Delphi's powertrain technologies include multi-point injection and direct injection gasoline systems, common rail, rotary pump diesel systems in a range of capacities and, for heavy-duty diesel applications, electronic unit injectors and electronic unit pumps. Delphi was the first to develop a solenoid injector that challenges the performance of servo piezo injection systems and the first to introduce closed loop control for diesel. It has been a successful strategy that has helped the company grow steadily to become the world's second largest supplier of diesel common rail systems, behind Bosch. Matthew Beecham talked to Dr Sebastian Schilling, engineering director, Europe, Gasoline EMS & Powertrain Products, Delphi, and Philippe Bercher, deputy director, Diesel Engineering, Delphi
