BEIJING – Delphi plans to build its first global production line of a new generation GDi high pressure fuel pump capable of up to 400 bar continuous operating pressure in China, according to a report in China Automotive News.
This technology is devoted to help OEMs meet challenges posed by the coming State-VI emissions regulations in China.
This new technology features reduced actuation noise generation due to internal design changes and the optimization of the spill valve drive current. Besides, by means of this new generation GDi fuel pump, the complete combustion can be achieved to the largest extent with better emissions reduction. Furthermore, this 400 bar fuel pump can play its full potential out without additional diesel particulate filters and additional cost can be reduced accordingly.
Kevin Quinlan, global vice president of Delphi gasoline engine management system, said: “The goal of the Chinese government is very clear, which is to reduce CO2 emissions and improve fuel economy. Therefore, many harsh policies and regulations are in place, which is depressing for OEMs. To help with this emission reduction goal, we believe that it is the right time for us to bring this technology into China to help OEMs to meet stricter emission standards.”
Quinlan added: “Chinese automotive market is developing fast. Last year we introduced our 200 bar fuel pump into China and now we decide to introduce our 400 bar fuel pump into China to help OEMs meet the coming State-VI emission standards. In addition, we also intend to bring our valve train technology, continuous variable cam phaser, new generation VVT technology and 2-step valve lift system into China.”
Xu Xiangdong, engineering director of powertrain system at Delphi Asia Pacific, said: “The biggest advantage of Delphi 400 bar fuel pump is that it can help OEMs meet Euro 6C standard. And it is extremely hard to master the technology to reduce the emitted particulate amount to the required level of Euro 6C.”
