October 30, 2013, reporter learned that, in order to reduce vehicle exhaust pollution sanitation operations, reduce operating costs of vehicle operation, Weifang sanitation department of sanitation pilot vehicle "diesel to gas." The transformation of 11 vehicles for sanitation vehicles and municipal special vehicles has achieved remarkable results.
In recent years, in order to improve cleaning efficiency and quality, road cleaning in Weifang Central City has achieved the main engine suction operation. However, with the continuous rise in fuel prices, the daily cleaning expenses of cleaning companies have gradually increased, and the cost of cleaning has continued to increase. In order to reduce the operating pressure of cleaning companies' operating vehicles and reduce the exhaust pollution of working vehicles, the Weifang Sanitation Department began to carry out the pilot work of “chai gas to gas†with relevant companies in accordance with relevant national energy conservation and emission reduction policies. Among them, the High-tech Zone and Shouguang City have made overall modifications to the main engines and auxiliary engines of road cleaning vehicles, and the secondary engines have been modified in Kuiwen District and Fucheng District.
From the point of view of the pilot projects of “clean-gas-to-gas†by various cleaning companies, the effect is obvious. The cost of running the vehicle is greatly reduced. According to current unit prices for diesel and natural gas, vehicles after “Chai gas reform†can save about half a month compared to vehicles that have not undergone “Chai gas reformâ€. Moreover, the environmental impact of vehicles has been significantly improved and the amount of carbon dioxide emissions has been significantly reduced.
According to reports, the next step, Weifang Sanitation Department will also be combined with the pilot conditions, and further improve and improve the "Chaiqiqi" technology applications in more models, and strive to "Chai gas" this "energy saving, reduce costs" The new technology is gradually extended to different types of sanitation work vehicles.
