Delphi Technologies announced that the company will introduce a new 500+ bar GDi system that can reduce particulate emissions and fuel consumption at the 2019 Vienna Motor Symposium. The company claims that the new system can cut down particulate emissions by up to 50% as compared to state-of-the-art 350 bar system without expensive engine design modifications. Reducing the number of exhaust gas particulates, including those smaller than 23 nm, it will help manufacturers meet increasingly stringent future global emissions standards.

Mr Walter Piock, chief engineer, Gasoline Systems, Delphi Technologies said that “The industry has long recognized that increasing injection pressure to 500+ bar could substantially cut engine-out particulates while improving CO2 emissions and fuel economy.”

With the new Delphi Technologies system, engine designers can benefit from 500+ bar injection pressures without having to make costly changes to the majority of existing camshaft drive systems, the company informed.

Mr Piock said that “By designing an innovative new internal sealing system for our GFP3 500+ bar pump, in some applications, we have designed a downsized plunger diameter which prevents increasing the loads in the drive mechanism.”

To complete the new 500+ bar system, Delphi Technologies has developed all system components including Multec 16 injectors, pumps, forged rail as well as the appropriate engine control system and software.

These components, which further improve durability and reliability, also require no or only minor physical changes to existing engines because they match existing packaging constraints and interfaces. The 500+ bar system could be used in production from 2022 onwards.
