Title: Modern Engine Technology


1
Modern Engine Technology
  • CHE 384
  • Ted Kane
  • 17 November 2005

2
Modern Engine Technology
  • Engine Technology
  • PFI
  • GDI
  • Advanced Diesel
  • HEDGE
  • Modeling Tools
  • Federal Regulations
  • Passenger Cars
  • Heavy-Duty Trucks

3
Port Fuel Injection
  • Allows more precise fuel/air mixture control
  • Allows the use of the the 3-way Catalyst
  • Provides a 96 reduction in HC and CO
  • Provides a 88 reduction in NOx
  • Typically about 34 peak efficiency

4
Gasoline Direct Injection
  • Provides more flexibility with fuel injection
    timing
  • 20 Fuel Economy Increase over PFI
  • Engine out emissions are better than PFI
  • Tailpipe Emissions are worse than PFI
  • Produces Particulate Matter

5
Advanced Diesel Control
  • Required to meet 2007 Standards
  • Particulate Filters
  • Lean NOx Catalyst
  • Drops peak efficiency to 37

6
Advanced Diesel Schematic
7
HEDGE
  • High Efficiency Durable Gasoline Engine
  • High Compression Otto Cycle Engine
  • Can attain Diesel Like Efficiency (40)

8
HEDGE Flow Schematic
9
HEDGE Operation
10
Diesel vs Otto
11
EPA Car Emission Standards
12
EPA Truck Emissions Standards
13
EPA Truck Emissions Standards
14
Modeling
  • DOE ANL Transportation Technology
  • GREET
  • PSAT
  • Combined to provide Well-to-Wheel Estimate of
    emissions and fuel economy

15
GREET(Greenhouse Gases, Regulated Emissions, and
Energy Use in Transportation)
  • Well-to-Pump Emissions Tool

16
GREET(Greenhouse Gases, Regulated Emissions, and
Energy Use in Transportation)
17
PSAT(Powertrain System Analysis Toolkit)
  • Produced by ANL
  • Allows for simulated emissions test drive cycles
  • Can be converted into prototype control system
  • Pump-to-Wheel Emissions Estimates

18
University of Texas Involvement
  • Sponsored by ANL and GM
  • UT Attempting to implement first HEDGE engine in
    a vehicle
  • Potential 40 increase in Fuel Economy
  • Potential to meet 2006 Tier 2 standards

19
Conclusion
  • Engine Technology has greatly reduced emissions
    leading to Ozone and CO
  • Modeling allows designers to analyze full system
    impact, while reducing cycle time and including
    Wheel-to-Well emissions
  • Government regulations continue to drive
    technology
