Waiver Approval By ETRP Waver No. E001-001 Valid From 01-Apr-11 Current Component Current Part Number Crankshaft 136 0177 Key Dimensions of current part Not relevant Weight and material of current part Cast steel crankshaft without full form radii on journals. Standard part weight is 13.32 kg Reason For Request Crank shaft unsuitable for 2013 performance target Justification The average peak cylinder pressure for 2013 is estimated to be approximate 130 bar. Our analysis shows the crank is likely to break in the area of the fillet radius of the crank pin due to material and geometry (fillet radi). We propose a forged steel crankshaft with full form fillet radii and manufactured from Corus 722M24 8 of 15
New Part Number E033/016 Key Dimensions of new part Pin and main bearing sizes identical to production crankshaft Weight and material of new part Corus 722M24 forged steel, similar weight to production part 9 of 15
Waiver Approval By ETRP Waver No. E 001-002 Valid From 01-Apr-11 Current Component Current Part Number Inlet manifold 137 65I0 Key Dimensions of current part Runner dimensions, lengths and plenum volume to suit normally aspirated application Weight and material of current part Plastic moulded construction 4.10 Kg Reason For Request Reliability and performance Justification The plastic construction is not reliable for turbocharged applications nor it can be robustly modified to mount boost sensors. The geometry is unsuitable for a turbocharged application (runners and plenum) 10 of 15
