Pressure Charging at IP

• Tomorrows low CO2 powertrains demand outstanding
  boosting systems.
• We offer a full range of services to help our OEM
  and tier 1 customers to deliver ranging from
  design and manufacture of completely new
  technologies to the execution of turn-key
  projects for serial production.
• The following slides illustrate our approach

The Drive Feel Issue
Driving behaviour is fundamental to successful
downsizing

• Delay followed by rapid increase in acceleration
  (jerk) is difficult to control and perceived as
  unrefined
• Driver requires a minimum level of performance to
  be accessible without perceived delay in order to
  maintain desired trajectory (e.g. gradient, catch
  up vehicle in front etc). Thus poor response
  requires either
• Shorter gearing
• Driver selects lower gear for a given condition

This effect can reduce downsizing benefits by
more than 50

State of Art Thermodynamics(Gasoline)

• Low speed torque extension
• Variable cam phasing DI injection
  optimal gas dynamics
• Reduced EGR
• Reduced charge temperature
• Very high volumetric efficiency(gt1)
• Excellent knocking performance
• Avoidance of surge condition
• gt20 reduction of Tmax speed
• Solutions with twin scroll and pulse converter

• Emissions
• Fuel management
• ?1 exhaust, ?lt1 in-cylinder
• Late injection for catalyst warm-up
• Cooled EGR lean burn technologies
