“Delphi’s production 2000 bar common rail system with Multec balanced-valve fast servo-solenoid injectors met the modified engines’ demands with minimal revisions. Extensive trials established that the only significant upgrade required was to change the nozzle definition, optimizing the spray pattern to suit the increased swirl created by the higher boost levels. The standard fuel pump was retained without modification,” stated the press release
The two 2.0 liter HDi diesel RCZs were largely unmodified from the road-going versions, to demonstrate the reserves of performance and durability of the Peugeot regular production vehicles. However, the cars, which competed in the D1T category for diesel cars between 1.7 and 2.0 liters, featured an increase in turbo boost pressure, which brought its torque up from 340 to 400 Nm and the power up from 163 to 204 hp.
“This event has been called the ultimate durability test,” said John Fuerst, Delphi’s general manager, diesel engine management systems. “Delphi successfully faced this test with production products on the RCZs that needed little or no modifications to perform in this grueling race. We are delighted to have been selected as a technical partner for Peugeot and to have helped them achieve such an impressive result in the company’s 200th anniversary year.”
"For a race car to use a production ECU is a particularly rare event but Delphi achieved this as well,” Fuerst added. “Our technical specialists modified the software of the standard ECU to allow Peugeot to re-calibrate the engine mapping to suit the demands of endurance racing with the re-tuned engine. To meet the challenges of such a gruelling race with systems that were originally designed for road car applications is very satisfying for us and is a clear indication of the quality of Delphi technology and manufacturing. I’d like to congratulate Peugeot on their success in this demanding event.”
