Robert Bosch GmbH broke ground last week on its second diesel fuel injector plant in China. The 1.6 billion yuan ($257 million) facility in Qingdao in east China's Shandong province will start production in 2018.

It will mainly make diesel fuel injectors for light- and heavy-duty trucks as well as cars, the German parts supplier said in a statement. Bosch's first common rail injector plant is in Wuxi in east China's Jiangsu province.

Like the first plant, the Qingdao plant will be jointly owned by Bosch and Wuxi Weifu, a Chinese diesel injector manufacturer.

In July, China will adopt the National IV emission standards, which are similar to the Euro IV emission standards. Bosch expects tougher emission controls to boost market demand in China for its diesel technology.
