中國(guó)一拖：“兩個(gè)市場(chǎng)”一起搶

2022-05-07 13:30:13 來(lái)源：中國(guó)一拖 閱讀量：14655 評(píng)論

　　【農(nóng)機(jī)網(wǎng) 明星企業(yè)】 日前，已生產(chǎn)下線的YTO-NLX904-1出口型窄輪距拖拉機(jī)正在進(jìn)行緊張的試驗(yàn)。
 
　　YTO-NLX904-1出口型窄輪距拖拉機(jī)是中國(guó)一拖技術(shù)中心、大拖公司和國(guó)貿(mào)公司等單位就海關(guān)聯(lián)盟國(guó)家(俄羅斯、哈薩克斯坦、白俄羅斯、亞美尼亞、吉爾吉斯斯坦)CUTR認(rèn)證要求以及700㎜壟作種植區(qū)農(nóng)藝要求，分析論證后立項(xiàng)開(kāi)發(fā)設(shè)計(jì)的出口型窄輪距拖拉機(jī)。
 
　　接到開(kāi)發(fā)任務(wù)后，中國(guó)一拖技術(shù)中心拖拉機(jī)所立即進(jìn)行了設(shè)計(jì)輸入和細(xì)化，并迅速成立YTO-NLX904-1出口型窄輪距拖拉機(jī)專項(xiàng)攻關(guān)項(xiàng)目組，全力投入該機(jī)型的開(kāi)發(fā)工作，并在較短時(shí)間內(nèi)推出試驗(yàn)驗(yàn)證車(chē)。

　　YTO-NLX904-1出口型窄輪距拖拉機(jī)的快速開(kāi)發(fā)，對(duì)開(kāi)拓國(guó)際市場(chǎng)和助力公司高質(zhì)量發(fā)展起到積極作用。當(dāng)前，YTO-NLX904-1出口型窄輪距拖拉機(jī)正在進(jìn)行進(jìn)一步試驗(yàn)和驗(yàn)證。
 
　　同期
 
　　兩臺(tái)歐V大馬力拖拉機(jī)YTO-NLY1054、YTO-NLY1254已順利在青島港裝船發(fā)往歐洲。
 
　　這標(biāo)志著中國(guó)一拖YTO歐V大馬力拖拉機(jī)海外適應(yīng)性測(cè)試正式拉開(kāi)了帷幕。

 
　　YTO歐V大馬力拖拉機(jī)
 

 

　　非道路柴油機(jī)歐Ⅴ排放法規(guī)是目前世界上最嚴(yán)苛的非道路柴油機(jī)尾氣排放法規(guī)。非道路歐Ⅴ排放標(biāo)準(zhǔn)除了對(duì)柴油機(jī)排放技術(shù)和后處理技術(shù)有了更加嚴(yán)格的要求外，對(duì)氮氧化物(NOX)、可吸入懸浮粒子數(shù)量(PN)的排放要求也進(jìn)一步收緊。因此，非道路歐Ⅴ柴油機(jī)的結(jié)構(gòu)和控制邏輯更加復(fù)雜，研發(fā)難度也更大，是對(duì)企業(yè)設(shè)計(jì)研發(fā)水平和生產(chǎn)制造能力的全面考驗(yàn)。
 
　　東方紅LR4A歐Ⅴ柴油機(jī)
 
　　采用高壓共軌+增壓中冷+EGR+DOC+DPF+SCR+ASC的技術(shù)路線，功率覆蓋80~150馬力，技術(shù)和性能均達(dá)到國(guó)際先進(jìn)水平。2021年3月，在德國(guó)萊茵TUV目擊工程師的嚴(yán)格監(jiān)控下，東方紅LR4A柴油機(jī)輕松完成穩(wěn)態(tài)、瞬態(tài)以及非標(biāo)循環(huán)的測(cè)試，EGR、DPF、SCR系統(tǒng)相關(guān)的NCD/PCD故障檢測(cè)及零下18℃的尿素解凍試驗(yàn)等一系列嚴(yán)苛測(cè)試，順利通過(guò)非道路歐Ⅴ排放認(rèn)證試驗(yàn)。
 
　　為保證YTO歐V大馬力拖拉機(jī)海外測(cè)試順利推進(jìn)，國(guó)貿(mào)公司、大拖公司、柴油機(jī)公司、技術(shù)中心等單位通力合作，迅速完成了80~150馬力段4個(gè)型號(hào)的樣機(jī)試制工作。同時(shí)，YTO50~70馬力和150~300馬力非道路歐Ⅴ柴油機(jī)認(rèn)證工作也正在有序推進(jìn)中。
