過渡時期用好“國四”農(nóng)機(jī)的五個關(guān)鍵點

導(dǎo)讀：2022年11月22日，甘肅省農(nóng)業(yè)農(nóng)村廳印發(fā)《關(guān)于農(nóng)機(jī)購置與應(yīng)用補貼農(nóng)業(yè)機(jī)械執(zhí)行國四排放標(biāo)準(zhǔn)的公告》。

　　【農(nóng)機(jī)網(wǎng) 地方農(nóng)機(jī)】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(jī)械用柴油機(jī)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(shù)規(guī)范《非道路柴油移動機(jī)械污染物排放控制技術(shù)要求》(HJ1014-2020)規(guī)定，自2022年12月1日起，所有生產(chǎn)、進(jìn)口和銷售的560kW以下非道路移動機(jī)械及其裝用的柴油機(jī)應(yīng)符合中國第四階段排放標(biāo)準(zhǔn)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(guān)于農(nóng)機(jī)購置與應(yīng)用補貼農(nóng)業(yè)機(jī)械執(zhí)行國四排放標(biāo)準(zhǔn)的公告》，明確“國三”農(nóng)機(jī)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(jī)械產(chǎn)品(以購機(jī)發(fā)票日期為準(zhǔn))應(yīng)符合國家第四階段排放標(biāo)準(zhǔn)，否則不能參與農(nóng)機(jī)購置與應(yīng)用補貼政策。為穩(wěn)妥有序推進(jìn)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(jī)產(chǎn)品(以購機(jī)發(fā)票日期為準(zhǔn))，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(jī)的用戶必須要掌握以下5個技術(shù)要點，才能運用好國四機(jī)：
 
　　一是必須買國四標(biāo)準(zhǔn)的拖拉機(jī)，才能辦理牌照和享受農(nóng)機(jī)購機(jī)補貼政策，市場上原國三拖拉機(jī)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(jī)交易轉(zhuǎn)籍；
 
　　二是必須注意使用上的區(qū)別，國四機(jī)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(jié)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(jī)功率且不要兌水不要錯加柴油，尿素箱蓋是藍(lán)色，柴油箱蓋是黑色；
 
　　三是學(xué)會使用排放后處理系統(tǒng)，嚴(yán)禁長時間怠速運轉(zhuǎn)發(fā)動機(jī)，發(fā)動機(jī)熄火后九十秒內(nèi)，不要斷開拖拉機(jī)主開關(guān)，以便電子泵把尿素液反抽回液箱；
 
　　四是必須按時維護(hù)保養(yǎng)，拖拉機(jī)使用第一個300小時建議進(jìn)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(shè)備需排空尿素箱。
