導讀:2022年11月22日,甘肅省農(nóng)業(yè)農(nóng)村廳印發(fā)《關于農(nóng)機購置與應用補貼農(nóng)業(yè)機械執(zhí)行國四排放標準的公告》。

  【農(nóng)機網(wǎng) 地方農(nóng)機】根據(jù)生態(tài)環(huán)境部和國家市場監(jiān)督管理總局于2020年12月聯(lián)合發(fā)布的《非道路移動機械用柴油機排氣污染物排放限值及測量方法(中國第三、四階段)》(GB 20891-2014)修改單,及其配套技術規(guī)范《非道路柴油移動機械污染物排放控制技術要求》(HJ1014-2020)規(guī)定,自2022年12月1日起,所有生產(chǎn)、進口和銷售的560kW以下非道路移動機械及其裝用的柴油機應符合中國第四階段排放標準要求(簡稱“國四”)。
 
  2022年11月22日,甘肅省農(nóng)業(yè)農(nóng)村廳印發(fā)《關于農(nóng)機購置與應用補貼農(nóng)業(yè)機械執(zhí)行國四排放標準的公告》,明確“國三”農(nóng)機產(chǎn)品補貼資質(zhì)截止到2022年11月30日(含),自2022年12月1日(含)起,凡購置的柴油動力農(nóng)業(yè)機械產(chǎn)品(以購機發(fā)票日期為準)應符合國家第四階段排放標準,否則不能參與農(nóng)機購置與應用補貼政策。為穩(wěn)妥有序推進補貼申請辦理,對2022年11月30日(含)前購置的符合政策規(guī)定的“國三”農(nóng)機產(chǎn)品(以購機發(fā)票日期為準),補貼申請辦理時限延長至2023年5月31日。因此,2023年打算購買農(nóng)機的用戶必須要掌握以下5個技術要點,才能運用好國四機:
 
  一是必須買國四標準的拖拉機,才能辦理牌照和享受農(nóng)機購機補貼政策,市場上原國三拖拉機已停止銷售,無論從什么渠道購買都無法落籍,只能作為二手拖拉機交易轉籍;
 
  二是必須注意使用上的區(qū)別,國四機最大的變化就是增加了32.5%的尿素溶液,要保證尿素液配比和品質(zhì),因為劣質(zhì)尿素在使用過程中容易形成結晶,堵塞廢氣處理系統(tǒng)造成故障,尿素液位低于5%會限制發(fā)動機功率且不要兌水不要錯加柴油,尿素箱蓋是藍色,柴油箱蓋是黑色;
 
  三是學會使用排放后處理系統(tǒng),嚴禁長時間怠速運轉發(fā)動機,發(fā)動機熄火后九十秒內(nèi),不要斷開拖拉機主開關,以便電子泵把尿素液反抽回液箱;
 
  四是必須按時維護保養(yǎng),拖拉機使用第一個300小時建議進行一次手動強制再生,讓后處理系統(tǒng)高溫工作,分解灰質(zhì),去除有害雜質(zhì);
 
  五是使用正規(guī)廠家的柴油,若長時間存放設備需排空尿素箱。
