Grundfos NoNOx A/S announced it will supply urea dosing systems for Guangxi Yuchai Machinery Company Limited, the largest Chinese manufacturer of heavy-duty engines. Selective catalytic reduction (SCR) systems with Grundfos urea dosing technology will be installed on approximately 450 buses that are to run in Beijing in 2008.
Through the use of SCR systems the buses will meet Euro IV emission standards, while reducing fuel consumption by 4-6%, according to Grundfos. Euro IV emission standards become mandatory in Beijing in 2008, the year of the Olympic Games.
Air pollution in Beijing remains a concern for the organizers of the Olympics. Olympic chief Jacques Rogge has recently said that air pollution could lead to some events at the 2008 Beijing Games being postponed or delayed. In spite of closing a number of factories, air quality in Beijing is deteriorating due to the numerous construction projects and booming car sales.
