Delphi Technology Reigns at Grueling Nürburgring Race
Standard road car technology from Delphi helps lead to Peugeot victory at Nürburgring 24 Hours race
WUPPERTAL, Germany – A virtually standard Delphi diesel fuel injection system powered the class-winning Peugeot RCZ at the recent Nürburgring 24 Hours race. Competing in a field of 201 vehicles the RCZ 2.0 liter HDi diesel coupé displayed consistent speed and reliability to dominate its class.
While many of the competing vehicles were highly modified for racing, Peugeot entered standard RCZ cars that were largely unmodified from the road-going versions. The road car specification RCZ completed 3,299.14 kilometers of what is universally perceived as the toughest racetrack in the world, the Nürburgring Nordschleife or ’Green Hell’.
“The Nürburgring Nordschleife is an ultimate endurance test of any car,” said John Fuerst, Delphi’s general manager, Diesel Engine Management Systems. “Our technical partnership with Peugeot in this race demonstrates that Delphi technologies are highly capable of meeting rigorous performance levels.”
The two RCZs ran in the D1T category for diesel cars between 1.7 liters and 2.0 liters. The key change to the standard engine is an increase in turbo boost pressure -- lifting the torque from 340Nm to 400Nm and the power from 120kW to 150kW.
Delphi’s original equipment charge air coolers and radiators were retained as they met the performance targets required for endurance racing.
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 modification required was to change the nozzle definition, optimizing the spray pattern to suit the increased swirl created by the higher boost levels. The new configuration also increased maximum fuel flow, contributing to the increase in power and torque. The standard fuel pump was retained without modification.
For a race car to use a production ECU is rare. But Delphi 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 a clear indication of the quality of Delphi technology and manufacturing,” Fuerst said. “Delphi congratulates Peugeot on their success at Nürburgring 2011.”
