We completed the adoption of 4-stroke engines to all models* to achieve cleaner exhaust gas and better fuel economy. We are now expanding the use of our electronically controlled fuel injection (FI) system to include small models and developing and applying other new technologies to mass-produced models.

* Except some special models

Main targets for fiscal 2004 in Japan		Main achievements in fiscal 2004 in Japan
	To expand the use of 4-stroke engines		Adopted 4-stroke engines for all models launched in fiscal 2004 (4-stroke motorcycles as a percentage of all motorcycles manufactured by Honda: 97.2%)*
	To improve the fuel economy of new models		Improved the average fuel economy by 34.2% for all models marketed in fiscal 2004*

Achieving Cleaner Exhaust Gas

Progress towards Targets to Be Achieved by 2005 with Cleaner Exhaust Gas

Targets

Up to fiscal 2005: To reduce total exhaust emissions of HC* to approximately 1/3 for new motorcycles (compared with fiscal 1995)

* Total for Japan, the United States, the European Union, and Thailand

Progress

In fiscal 2003, total HC emissions from new Honda vehicles increased by 3.3 points due to a large increase in the number of unit sales. In fiscal 2004, however, emissions decreased by 4.9 points compared with the 2003 level as a result of progress in technological development and application. We have thus reduced total emissions to approximately one-fourth of the 1995 level and have continuously achieved the target of reducing HC emissions to approximately one-third of the 1995 level every year since 2000.
In Japan, we completed the adoption of 4-stroke engines. Also, we expanded the use of our electronically controlled fuel injection (FI) system to include small models and developed and applied other new technologies to mass-produced models. As a result, total HC emissions in Japan dropped to approximately 13.3% of the 1995 level, down approximately 2.9 points from that in the previous year.

Improvement in Emission Performance of Honda’s Main Models

FORZA X

Honda promotes cleaner exhaust gases both in Japan and throughout the world. In fiscal 2004, we continued to apply electronically controlled fuel injection (FI) technology to small motorcycles to realize cleaner exhaust gases in 4-stroke engines.
In Europe, we launched the Zoomer, a 50 cc moped, as the first FI system-equipped moped in the region. The Zoomer has achieved clean emission levels equal to 1/2 or less of the Euro II emissions standards for CO and HC+NOx.
In Japan, we expanded the use of our FI system to medium-sized models in addition to large and small ones. The FORZA X (250 cc), which went on sale in April 2004, and the FORZA Z, which was launched in July of the same year, have both achieved 1/2 or less of the exhaust emissions standards in Japan for CO and HC.
