For vehicles with urea market in the future development of Sichuan Meifeng plus blue green limited liability company, general manager Wujiang Tao believes that as the country Ⅳ emission regulations in-depth implementation, car urea demand in the future may be concentrated mainly in the field of heavy trucks and coaches .

"As far as we know, bus passenger group vehicle urea tender basic price 4000 yuan / ton, assuming an annual consumption of passenger cars 1.5 tons, 1,000 vehicles will need to add the amount of 1,500 tons, the total cost would be 600 million. this for them is not a small expenditure, the state and it has not used specifically for the car urea subsidies, in the absence of special funds to support the case of urea on bus passenger vehicle is a rigid group is increased costs, so they are quite troubled by this thing on the one hand the country Ⅳ car to add urea, on the other hand also increase the cost burden. "Wujiang Tao said.

More must mention is that despite an increase in hard costs, the use of public transport vehicles they are not good. "Bus is currently the main problem is the average vehicle speed is too low." Wujiang Tao said. China's urban transit operating conditions are not ideal large, with an average speed of 30 to 40 km / h, which leads to emissions from vehicle exhaust temperature decomposition of urea to reach the desired temperature. "Decomposition of urea can not, then is ejected to the urea solution, especially after-treatment system is likely to cause clogging." Wujiang Tao explained. He felt that with the increased use of country Ⅳ vehicle, there will be more and more public transport customers encounter this problem.

Therefore, Wujiang Tao believes that the country Ⅳ emission bus ride urea usage is far from ideal, and the country's largest energy saving situation and the needs of urban air pollution, would force buses are increasingly turning to natural gas buses and new energy bus. The overall market from the national point of view, the future of China's leading automotive urea market will eventually focus on the field of heavy trucks and coaches fields.
