improve combustion efficiency. The main disadvantage is that diesel is not fully magnetized, especially in high-power engines, where the oil supply is large. The oil has a fast flow rate, so it does not achieve good results.

Embodiments of the invention

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The invention makes a cutting movement of the diesel molecules through a strong magnetic field, so that the fuel molecules undergo structural changes, and the cluster molecules become the chain molecules which are more easily burned.

1, 2, and 3 show the structure of a combustion-supporting economizer for a diesel engine provided by an embodiment of the present invention. Referring to Figures 1, 2 and 3, the combustion-assisted fuel-saving device is an internal hollow container having an oil inlet port 1 and an oil outlet port 2, and the magnetized region 3 is located between the oil inlet port 1 and the oil outlet port 2 The diesel oil is injected from the oil inlet port 1 and passes through the magnetization region 3, and then flows out from the oil outlet port 2.

A magnet is disposed on each of the opposite outer sides of the magnetized region 3, and the sides of the magnets adjacent to the magnetized region have opposite polarities, such as a side of the magnet adjacent to the magnetized region 3 being an N pole, and the other magnet and the magnetized region 3 The adjacent side is the S pole, so that magnetic lines of force pass through the magnetized region 3. When diesel fuel flows inside the magnetized region 3, the diesel molecules are cut by magnetic lines of force, and the oil molecules are magnetized into a chain shape, and the magnetized diesel molecules are arranged in an orderly manner, and the fluidity is stronger, thereby achieving excellent atomization and burning. Thoroughly, the long engine life of the engine reduces exhaust emissions.

In order to ensure sufficient magnetization of the diesel molecules, the two magnets can be respectively designed to be composed of a plurality of elongated magnetic strips. The magnetic properties of the small magnetic strips are more concentrated than those of the large magnets, as shown in Fig. 2 and Fig. 3, Fig. 2 The magnet in the middle includes a plurality of magnetic strips 4, and the magnet in Fig. 3 includes a plurality of magnetic strips 5, and the long sides of the magnetic strips 4 and the magnetic strips 5 are arranged perpendicular to the direction of the diesel flow, which contributes to the magnetic field lines of the diesel and magnetized regions. At a ninety degree angle, the diesel molecules flowing through the magnetized region 3 are sufficiently magnetized, and the plurality of magnetic strips 4 and the magnetic strips 5 can form a mesh magnetic line of the closed cuttable diesel molecules to maximize the magnetization of the diesel molecules. Further, the magnetic strip 4 and the magnetic strip 5 described above can be realized by a small size, light weight and strong magnetic NdFeB magnetic strip.

Further, in order to ensure that the diesel molecules flowing through the magnetized region 3 can be magnetized, in the embodiment, the magnetized region 3 is designed to have a flat shape with a height of no more than 3 mm, so that the diesel fluid in the magnetized region 3 is not too thick. As a result, the magnetization of the diesel molecules in the middle is insufficient.

Further, in order to extend the magnetization time of the diesel molecules in the magnetized region 3, the magnetized region 3 is a rectangular region whose long side is parallel to the direction of the diesel flow direction, that is, the connection direction with the oil inlet port 1 and the oil outlet port 2 parallel.

In order to avoid the retention of the diesel oil passing through the magnetized region 3, and ensuring the smooth flow of the oil passage, the four corners of the magnetized region 3 are treated with a rounded edge to form a circular chamfer.

In order to avoid excessive diesel pressure, the flow rate in the fuel-saving device is too fast, resulting in insufficient magnetization. Especially in the position of the inlet port 1 and the outlet port 2, a buffer 6 and a buffer 7 for limiting the diesel flow rate are respectively provided, and the buffer zone is provided. Both the 6 and the buffer zone 7 are in communication with the magnetized region, and the diesel fuel can smoothly pass through the magnetized region 3 and reach the buffer zone 7 after being buffered by the buffer zone 6. As shown in FIG. 1, the buffer zone 6 and the buffer zone 7 can be designed in the shape of a column, which are respectively located below the oil inlet port 6 and the oil outlet port 7, and can of course be disposed on the side of the oil inlet port 6 and the oil outlet port 7, The specific limit is not limited, and the current limit can be realized.

The magnetic strip 4 and the magnetic strip 5 magnetic strip are detachable at the outside of the fuel-saving device, and there is no need to worry about residual metal impurities remaining inside the fuel-saving device under the action of a magnetic field. And when the magnetic strip is magnetized by other strong magnetic fields to cause the magnetic force to drop, it can be detached and re-magnetized for reuse.

The combustion-supporting fuel-saving device is recommended to be made of 316 stainless steel material, which has the advantages of not attenuating magnetic lines and magnetic field strength, acid and alkali resistance, corrosion resistance, high temperature resistance and oil resistance.

Tests have shown that when the magnetic stripe 4 and the magnetic strip 5 of opposite polarities on opposite sides of the magnetized region 3 form a magnetic induction intensity in the magnetized region 3 below 3500 Gauss (GS), the fuel economy rate is not significantly improved. When the magnetic induction intensity is 3500 Gauss, the fuel saving effect is more significant, and when the magnetic induction intensity is 6000 Gauss, the fuel saving effect is the best. The specific test data is shown in Figure 4 below. The data in Figure 4 is fixed at ambient temperature. 32 degrees, the engine running water temperature to 55 degrees, engine power 300KW, load rate of 80% of the bench laboratory to test, through the original engine oil consumption and fuel economy fuel consumption comparison test. From the test data in Figure 4 above, it can be seen that the range of magnetic induction can be selected between 3500---6000 Gauss, and 3500---4300 Gaussian starts to have significant effect, if it is higher in terms of economic value. The fuel economy rate is suitable at 4300---6000 Gauss, of which 5000---6000 Gauss has the best effect, but after 6000 gauss, the fuel-saving effect does not change much.

The invention also provides a diesel engine energy-saving system, comprising a diesel fuel tank, a filter, a diesel engine, a combustion-supporting fuel-saving device for a diesel engine as described above, a diesel engine with an oil pump, and a combustion-supporting fuel-saving device The oil inlet 1 is connected to the oil tank through the filter, and the oil outlet 2 of the combustion-supporting fuel-saving device is connected to the oil inlet of the diesel engine. Wherein, the oil outlet 2 of the combustion-supporting fuel-saving device and the diesel engine can be connected by a soft oil pipe to prevent vibration, for example, an acid-base and high-temperature resistant imported material can be used.

It has been found that a heating device connected between the engine and the combustion-supporting fuel-saving device can be further provided, and the oil is smoothed by heating the diesel oil in the pipeline to directly evaporate the moisture in the oil and improve the magnetization effect. Specific heating devices can be used in the following ways:

First, the electric energy heating device: the heating time is short, the electric energy conversion rate is high, for example, heat pump, heat, electromagnetic heating, and the like.

Second, engine exhaust pipe waste heat recovery device: This is an environmentally friendly and economical heating method, which makes full use of the high temperature heat of the engine exhaust pipe, through the process of thermal energy absorption → heat exchange → temperature regulation → output to achieve the desired effect. On the one hand, it can be used for energy-saving renovation, on the one hand to provide convenience to the crew.

Third, the heat exchanger: This is the use of water tank hot water energy treatment technology, through the heat exchanger and the water tank connection for thermal energy conversion, recycling.

Tests have shown that when the heating temperature of diesel is 60-75 degrees, the fuel-saving effect can be improved without adding a magnetic field. If it is lower than this range, there may be no improvement or improvement, but above this range. It is possible to make structural changes in the diesel molecules. The specific test data is shown in Figure 5 below. The data in Figure 5 is fixed in a bench laboratory with an ambient temperature of 32, engine operating water temperature of 55 degrees, engine power of 300 kW, load factor of 80%, and magnetic induction of 0 gauss. According to the comparison between the original engine oil consumption and the energy consumption of the fuel-saving device.

In the laboratory bench test, the magnetic induction intensity and heating temperature were simultaneously tested. The test results showed that the oil temperature was controlled by 60-75 °C, the magnetic induction intensity was controlled by 5000-6000 GS, and the fuel-saving rate was measured to be 6.2-7% or more. Very significant, with high economic value, the specific data shown in Figure 6.

In addition, it is also possible to directly use the heat of the engine oil return to match the magnetization to achieve the purpose of fuel saving without additionally providing a heating device. In this case, a three-way joint is required, and the first joint is connected to the filter, and the second is connected. The joint is connected to the oil inlet of the combustion-supporting fuel economy, and the third joint is connected to the oil return outlet of the engine.

In summary, the combustion-supporting fuel-saving device is a key technical equipment suitable for the current energy-saving retrofit of large and medium-sized marine diesel engines and land diesel engines and reducing exhaust emissions. Compared with traditional fuel-saving devices, the advantages mainly reflect the following points. :

1. The combustion-supporting fuel-saving device is easy to install, ensuring that the diesel fuel passing through the fuel-saving device can be fully magnetized and the flow rate is uniform.

Second, the combustion-supporting fuel-saving device is a pure physical treatment technology, which does not cause any harm to the engine, and ensures that the engine oil supply is normal.

Third, the fuel-assisted fuel-saving oil inlet pipe can also be equipped with a three-way joint to fully utilize the engine oil return heat to improve combustion efficiency.

Fourth, the magnetic flux is high, and the magnetized diesel oil has strong fluidity, and acts on the molecular structure to arrange the oil molecules in an orderly manner.
