【正文】 30%,降低尾氣排放約50%90%,同時(shí)還能使動(dòng)力增加10%30%。日前,一種可將普通燃油變成納米燃油的裝置已經(jīng)在北京上市。據(jù)這種名為“EPS納米燃油裝置”的發(fā)明人王文浩介紹,普通燃油內(nèi)含有大量尺寸大于300納米的分子團(tuán)簇,但經(jīng)過(guò)EPS納米燃油裝置處理后,燃油分子成分顆粒的尺度均小于3納米,就變成了“納米燃油”,其更加有利于充分燃燒,所以能夠降低油耗和尾氣排放,提高動(dòng)力。在汽車上加裝納米燃油裝置很簡(jiǎn)單,也比較經(jīng)濟(jì),普通轎車只需要580元。目前,在北京地區(qū)已經(jīng)對(duì)幾百輛車進(jìn)行了試裝,效果良好。據(jù)統(tǒng)計(jì),如果使用EPS納米燃油裝置處理過(guò)的燃油,以節(jié)約15%計(jì)算,合2550噸,相當(dāng)于中國(guó)全年進(jìn)口石油總量的四分之一,價(jià)值51億美元。四、超星電子圖書(shū)檢索式E. 書(shū)名=汽車*主題詞=污染檢索步驟與結(jié)果用檢索式E進(jìn)行檢索,命中2條結(jié)果,取兩條結(jié)果如下:1 【書(shū)名】汽車排放污染及控制【作者】龔金科主編【出版】人民交通出版社2005年4月 【摘要】本書(shū)系統(tǒng)地闡述了汽車排放污染物的危害、生成機(jī)理和影響因素以及車用汽油機(jī)和柴油機(jī)的機(jī)內(nèi)凈化技術(shù)。全書(shū)分為緒論、汽車排放污染物的生成和影響因素、汽車發(fā)動(dòng)機(jī)的排放特性、車用汽油機(jī)機(jī)內(nèi)凈化、車用柴油機(jī)機(jī)內(nèi)凈化、車用汽油機(jī)后處理凈化、車用柴油機(jī)后處理凈化、燃料與排放、汽車排放污染物凈化方案及分析、汽車排放測(cè)試、排放標(biāo)準(zhǔn)11章。并附有參考文獻(xiàn)。 2 【書(shū)名】汽車排放與環(huán)境保護(hù)【作者】葛蘊(yùn)珊主編【出版】中國(guó)勞動(dòng)社會(huì)保障出版社2006年9月第1版 【摘要】本書(shū)是高等職業(yè)技術(shù)院校汽車檢測(cè)與維修專業(yè)的教學(xué)用書(shū)。本書(shū)詳細(xì)介紹了汽車、發(fā)動(dòng)機(jī)的主要有害排放物對(duì)大氣環(huán)境的影響和污染控制技術(shù)。主要內(nèi)容包括汽油機(jī)有害排放物的生成機(jī)理和控制措施,柴油機(jī)有害排放物的生成機(jī)理和控制措施,三效催化反應(yīng)器的工作原理和應(yīng)用技術(shù),柴油機(jī)微粒捕集器的技術(shù)現(xiàn)狀,在用車的排放控制措施和排放診斷技術(shù),排放法規(guī)和測(cè)量技術(shù),車用燃料的發(fā)展和代用燃料技術(shù)等。 國(guó)家知識(shí)產(chǎn)權(quán)局專利數(shù)據(jù)庫(kù)檢索式F.(名稱=汽車and尾氣)and(摘要=(控制or凈化)and(技術(shù)or裝置)) 檢索步驟與結(jié)果用檢索式F進(jìn)行檢索,命中發(fā)明專利28條,實(shí)用新型專利104條,經(jīng)過(guò)篩選,選擇其中4條:1 【發(fā)明名稱】陶瓷載體負(fù)載催化劑的汽車尾氣凈化裝置及其制備方法【發(fā)明人】王慧;曾令可;段碧林等【專利號(hào)】 【摘要】本發(fā)明提供了陶瓷載體負(fù)載催化劑的汽車尾氣凈化裝置及其制備方法。尾氣凈化裝置由陶瓷載體以及負(fù)載在載體上的催化劑構(gòu)成,陶瓷載體為莫來(lái)石纖維多孔陶瓷;催化劑活性組份為三元稀土鈣鈦礦鹽復(fù)合氧化劑。制備時(shí),先以磷酸、氫氧化鋁和莫來(lái)石纖維制備載體,再按催化劑化學(xué)式化學(xué)計(jì)量比,配置La、Sr、Co的硝酸鹽水溶液,然后將載體浸漬在催化劑溶液中,最后進(jìn)行焙燒。制備的陶瓷載體孔隙率高、耐高溫、熱膨脹系數(shù)較小、抗熱震性良好,孔洞的大小、密度、形狀等容易控制;且載體孔洞為三維立體的開(kāi)孔結(jié)構(gòu);該催化劑對(duì)CO和NO都有很高轉(zhuǎn)化率。2 【發(fā)明名稱】一種汽車尾氣凈化催化劑的制備方法【發(fā)明人】王來(lái)軍;文明芬;李玉山等 【專利號(hào)】 【摘要】一種汽車尾氣凈化催化劑的制備方法,屬于汽車尾氣凈化催化劑的制備技術(shù)領(lǐng)域。本發(fā)明首先制備含有鈰和鋯并添加鑭、鐠、釔、鐵、錳、銅或鋇的一種或幾種金屬元素的復(fù)合氧化鋁涂層,將復(fù)合氧化鋁涂層涂覆在堇青石蜂窩陶瓷載體上,采用化學(xué)鍍的方法實(shí)現(xiàn)貴金屬鈀的負(fù)載。該方法工藝簡(jiǎn)單,所制備的催化劑具有活性高和成本低的優(yōu)點(diǎn)。3 【發(fā)明名稱】一種新型汽車尾氣處理裝置【發(fā)明人】馮永成;馬洪娟【專利號(hào)】 【摘要】本實(shí)用新型公開(kāi)了一種用于汽車尾氣處理的裝置,其特征在于利用該裝置的凈化系統(tǒng)和冷卻系統(tǒng)可將汽車尾氣中的氣體和固體顆粒污染物同時(shí)收集和去除。其主要構(gòu)造原理包括一個(gè)帶有防倒吸自動(dòng)止回閥的尾氣進(jìn)氣彎管,此管的最底端沒(méi)入凈化罐的水溶液中,凈化罐與高位水箱相連,高位水箱中盛有含表面活性劑的堿性水溶液,凈化罐中的水溶液通過(guò)浮球閥自動(dòng)調(diào)節(jié)水位高度,凈化上部為冷卻水夾套,冷卻水夾套與冷卻水水箱相連,凈化罐的上頸部有兩層不銹鋼篩網(wǎng),凈化罐與消音器通過(guò)連接管相連,凈化罐的底部還設(shè)有一個(gè)排水閥,以便對(duì)凈化罐的清洗和維修時(shí)使用。 4 【發(fā)明名稱】汽車尾氣過(guò)濾器【發(fā)明人】楊林 【專利號(hào)】 【摘要】普通汽車的尾氣排放裝置不能變尾氣為無(wú)害氣體,導(dǎo)致大氣污染,危害人身健康。本發(fā)明主要由內(nèi)燃機(jī)、燃料箱、發(fā)動(dòng)機(jī)、尾氣處理裝置、尾氣管、化學(xué)催化劑、電池、開(kāi)關(guān)、導(dǎo)線構(gòu)成。其特征是:過(guò)濾箱的整體位置放置連接在尾氣處理裝置的內(nèi)腔位置,過(guò)濾箱的兩端位置分別連接在尾氣管(進(jìn))和尾氣管(出)的接頭位置,化學(xué)催化劑的整體位置連接在電熱板的上表面位置,制作簡(jiǎn)單,成本低廉,使用方便,易于推廣。六、Springer LinkSearch Word: automobile exhaust emission1【TITLE】Automobile Exhaust Emission Testing【BY】Horst Klingenberg【FROM】SpringerVerlag Berlin Heidelberg 1996;Exhaust Emission Measuring TechniquesQuo Vadis;Pages 363365【ABSTRACT】Differing legislation between countries or unions of countries involved in pollution reduction has turned gas measuring technology into such an extremely extensive and plex field that only a few specialists in environmental agencies and the automobile industry have a grasp of it. This book is intended as an overview of the basics of exhaust gas measuring technology describing the interrelation between emissions, immissions and the effects of pollutants. It aims to provide experts and students alike with an understanding of the interrelationships and details within this field. The results presented are based on the experience gathered by the author during work spanning more than two decades in the automobile industry.2【TITLE】Solidstate sensors for inline monitoring of NO2 in automobile exhaust emission【BY】G. M. KaleEmail authorL. WangJ. E. HayesJ. CongjinY. R. Hong【FROM】Journal of Materials Science November 2003, Volume 38, Issue 21, pp 4293–4300: 245~257【ABSTRACT】Three types of planar solidstate sensors for measuring NO2 in a gas mixture has been designed and tested in the laboratory under controlled atmosphere between 573–723 K. The concentration of NO2 in the gas mixture was in the range of 0–500 ppm with the balance gas consisting of air. The three types of NO2 gas sensors that have been tested in this investigation can be schematically represented as follows:Pt, NO2 + air, NaNO3 + Ba(NO3)2 | NASICON disk | Porous YSZ disk | NO2 + air, Pt (I)Pt, NO2 + air, NaNO3 + Ba(NO3)2 | NASICON disk | YSZ thin film | NO2 + air, Pt (II)Pt, NO2 + air, Pt | YSZ disk | Au ? Pd, NO2 + air, Pt (III)In sensor (I) the two solid electrolyte disks were attached by diffusion bonding at elevated temperature whereas in sensor (II) the (8 mol% Y2O3–ZrO2) YSZ thin film was deposited on (Na3Zr2Si2PO12) NASICON disk by radio frequency (RF) magnetron sputtering technique. The measured open circuit electromotive force (Emf) of each sensor was found to attain stable value at all the concentrations of NO2 in the gas mixture and also varied linearly as a function of the logarithm of the partial pressure of NO2 in the gas mixture. The time required to reach 90% of the stable emf at a fixed concentration of NO2 and at a constant temperature was found to be 30–40 min for sensor (I) and approximately 2–3 min for sensor (II) and (III).3【TITLE】The Legislative Process of Automobile Exhaust Emissions Control in Japan—The 1966 Regulation and the Role of the Ministry of Transport【BY】Akira Itagaki【FROM】MicroPerformance During Postwar Japan’s HighGrowth Era (2016):127~132【ABSTRACT】This paper examines the process and significance of the enactment of exhaust emission control in Japan. In the 1960s, the health hazards caused by exhaust emissions became a serious social problem. The Ministry of Transport’s existing regulations had been based on insufficient research, and emissions were not regulated by numeric values. The Ministry therefore undertook another study and surveyed the effect of exhaust emissions on air pollution. It also took into account the views of automobile panies in drafting new regulations.The resulting regulations proved only transitional, however. Because the study of exhaust emissions was not thorough enough, controls were imposed only on CO, in effect reflecting the technical capabilities of the automobile panies and having only a limited effect on air pollution. But it did have some significance as it served as the foundation for subsequent exh
