MAJOR DEVELOPMENTS FOR THE AUTOMOTIVE INDUSTRY FOR THE NEXT FIVE YEARS Luis Enrique Arimany
AUTOMOTIVE INDUSTRY STUDY • Highgrowth in the Diesel sales
3.Another market key points • Less manufacturers • Platforms • Modular cars • Extended enterprise
3. Emissions legislation Euro III: 1103 268D Euro IV: 208 no D • Euro III 2000 • Euro IV 2005 • Tier 2 2004-2007
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
Common-rail • No relation with speed • Independent control of : • Injection pressure • timing • quantity • Better performance: • specfic output (40) • fuel consumption (30) • noise
Common-rail (2) • Pump • Common pressure acumulator • Injectors/Solenoid • ECU
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
Lean burn / GDI • Higher Thermal efficiency • Higher compression ratio (12) • Higer volumetric efficiency
GDI • Upright straigh intake • Spherical cavity in piston • High pressure pump (15) • Stratified charge • Homogeneous charge
Hybrid cars • Drive 400 Km between re-fuelling • Be refuelled quickly and easily • Minimum performance (small engine) • Pollution
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
Elements Electrodes Membrane Electrolyte Catalysts Types: By electrolyte Solid Liquid Fuel cells
Fuel cells • By temperature: • Low temperature • High temperature Advantages: • H2 is clean? • Better efficiency
Variable cam timing Compromise between power, torque and idle. Some ideas: • Late IVC • Early EVO • Overlap: Early IVO & late EVC
Variable cam timing (2) • Infinitely valve timing • Operate outside cams • Operate middle cam (interconnected rockers)
VTEC-E Deactivates one valve High swirl Run lean (AFR=20) Camless Solenoid Control/ Maximum performance Instantaneous open Variable cam timing (3) / Camless
