  【農(nóng)機(jī)網(wǎng) 熱點(diǎn)關(guān)注】為積極回應(yīng)社會(huì)和廣大用戶的關(guān)切,更好地推進(jìn)農(nóng)機(jī)國(guó)四排放法規(guī)的實(shí)施,中國(guó)農(nóng)機(jī)企業(yè)家峰會(huì)組織編寫了《國(guó)四排放農(nóng)機(jī)產(chǎn)品100問(wèn)》手冊(cè),意在普及國(guó)四排放農(nóng)機(jī)產(chǎn)品的法規(guī)和知識(shí),對(duì)排放升級(jí)中大家關(guān)心的問(wèn)題答疑解惑,便于農(nóng)機(jī)生產(chǎn)企業(yè)、農(nóng)機(jī)經(jīng)銷商、農(nóng)機(jī)使用者以及基層農(nóng)機(jī)管理人員進(jìn)一步了解和認(rèn)識(shí)國(guó)四農(nóng)機(jī)產(chǎn)品,更好地開展相關(guān)工作。
 
  一、法規(guī)篇
 
  1、國(guó)四(非道路柴油移動(dòng)機(jī)械中國(guó)第四階段排放控制)農(nóng)機(jī)產(chǎn)品(簡(jiǎn)稱國(guó)四產(chǎn)品)目前執(zhí)行的排放標(biāo)準(zhǔn)是什么?
 
  答:目前執(zhí)行的排放標(biāo)準(zhǔn)為GB 20891-2014《非道路移動(dòng)機(jī)械用柴油機(jī)排氣污染物排放限值及測(cè)量方法(中國(guó)第三、四階段)》及其修改單、HJ 1014-2020《非道路柴油移動(dòng)機(jī)械污染物排放控制技術(shù)要求》以及GB 36886-2018《非道路移動(dòng)柴油機(jī)械排氣煙度限值及測(cè)量方法》。
 
  2、“國(guó)四”排放標(biāo)準(zhǔn)覆蓋哪些產(chǎn)品?
 
  答:覆蓋產(chǎn)品:在中國(guó)境內(nèi)生產(chǎn)、進(jìn)口、銷售的非道路移動(dòng)機(jī)械及其裝用的柴油機(jī);在道路上用于載人(貨)的車輛裝用的第二臺(tái)柴油機(jī)(比如大型起重機(jī)的上裝柴油機(jī))。
 
  本標(biāo)準(zhǔn)適用于以下(包括但不限于)機(jī)械:工程機(jī)械、農(nóng)業(yè)機(jī)械(包括拖拉機(jī)、聯(lián)合收割機(jī)等)、林業(yè)機(jī)械、機(jī)場(chǎng)地勤設(shè)備、材料裝卸機(jī)械、雪犁裝備、工業(yè)鉆探設(shè)備、空氣壓縮機(jī)、發(fā)電機(jī)組、漁業(yè)機(jī)械(增氧機(jī)、池塘挖掘機(jī)等)、水泵、三輪汽車及其裝用的柴油機(jī)、額定凈功率小于37kW的船舶及其裝用的柴油機(jī)。
 
  3、農(nóng)機(jī)產(chǎn)品國(guó)四標(biāo)準(zhǔn)實(shí)施時(shí)間和范圍是什么?
 
  答:GB 20891-2014修改單及《非道路柴油移動(dòng)機(jī)械污染物排放控制技術(shù)要求》(HJ 1014-2020)2020年12月28日由生態(tài)環(huán)境部發(fā)布并實(shí)施,標(biāo)準(zhǔn)明確:自2022年12月1日起,所有生產(chǎn)、進(jìn)口和銷售的560kW以下(含560kW)非道路移動(dòng)機(jī)械及其裝用的柴油機(jī)應(yīng)符合國(guó)標(biāo)第四階段以及HJ 1014-2020標(biāo)準(zhǔn)要求。560kW以上非道路移動(dòng)機(jī)械及其裝用的柴油機(jī)第四階段實(shí)施時(shí)間另行公告。
 
  4、農(nóng)機(jī)產(chǎn)品排放標(biāo)準(zhǔn)為什么要從國(guó)三升級(jí)到國(guó)四?
 
  答:農(nóng)機(jī)產(chǎn)品排放標(biāo)準(zhǔn)從國(guó)三升級(jí)到國(guó)四,主要有以下好處:
 
  (1)改善空氣質(zhì)量,有利于社會(huì)公眾生活和身體健康
 
  我國(guó) PM2.5濃度居高不下,嚴(yán)重影響了社會(huì)公眾生活和身體健康。包括農(nóng)機(jī)在內(nèi)的非道路移動(dòng)機(jī)械污染排放是影響大氣環(huán)境質(zhì)量的重要因素,其NOx和PM排放量占整個(gè)移動(dòng)源排放的30%和55.4%。NOx和PM(氮氧化物和顆粒物)會(huì)嚴(yán)重危害人體健康,影響動(dòng)植物生長(zhǎng)。隨著標(biāo)準(zhǔn)的實(shí)施,國(guó)四農(nóng)機(jī)和工程機(jī)械保有量占比逐步增加,預(yù)計(jì)4年后當(dāng)年減排比例分別為17.6%和25.5%,9年后年當(dāng)年減排比例分別為34.2%和50.4%,空氣質(zhì)量將得到明顯改善。國(guó)四非道路移動(dòng)機(jī)械采用顆粒物捕集器(DPF),減少99%以上的顆粒物排放,可望徹底解決農(nóng)機(jī)冒黑煙問(wèn)題。
 
  (2)提高農(nóng)機(jī)技術(shù)水平,有利于為用戶提供優(yōu)質(zhì)節(jié)能環(huán)保的農(nóng)機(jī)產(chǎn)品
 
  農(nóng)機(jī)國(guó)三升級(jí)國(guó)四,會(huì)使得柴油機(jī)和整機(jī)的技術(shù)水平進(jìn)一步提高,逐步縮小我國(guó)農(nóng)機(jī)用柴油機(jī)排放控制體系與歐美的差距。同時(shí),國(guó)四標(biāo)準(zhǔn)的實(shí)施會(huì)引導(dǎo)行業(yè)調(diào)整產(chǎn)業(yè)結(jié)構(gòu),對(duì)產(chǎn)品進(jìn)行升級(jí)換代,使得產(chǎn)品結(jié)構(gòu)更加合理,推動(dòng)整個(gè)行業(yè)技術(shù)進(jìn)步。產(chǎn)品的升級(jí)換代,會(huì)為農(nóng)業(yè)生產(chǎn)帶來(lái)優(yōu)質(zhì)、節(jié)能環(huán)保的農(nóng)機(jī)產(chǎn)品,助力農(nóng)民增收、促進(jìn)農(nóng)村產(chǎn)業(yè)發(fā)展和鄉(xiāng)村振興。
 
  5、關(guān)于法規(guī)實(shí)施的時(shí)間點(diǎn),對(duì)于進(jìn)口設(shè)備,以報(bào)關(guān)時(shí)間、貨物進(jìn)口證明書抵運(yùn)日期、入境前完成信息公開、開票時(shí)間還是其它時(shí)間為準(zhǔn)?
 
  答:進(jìn)口設(shè)備以報(bào)關(guān)時(shí)間為準(zhǔn),同時(shí)開票須在2022年12月1日前完成。
 
  6、大于560kW的發(fā)動(dòng)機(jī)及農(nóng)業(yè)機(jī)械如何處理?執(zhí)行國(guó)三階段標(biāo)準(zhǔn)?也可申報(bào)國(guó)四階段?
 
  答:560kW以上的柴油機(jī)及機(jī)械可以繼續(xù)生產(chǎn)、銷售和進(jìn)口國(guó)三產(chǎn)品。如果能夠滿足第國(guó)四階段的相關(guān)要求,也可申報(bào)國(guó)四。
 
  7、國(guó)四階段具體的排放限值規(guī)定是怎樣的?
 
  答:國(guó)四排放限值如下表
 
  非道路移動(dòng)機(jī)械用柴油機(jī)排氣污染物排放限值

 
  8、國(guó)四農(nóng)機(jī)法規(guī)實(shí)施的技術(shù)措施有哪些?
 
  答:國(guó)四農(nóng)機(jī)37kW以上產(chǎn)品的排放控制需要安裝后處理來(lái)實(shí)現(xiàn)達(dá)標(biāo)排放。采用的主流技術(shù)路線有:EGR+DOC+DPF技術(shù)路線和DOC+DPF+SCR技術(shù)路線。為有效監(jiān)控后處理系統(tǒng)是否正常工作,引入NOx控制/診斷(NCD)和PM控制/診斷(PCD)以及診斷通訊和精準(zhǔn)定位。為保證產(chǎn)品持續(xù)達(dá)標(biāo),根據(jù)功率段的不同需要采用PEMS和煙度測(cè)試的方法進(jìn)行新生產(chǎn)和在用機(jī)械的達(dá)標(biāo)檢查。為加強(qiáng)對(duì)農(nóng)業(yè)機(jī)械管理,要求37kW以上農(nóng)機(jī)加裝精準(zhǔn)定位系統(tǒng)。
 
  9、國(guó)四農(nóng)機(jī)產(chǎn)品是否需要安裝精準(zhǔn)定位系統(tǒng)?精準(zhǔn)定位系統(tǒng)壽命要求
 
  答:裝用額定凈功率 37 kW及以上柴油機(jī)的機(jī)械 ,出廠前應(yīng)加裝精準(zhǔn)定位系統(tǒng)。機(jī)械生產(chǎn)企業(yè)應(yīng)確保精準(zhǔn)定位系統(tǒng)在機(jī)械全壽命期內(nèi)應(yīng)正常工作。
 
  10、精準(zhǔn)定位系統(tǒng)的技術(shù)要求?
 
  答:精度要求應(yīng)滿足:
 
  (1)水平定位精度為小于10 m;
 
  (2)定位時(shí)間:
 
 ?、倮鋯?dòng):從系統(tǒng)加電運(yùn)行到實(shí)現(xiàn)捕獲時(shí)間不應(yīng)超過(guò)120s;
 
 ?、跓釂?dòng):實(shí)現(xiàn)捕獲時(shí)間應(yīng)小于10s。
 
  (3)柴油機(jī)啟動(dòng)后60s內(nèi)必須開始傳輸位置,傳輸頻率是10min一次;
 
  (4)柴油機(jī)停機(jī)后不需要傳輸定位信息。
 
  11、排放控制診斷系統(tǒng)和排放控制系統(tǒng)可以擅自更改嗎?
 
  答:無(wú)論企業(yè)或個(gè)人均不能擅自更改。機(jī)械生產(chǎn)企業(yè)有責(zé)任防止國(guó)四產(chǎn)品的排放控制診斷系統(tǒng)和排放控制單元被篡改,國(guó)四產(chǎn)品上應(yīng)具有防止篡改的功能。如果被篡改,機(jī)械生產(chǎn)企業(yè)應(yīng)查明原因向生態(tài)環(huán)境主管部門說(shuō)明,給出防篡改可行技術(shù)解決方案,并在新生產(chǎn)的國(guó)四產(chǎn)品上采取相應(yīng)補(bǔ)救措。
 
  12、機(jī)械生產(chǎn)企業(yè)應(yīng)保證排放相關(guān)零部件在機(jī)械有效壽命期內(nèi)的正常功能,有效壽命如何界定?
 
  答:機(jī)械有效壽命是與機(jī)械裝用的柴油機(jī)有效壽命完全一致的時(shí)間周期,而柴油機(jī)的有效壽命是指保證非道路移動(dòng)機(jī)械用柴油機(jī)及其排放控制系統(tǒng)的正常運(yùn)轉(zhuǎn)并符合有關(guān)氣態(tài)污染物和顆粒物排放限值,且已在型式核準(zhǔn)時(shí)給予確認(rèn)的使用時(shí)間。應(yīng)保證柴油機(jī)的排放控制裝置在下表規(guī)定的有效壽命期內(nèi)正常運(yùn)轉(zhuǎn),且污染物排放符合標(biāo)準(zhǔn)規(guī)定的限值要求。
 
  耐久性時(shí)間要求
 

 

  13、標(biāo)準(zhǔn)中提出了“排放質(zhì)保期”、“機(jī)械有效壽命”和“機(jī)械全壽命周期”等概念,在相應(yīng)時(shí)間周期內(nèi)出現(xiàn)排放超標(biāo)后的相關(guān)責(zé)任如何區(qū)分?
 
  答:“排放質(zhì)保期”指的是該時(shí)間內(nèi),排放相關(guān)零部件非用戶責(zé)任損壞或者劣化,導(dǎo)致排放超標(biāo),生產(chǎn)企業(yè)要免費(fèi)進(jìn)行更換。生產(chǎn)企業(yè)應(yīng)對(duì)排放相關(guān)零部件的排放質(zhì)保期做出自我承諾,且不應(yīng)短于HJ 1014-2020標(biāo)準(zhǔn)中的“環(huán)保關(guān)鍵零部件排放質(zhì)保期要求”。信息公開時(shí),應(yīng)公開排放相關(guān)零部件名單及其相應(yīng)的質(zhì)保期,并將以上信息在產(chǎn)品說(shuō)明書中進(jìn)行說(shuō)明。
 
  環(huán)保關(guān)鍵零部件排放質(zhì)保期要求
 

 

  “機(jī)械有效壽命”指的是該時(shí)間內(nèi),排放必須要達(dá)標(biāo),如果不達(dá)標(biāo),整機(jī)生產(chǎn)企業(yè)應(yīng)進(jìn)行維修、維護(hù)使得排放達(dá)標(biāo)。
 
  “機(jī)械全壽命周期”指的機(jī)械從生產(chǎn)出來(lái)到報(bào)廢的全生命周期。標(biāo)準(zhǔn)要求全壽命期排放控制策略要起作用,同時(shí)要求精準(zhǔn)定位系統(tǒng)和遠(yuǎn)程監(jiān)控終端都要在全壽命周期起作用,整機(jī)企業(yè)對(duì)此負(fù)責(zé)。
 
  14、農(nóng)機(jī)企業(yè)在國(guó)四產(chǎn)品開發(fā)、生產(chǎn)和銷售過(guò)程中要做哪些確認(rèn)?
 
  答:(1)新機(jī)開發(fā)生產(chǎn)時(shí)進(jìn)行環(huán)保信息公開,定位信息聯(lián)調(diào)確認(rèn);(2)新機(jī)出廠按照規(guī)定進(jìn)行煙度確認(rèn);(3)在出廠后500小時(shí)內(nèi)對(duì)新生產(chǎn)的機(jī)械按系族進(jìn)行排放達(dá)標(biāo)自查,并將 自查計(jì)劃和自查結(jié)果進(jìn)行信息公開;(4)生產(chǎn)企業(yè)應(yīng)制定在用符合性自查計(jì)劃,對(duì)上市18個(gè)月內(nèi)的產(chǎn)品開展在用符合性自查并將自查報(bào)告進(jìn)行信息公開。
 
  15、國(guó)四產(chǎn)品怎么進(jìn)入國(guó)家補(bǔ)貼目錄?
 
  答:國(guó)四農(nóng)機(jī)要進(jìn)入國(guó)家補(bǔ)貼目錄首先需要企業(yè)做好三點(diǎn):一是企業(yè)在信息公開后獲得唯一的機(jī)械環(huán)保代碼;二是符合條件的國(guó)三產(chǎn)品通過(guò)信息變更,經(jīng)原鑒定機(jī)構(gòu)確認(rèn);三是新產(chǎn)品取得國(guó)四農(nóng)機(jī)推廣鑒定證書。
 
  2022年6月4日,農(nóng)業(yè)部農(nóng)業(yè)機(jī)械化總站發(fā)布了《關(guān)于做好柴油機(jī)排放標(biāo)準(zhǔn)升級(jí)農(nóng)業(yè)機(jī)械試驗(yàn)鑒定獲證產(chǎn)品信息變更等相關(guān)工作的通知》,其中明確表示獲證產(chǎn)品鑒定信息的確認(rèn)、變更采取“企業(yè)自主變更”的方式。
 
  目前,企業(yè)可自主進(jìn)行變更的為所有升級(jí)國(guó)四排放標(biāo)準(zhǔn)的農(nóng)機(jī)鑒定獲證產(chǎn)品。其中滿足相關(guān)結(jié)構(gòu)和特征參數(shù)變化要求的農(nóng)用柴油機(jī)、輪式和履帶拖拉機(jī)、手扶拖拉機(jī)這3種產(chǎn)品亦可自主變更,其他產(chǎn)品參數(shù)變化應(yīng)符合鑒定大綱的變更要求。如果不滿足變更要求的產(chǎn)品,只能通過(guò)重新申請(qǐng)鑒定獲取證書。
 
  16、“國(guó)四”排放標(biāo)準(zhǔn)實(shí)施后,主機(jī)制造商是否還能生產(chǎn)和銷售“國(guó)三”新機(jī)?如何進(jìn)行豁免備案?
 
  答:2022年12月1日以后,中國(guó)境內(nèi)既不允許生產(chǎn),也不允許銷售“國(guó)三”新機(jī);發(fā)動(dòng)機(jī)制造商生產(chǎn)560kW以下(含560kW)“國(guó)三”發(fā)動(dòng)機(jī),需要進(jìn)行備案后方可生產(chǎn);如果用于出口,需要向生態(tài)環(huán)境部機(jī)動(dòng)車排污監(jiān)控中心(以下簡(jiǎn)稱:VECC)備案豁免;主機(jī)制造商生產(chǎn)“國(guó)三”主機(jī),需要進(jìn)行備案后方可生產(chǎn),如果用于出口,需要向VECC備案豁免;同樣,主機(jī)制造商進(jìn)口560kW以下(含560kW)“國(guó)三”發(fā)動(dòng)機(jī),也需要向VECC備案豁免。
 
  目前標(biāo)準(zhǔn)豁免條件包括出口、展覽、應(yīng)急、救援、匹配試驗(yàn)和替換在用發(fā)動(dòng)機(jī)。企業(yè)可通過(guò)信息公開系統(tǒng)“豁免欄”備案,具體備案流程和操作指南可參見豁免欄中提的供模板。
 
  17、對(duì)于排放異常情況如何界定是由用戶加注不合規(guī)燃油和車用尿素(反應(yīng)劑)導(dǎo)致的,誰(shuí)來(lái)界定?
 
  答:誰(shuí)主張誰(shuí)舉證。
 
  18、油液監(jiān)管中,由于潤(rùn)滑油(機(jī)油)的質(zhì)量也會(huì)對(duì)排放質(zhì)保期產(chǎn)生影響,對(duì)于機(jī)油的監(jiān)管有沒(méi)有相關(guān)考慮?
 
  答:暫未涉及機(jī)油的要求,生產(chǎn)企業(yè)應(yīng)在產(chǎn)品說(shuō)明書里明確規(guī)定柴油機(jī)對(duì)機(jī)油的要求。如果因?yàn)榭蛻羰褂貌缓弦?guī)的機(jī)油造成排放超標(biāo),企業(yè)提供證明后,排放超標(biāo)與企業(yè)無(wú)關(guān)。
 
  19、2022年12月1日后,企業(yè)不得再銷售國(guó)三農(nóng)機(jī),屆時(shí)國(guó)三的庫(kù)存怎么辦?
 
  答:企業(yè)可以將國(guó)三農(nóng)機(jī)出口至排放要求與我國(guó)國(guó)三相同或低于國(guó)三排放要求的國(guó)家。
