  1. INGAS Subproject SPA2 18 Month Meeting Paris, Subproject A2, Status (month 13-18) Dr. Michael Höge, Siemens AG

  2. INGAS Subproject SPA2 • A2.2.2 – Gen2 with doublestack and membrane sealed bellows: Procurement, assembly and laboratory tests of Gen2 double stack drive mechanism Test results: => Injector shows stable behavior over runtime 8 injectors delivered to MBTech for commissioning of third engine => Injectors failed due to leakage of stroke amplifier Mechanical redesign of stroke amplifier: Laboratory tests: => Injector shows stable behavior over runtime 6 injectors delivered to AVL for testing => Injectors failed due to leakage of stroke amplifier

  3. INGAS Subproject SPA2 • A2.2.2 – Gen2 with doublestack and metal sealed bellows + Functionality proofed with demonstrator at laboratory + Dimensions suitable for engine + Thermal compensation of oil volume possible Hydraulic oil Big bellow Small bellow Demonstrator of metal sealed stroke amplifier

  4. INGAS Subproject SPA2 • A2.2.2 – Gen2 with doublestack and metal sealed bellows Stroke amplifier with bellows Timeline Concept: done Design: done Purchase: mid June Assembly: mid July Test @ Siemens and shipment to AVL: end July

  5. INGAS Subproject SPA2 • A2.2.2 – Direct - Gen2 for commissioning first car Stroke amplifier replaced by spacer Material of spacer is aluminum to compensate thermal differences as much as possible Gen2 nozzle Timeline Concept: done Design: done Purchase: done Assembly: done Test @ Siemens: done Shipment to AVL: 18.05.2010

  6. INGAS Subproject SPA2 • A2.2.2 – Direct - Gen2 for commissioning first car Example of measurement results at 23°C Example of measurement results at 80°C 86um 67um
