Delphi Technologies was an independent automotive company from 2017 to 2020, when it was acquired by BorgWarner Inc. As of 5 July 2023, BorgWarner completed the spin-off of Delphi Technologies, Delco Remy, and Hartridge to a separate publicly traded company, PHINIA.
In 2008, a DOE sponsored partnership between Delphi Electronics and Peterbilt demonstrated that a fuel cell could provide power to the electronics and air conditioning of a Peterbilt Model 386 under simulated "idling" conditions for 10 hours. This solid oxide fuel cell can directly accept diesel [6] using an integrated endothermic reformer. [7]
The Unit Pump system [1] is a modular high-pressure diesel injection system, which is closely related to the unit Injector system, and is designed for use in commercial vehicle diesel engines. [ 2 ] The systems use an individual injection pump mounted on the engine block for each cylinder so it is primarily designed for OHV or "cam in the block ...
Common rail fuel system on a Volvo truck engine. In 1916 Vickers pioneered the use of mechanical common rail systems in G-class submarine engines. For every 90° of rotation, four plunger pumps allowed a constant injection pressure of 3,000 pounds per square inch (210 bar; 21 MPa), with fuel delivery to individual cylinders being shut off by valves in the injector lines.

In 2002, ongoing financial problems caused the plant to be placed in the Automotive Holdings Group, a collection of under performing plants that Delphi felt needed to be fixed, sold, or closed. Delphi declared bankruptcy in October 2005, and announced plans to close or sell 21 of its 29 US plants by Jan 1, 2008, including Flint East.
The constant stroke pump element on the way up draws fuel from the supply duct in to the chamber, and as long as the electric solenoid valve remains de-energized the fuel line is open. Spill phase The pump element is on the way down, and as long as the solenoid valve remains de-energized the fuel line is open and fuel flows in into the return duct.
On May 28, 1999, Delphi became a separate publicly traded company, and continued to use the Delco Electronics name for several of its subsidiaries until 2004. Although Delco Electronics no longer exists as an operating company, GM still retains rights to the "Delco" name and uses it for some of its subsidiaries including the ACDelco parts division.
EEC-III on carbureted cars controlled the same Ford 7200 VV carburetor as the EEC-II. On fuel-injected cars, the module fired two high pressure (approximately 40 psi) fuel injectors that were mounted in a throttle body attached to a traditional intake manifold in the center valley of the 5.0 liter (302 cid) engine.
