In the motorcycles area, we have made further progress in expanding the use of 4-stroke engines to give cleaner exhaust emissions. We have also made efforts to introduce new technologies to improve fuel economy. Our environmental commitment has also focused on reducing the use of harmful substances such as lead. |

Progress in the Targets to be Achieved by 2005 for Cleaner Exhaust Gases
|
|
|
|
|
 |
|
 |
|
|
|
 |
Up to fiscal 2005 : To reduce total exhaust emissions of HC* to approximately 1/3 for new vehicles (compared with fiscal 1995) |
|
|
|
| * |
Total for Japan, the US, the EU, and Thailand |

|
In fiscal 2001, the percentage of 4-stroke motorcycles in Japan from all motorcycles manufactured by Honda increased to 69.1%, and as a result, HC emissions from new Honda motorcycles were reduced to approximately 1/4 of the level in 1995 (down by approximately 76%). Accordingly, overall HC emissions from Honda motorcycles in Japan were reduced to approximately 20% of the fiscal 1995 level. |

1. Improvements in Emission Performance of HondaÕs Main Models

GOLD WING |
|
|
|
|
|
|
The GOLD WING, a new model released in August 2001 and the VFR, released in January 2002, both reached clean emission levels equal to 1/10 (CO and HC) and 1/4 (NOx) of the exhaust emissions standards of Japan. This was achieved by adopting the following technologies.
· Use of a ternary catalytic converter, the HECS3*1
· Use of PGM-FI (an electronic fuel injection system)
· Air injection system*2 (a secondary air induction system)
|
|
| *1 |
Honda Evolutionary Catalyzing System 3 |
| *2 |
To enhance the exhaust gas cleaning performance of motorcycles, this system adds external air to the exhaust gas from the engineÕs combustion chamber so as to combust the unburned gases and thereby reduce the residual levels of carbon monoxide (CO) and hydrocarbons (HC). |
