A Defining Moment

• DENSO has revised its forecast for FY 08
• Sales will be lower
• This is an opportunity to approach everything we
  do with a fresh perspective

4
Committed to Our Customers

• DENSO has a long history here
• Sold first product in 1964
• 25 manufacturing plants operating in North
  America today

5
Future Growth

• Depends on innovative technology
• Investigate new ways to meet customer, society
  needs

Automotive Industrys Issue

• Concerns of global warming and oil consumption
  will further accelerate
• Developing environmentally friendly vehicles that
  consume less fuel and emit fewer CO2 emissions is
  a big issue facing the automotive industry today

DENSOs Main Areas

• Make products, smaller, lighter and more
  efficient
• Improve the efficiency of combustion engines
  Gasoline and Diesel
• Improve energy management
• Increase technology for hybridization idle stop
  and start, and hybrid vehicle systems

13
New Air Conditioning System

• This year, plan to launch a new air conditioning
  system for passenger cars, using ejector
  technology

• Result of continued work on the worlds first
  refrigeration unit using an ejector cycle
  introduced in 2003

Ejector cycle introduced in 2003
14
Advantages of new system

• Reduced size of the ejector and improved
  installation
• Enable to reduce systems fuel use by 30 to 40
  percent at maximum depending on conditions

18
Gasoline Direct Injection System

• Achieve the the worlds smallest fuel particle
  spray about 10 to 15 microns
• Provide an optimal spray for combustion

19
200MPa Diesel Common Rail System

• Introduced 200MPa Common Rail System in Europe
• Available for piezo and solenoid injectors
• Plan to be introduced worldwide by 2010

20
DENSOs Main Areas

• Make products, smaller, lighter and more
  efficient
• Improve the efficiency of combustion engines
  Gasoline and Diesel
• Improve energy management
• Increase technology for hybridization idle stop
  and start, and hybrid vehicle systems

21
Energy Management

• Our unique approach to reduce, recover, reuse
  fuel energy lost or not used for driving

22
DENPI - developed by DENSO

• DENPI is an index to optimize fuel used in
  generating a vehicles electrical power
• Better management of the alternators charge
  results in less fuel consumption

23
Cold Storage System

• Our engineers in various areas are developing
  together
• Houses cold energy and directs it as needed to
  the cabin when the engine powers down such as at
  idle stop
