Peugeot Race Cars Incorporate Delphi Technology
Peugeot's two RCZ race cars, due to compete in the 2011 ADAC 24-hour event and the D1T category of the 10-race VLN championship, rely on standard Delphi fuel injection systems and powertrain cooling. The two team cars are powered by Peugeot's 2.0-litre HDi diesel engines with Delphi's fuel injection systems and powertrain cooling technology. Last year, the two Peugeot RCZs achieved a first and third in class at the ADAC 24-hour endurance race, winning against more highly modified cars and demonstrating good reliability.
This year's cars will essentially use the same specification as the 2010 cars but with a few modifications, including new wheels, brakes, tyres and aerodynamics. In addition, vehicle weight has been reduced to about 1,150kg. 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. Even with this extra boost, Peugeot has validated the production Delphi charge air coolers and compact aluminium radiators to meet the demanding performance specifications. Fuelling is provided by Delphi's production 2,000bar common rail system with Multec balanced-valve fast servo-solenoid injectors.
The only significant upgrade required was to change the nozzle definition, optimising the spray pattern to suit the increased swirl created by the higher boost levels. The revised configuration also increases maximum fuel flow, contributing to the increase in power and torque. The standard fuel pump is retained without modification, as is the ECU. Delphi modified the ECU software to allow Peugeot to recalibrate the engine mapping to suit the demands of endurance racing with the retuned engine.
