| OVERVIEW |
In fiscal 2005, DENSO further developed its supply network for
powertrain products. In China the Company established three new manufacturing
companies to produce fuel injectors and fuel injection pumps for gasoline vehicles,
ignition coils and filters. In Europe, DENSO started production of intake manifolds
and air filters in Poland, and established an engineering center for diesel engine
components in Germany. In the Republic of Korea, DENSO started production of stick
coils and variable cam timing (VCT) components. In the United States, DENSO increased
production capacity for exhaust gas sensors, ceramic substrates and fuel injectors.
In Mexico, the Company expanded capacity for VCT components and oil flow control
valves (OCVs) and established new production lines for evaporative leak check
modules (ELCMs) and non-contact sensors.
On the sales front, DENSO began delivering components for Toyota’s
IMV project, including diesel common rail systems (CRS), and fuel injectors, fuel
pump modules, stick coils and exhaust gas sensors for gasoline vehicles. The company
now delivers common rail systems to Isuzu Motors Limited in the ASEAN region,
and started contract production of main inverters for Toyota’s hybrid
electric vehicles (HEVs).
Overall trends in this segment include strong sales of CRS in the
ASEAN region and Europe, while variable valve-timing systems sold well globally.
In the Japanese and American markets there was growth in integrated air fuel modules,
automatic transmission (AT) control products and ELCMs. Increased sales of discharge
lamp ballasts and components for HEVs in Japan also improved overall performance. |

| PERSPECTIVE |
Automakers are seeking to increase fuel-efficiency and lower
emissions to meet increasingly stringent standards in markets worldwide. DENSO
plans to meet this need by developing components and systems for gasoline engine,
diesel engine, and HEVs.
In Europe, where around half of vehicles are diesel powered, the drive
to lower CO2 emissions favors diesel engines. In North
America, use of diesel engines is likely to increase, especially for SUVs, in
the face of more stringent Corporate Average Fuel Economy (CAFE) standards. Automakers
in both markets face the challenge of future regulations that call for further
reduction of nitrogen oxide (NOx), particulate matter (PM) and other harmful substances
in the exhaust gas. In Japan, automakers must prepare for regulations that may
soon set diesel PM emissions at the same level as for gasoline engines. DENSO’s
market-leading diesel CRS brings major improvements in fuel efficiency while lowering
PM and NOx emissions and increasing drivability (see Technological Development,
page 9). DENSO continues further development on even more advanced CRS, capable
of reducing harmful substances in the exhaust gas even further.
HEVs are gaining U.S. and Japanese market share thanks to tax incentives
and improved acceleration performance. Depending on the strictness of CO2
emission regulations in 2012, HEVs could also claim a bigger share in Europe.
DENSO’s products for HEVs include battery ECUs, DC-DC converters, inverters,
and electric-motor driven car air-conditioning systems. DENSO research is further
reducing the size and improving the efficiency of these components. |
