【正文】 ess even regeneration technology are still evolving. Price and low sulfur diesel will restrict its widely used in China, but currently it can be well used in city bus and trucks, no matter OEM or inuse retrofit ,to sharply reduce central cities’ PM emission. 4 中國后處理裝置市場展望 OUTLOOK on Chinese Diesel Aftertreatment Market ? NOx后處理產(chǎn)品， SCR是目前中國中重型柴油車的主流方案，但初步研究發(fā)現(xiàn)裝在城市運行車輛上實際效果不佳。輕型柴油車主要通過 EGR降低 NOx排放。 LNC有待研究。 As for DeNOx products, SCR is main solution for Chinese medium and heavyduty diesel vehicle, but primary research found its real time emission data wasn’t expected. Lightduty diesel NOx is reduced by EGR. ? 目前上述后處理裝置在中國都有生產(chǎn)，市場上主要是 CVEC成員單位產(chǎn)品。但柴油制約國四標(biāo)準(zhǔn)還未全面實施，柴油后處理產(chǎn)品數(shù)量不大。 Main diesel aftertreatments can be found in Chinese market, produced by CVEC members, but quantity is limited because of delay of China IV. ? 綜合來看，柴油車后處理裝置的中國市場主要在污染較嚴(yán)重的大城市或城市群。技術(shù)上 輕型柴油車采用 EGR+DPF方案；城市車輛主要采用 DPF或者DPF+SCR終極方案；城市間運行的重型車采用 SCR產(chǎn)品。 Chinese diesel aftertreatment market will be in big cities. 4 中國后處理裝置市場展望 OUTLOOK on Chinese Diesel Aftertreatment Market ? 鑒于進一步降低柴油車排放需要柴油質(zhì)量的改善和柴油中有害物特別是硫含量的大幅降低，我們呼吁政府相關(guān)部門協(xié)作同步推進柴油清潔化。 Diesel quality especially sulfur content is key to diesel vehicle emission reduction equipments, Government shall do more work to promote clean diesel national wide. ? 鑒于加裝后處理裝置會明顯提高車輛成本，我們呼吁相關(guān)企業(yè)自律的同時更強烈希望政府相關(guān)部門加強產(chǎn)品一致性監(jiān)管，創(chuàng)造公平競爭環(huán)境和正常的柴油后處理裝置使用環(huán)境。 Diesel emission reduction equipments will increase vehicle price, Government departments shall strengthen COP check to ensure they are right equipped and used. That’ll be fair to all petitory vehicle and aftertreatment device manufactures.
