The first win for Truck Race Team Rainbow Warrior during Easter races at Zandvoort with a great lead.
Scania Race Team from Zwolle has in recent months been working very hard on the race truck to stiffen things up as the engine torque was lifting the rear wheel in the corners.
After the Daf Euro 6 project we did find more torque by adding more injection or rail pressure in combination with bust injection I also try this on the Scania XPI engine and it worked well.
We also start using post injection as we are very close to the max commonrail pressure and as the fuel metering is very aggressive it’s not that hard to open the safety valve on the commonrail as the fuel metering valve on the hi pressure fuel pump can not shut off fuel that fast (in milliseconds) so to prevent this we use post injections to drop the fuel pressure rapid by injecting fuel into the exhaust keeping the EGT up as while the engine deliver no power giving better turbo spool-up in the process as well.
Knowledge is power, so we have measured data from the Adaptronic Diesel ECU and AIM display / data logger and a RaceCapturePro data logger / speed module for GPS speed control (maximum speed limit) and so know what's going on every part of the track.
