  1. MAJOR DEVELOPMENTS FOR THE AUTOMOTIVE INDUSTRY FOR THE NEXT FIVE YEARS Luis Enrique Arimany

  2. AUTOMOTIVE INDUSTRY STUDY • Highgrowth in the Diesel sales

  3. 2. Shrink of upper-medium segment

  4. 3.Another market key points • Less manufacturers • Platforms • Modular cars • Extended enterprise

  5. 3. Emissions legislation Euro III: 1103 268D Euro IV: 208 no D • Euro III 2000 • Euro IV 2005 • Tier 2 2004-2007

  6. Important developments • Common Rail • EGR • VGT • Lean burn • 3 litre car • Variable cam timing / Camless • Hybrid • Fuel Cells • NOx Traps • 42 volts • New fuels • Active suspension • SC, TC, ABS

  7. Common-rail • No relation with speed • Independent control of : • Injection pressure • timing • quantity • Better performance: • specfic output (40) • fuel consumption (30) • noise

  8. Common-rail (2) • Pump • Common pressure acumulator • Injectors/Solenoid • ECU

  9. 3 litre car • Lean burn • Hybrid cars • Small engine • TDI • CO2 emmisions • Fuel economy. • How: • Light weight • Friction reduction • Aerodynamic drag • Rolling resistance • Engine performance

  10. Lean burn / GDI • Higher Thermal efficiency • Higher compression ratio (12) • Higer volumetric efficiency

  11. GDI • Upright straigh intake • Spherical cavity in piston • High pressure pump (15) • Stratified charge • Homogeneous charge

  12. Hybrid cars • Drive 400 Km between re-fuelling • Be refuelled quickly and easily • Minimum performance (small engine) • Pollution

  13. Hybrid cars (2) • Recover energy in the battery when braking • Shut of the engine when not need • Reduce emissions • E.g.: Honda Insight and Toyota Prius

  14. Elements Electrodes Membrane Electrolyte Catalysts Types: By electrolyte Solid Liquid Fuel cells

  15. Fuel cells • By temperature: • Low temperature • High temperature Advantages: • H2 is clean? • Better efficiency

  16. Variable cam timing Compromise between power, torque and idle. Some ideas: • Late IVC • Early EVO • Overlap: Early IVO & late EVC

  17. Variable cam timing (2) • Infinitely valve timing • Operate outside cams • Operate middle cam (interconnected rockers)

  18. VTEC-E Deactivates one valve High swirl Run lean (AFR=20) Camless Solenoid Control/ Maximum performance Instantaneous open Variable cam timing (3) / Camless

  19. VGT and EGR
