【摘要】：以壓縮空氣為氣源,建立了低溫等離子體(NTP)噴射系統(tǒng)再生廢氣再循環(huán)(EGR)冷卻器的試驗系統(tǒng),在不同的再生溫度下進行EGR冷卻器的再生試驗,通過測量再生過程中主要活性物質(zhì)(NO2、O3)以及再生產(chǎn)物COx的變化情況,分析了再生溫度對EGR冷卻器再生的影響。試驗結(jié)果表明:空氣源NTP能在18~300℃的溫度范圍內(nèi)實現(xiàn)EGR冷卻器再生。再生過程中,O3和NO2均隨著溫度的升高而降低,在150℃時被完全消耗。再生過程產(chǎn)生的CO較少,故C1(CO中C的質(zhì)量)的值較小,占C12(COx中C的質(zhì)量)的比例不足1/8。而C2(CO2中C的質(zhì)量)與C12的趨勢趨于一致,均隨著溫度的升高先增加后減小,當再生溫度為150℃時,C2和C12均達到較大值。當再生溫度為150℃時,NTP產(chǎn)生的活性物質(zhì)的利用率較高,去除積碳量較多,再生效果較好。
[Abstract]:Using compressed air as the gas source, a low temperature plasma jet (NTP) regeneration system of exhaust gas recirculation (EGR) test system test EGR regeneration cooler, cooler in the regeneration of different temperatures, the main active substances measured during regeneration (NO2, O3) and the changes of recycled products of COx, analyzes the influence of regeneration the temperature on the regeneration of the EGR cooler. The experimental results show that air source NTP EGR cooler can achieve regeneration in the temperature range of 18~300 DEG C. The regeneration process, O3 and NO2 were decreased with the increase of the temperature, was completely consumed in 150 degrees. The regeneration process produces less CO, so the C1 (quality of CO C the) small value, accounting for C12 (quality COx C) and 1/8. C2 (the ratio of less than CO2 in quality C) consistent with the trend of C12, with the increase of temperature increased first and then decreased, when the regeneration temperature is 150 DEG C, C2 and C12 have reached a When the regeneration temperature is 150 C, the utilization ratio of the active substance produced by NTP is high, the carbon content is more and the regeneration effect is better.

【正文快照】： 引言目前,柴油機以其燃油經(jīng)濟性好、CO2排放低等優(yōu)點,廣泛應(yīng)用于重型車領(lǐng)域,同時也日益受到輕型車和乘用車市場的青睞。但柴油機空氣-燃料的混合方式,導(dǎo)致其PM和NOx的排放高于汽油機。目前各國的排放法規(guī)日益嚴格,這就要求汽車生產(chǎn)廠家減少柴油車PM和NOx的排放。為滿足排放法，
