  1. Metaldyne response to Renault Samsung Motors Inquiry on BSM Engineering Development September 9, 2005

  2. Full Powertrain System Performance Testing • 300 hp continuous rating • 125 mph speed rating • Full powertrain motoring • 10,000 lb GVW • 125 Hz cut-off frequency • NC30 noise rating Nissan Frontier vehicle with TR2K Engine shown in Metaldyne’s vehicle hemi-anechoic chamber

  3. Engine / System Performance & Validation Testing Engine NVH Dynamometer Cell

  4. Balance Shaft Module Test Facilities • 6 fully enclosed BSM test cells. • Piped in oil delivery for safe changeovers. • Block construction for operator safety. • Closed test environment for noise, fire, and debris containment. • Supplementary tooling allows for specific program testing on any rig.

  5. Balance Shaft Module Rig Testing DVP Testing • Pre-shipment screening • Power Consumption • Oil Aeration / Purge Time • Reliability / Durability • Gear Backlash Sensitivity • Thermal Cycling • Housing Twist Sensitivity • Bearing Temperature • Housing Strain 7 BSM Durability & Performance Test Stands

  6. Component Noise Testing Open-air BSM Test Stand • Component noise analysis & optimization • Accelerometer versus microphone • Acoustic holography • Temperature sensitivity • Torsional excitation • NVH Benchmarking BSM NVH Test Cell

  7. Mounting Plate Right Mic (not shown) BSM Oil Intake Rear Mic Left Mic Oil Discharge M1G BSM NVH Benchmark testing on open-air test stand Test setup conditions • 0 to 4,000 RPM speed sweep • 65 RPM / second sweep rate • Oil pump system functional • No torsional excitation • 93° C oil temperature • Ambient test temperature M1G BSM mounted on Metaldyne Open-air BSM Test Stand

  8. Left (oil filter) side microphone NVH Benchmark comparison testing on open-air test stand dB (A) scale 45 - 80 dB (A) scale 45 - 80 Current Production Nissan M1G BSM Current Production Metaldyne 2.4L Gasoline Engine BSM • ~3.5 Kg-mm unbalance • 2 x ERPM oil pump • 3.73 Kg-mm unbalance • 2 x ERPM oil pump The proof is in the results . . .

  9. NVH Benchmark comparison testing on open-air test stand Right side microphone dB(A) scale 45 - 80 dB(A) scale 45 - 80 Current Production Nissan M1G BSM Current Production Metaldyne 2.4L Gasoline Engine BSM • ~3.5 Kg-mm unbalance • 2 x ERPM oil pump • 3.73 Kg-mm unbalance • 2 x ERPM oil pump The proof is in the results . . .
