对于随车吊汽车企业，推到IV模型是没有问题的。中国重汽随车吊的人士向记者表示，“国Ⅳ东风随车吊排放标准的实施，企业产品的技术没有问题，油不能同步升级是推广的最大的问题。”
National passenger car market information exchange association deputy secretary-general Yang Zaishun said, in the existing emission reduction technology, diesel urea SCR (emissions after treatment) system smaller changes on the car, high tolerance on product quality, and also improved in terms of fuel consumption, is now "the optimum use of technology".
全国乘用车市场信息交流协会副秘书长杨再舜说，在现有的减排技术，柴油机尿素SCR（排放后处理）系统的小的变化的随车起重运输车汽车，对产品质量的高耐受性，和改进的燃料消耗方面，现在是“最佳使用技术”。
A long term to Dongfeng commercial vehicle delivery vehicle for urea production enterprises personage Liu Peng (a pseudonym) is introduced, 10 liters of urea using kilometers average is 5000 kilometres, average price per liter to 5 yuan.
一个长期的东风商用车后双桥随车吊的配送车辆的尿素生产企业人士刘鹏（化名）介绍，10升使用公里平均尿素为5000公里，每公升汽油的平均价格为5元。
"Although the use of the initial costs rise, but China IV engine synchronization by using the high pressure common rail and SCR technology can make the fuel consumption is reduced by at least 5% in the national III basis, in fact this initial cost in 1~2 years can save fuel consumption by full recovery." Liu Peng sa
“尽管初始成本上升的使用，但中国四引擎同步采用高压共轨和SCR技术可使燃料消耗是由国家III基础上至少减少5%，事实上在1 ~这2年的初始成本可完全恢复随车吊价格，节省燃料消耗。”刘鹏说。
Relevant data shows, with urea in the consumption of 11000 tons in 2011 our country car, only accounted for global vehicle urea solution consumption 1%. Accordingly before the industry is expected, if the strict implementation of emissions, urea for five years the cars annual demand of up to 7000000 tons
相关数据显示，在2011我国汽车消费量11000吨尿素，仅占全球车用尿素溶液消耗量的1%。因此在业内人士预计，如果排放的严格执行，五年尿素7000000吨的汽车的年需求量。
