Experimental Study Of Magnetism Electric Plasma Applied To Automobile Energy Conservation And Consumption Reduction

With the increasing of the amount of the automobile continuously, the contradictions of fuel burning and auto consumption is becoming more and more acute, the total amount of emission for automobile pollution is continuing rising. In recent ten years, in order to alleviate the situation of energy shortage and reduce air pollution, engine researchers have done a lot of useful work, they have studied a variety of new approaches and measures for internal combustion engine to improve the thermal efficiency, and to control harmful emissions. However, there are the conflict between improving energy efficiency and emissions in these methods. The method of this paper presents using magnetic plasma technology for fuel-efficient and emission reduction is based on a new approach. It acts on the air intake of engine, It acts on the air intake of engine, so that the intake air is becoming highly active and polarized-excited state of oxygen-enriched gas, which contains a large number of atomic oxygen (O) and ozone (O3), as well as other strong oxidation free radical (OH *, HO2 *), in the affection of these strong active substances, the burning condition of internal combustion engine is improved, and fuel is fully burning. Consequently, it achieve the target of energy saving and emission reduction.In this article, firstly, the theory of gradient magnetic field and gas discharge produced plasma are discussed, and it analyses the separation mechanism of the paramagnetic oxygen and diamagnetic nitrogen which are subject to different magnetization force under the effection of gradient magnetic field, as well as the the process of discharge plasma make the intake air polarized and excited, producing a large number of active substances(O, O3 and so all), these have laid a theoretical foundation for the technology of magnetism electric Plasma for energy-saving and emission reduction The theory of plasma generated by pulsed high voltage discharge is first discussed in this paper, and the course of chemical reaction which is generated by active ingredient in plasma and main pollutant from automobile exhaust emission is studied. Then, according to the analysis of kinds of existing gradient magnetic nitrogen-oxygen separation equipment and plasma reactors and actual conditions, we have designed an automobile energy-saving and emission-reduction device, which uses the magnetism electric plasma.In order to verify the actual results of the energy-saving and emission-reduction devices, we had done a engine bench test in the Internal Combustion Engine Research Institute of Chongqing University. Experiments show that the devices have good results to reduce vehicle fuel consumption and exhaust emissions, fuel saving rates up to 18.6%, and in emissions HC purification rate of up to 10%, CO 15%, but NOx emissions is increased, it also need to deal with by other exhaust purification measures. At the same time, according to the experimental results, a variety of relevant factors that affect the fuel-saving and purifying effect of the device are also studied. The factors mainly include the different types of magnetization groups, the different types of discharge tube, supply power voltage and the number of energized discharge reaction tube, as this test, we access to the device's the best parameter matching.
