 |
To increase the number of vehicles approved
by the Ministry of Land, Infrastructure and Transport as “ low
emission vehicles” and “ low
emission vehicles” |
|
Achieved compliance of all vehicles with 2005
exhaust emissions regulations Another 10 types of 3 models approved as “ low
emission vehicles” and “ low
emission vehicles”(48 types of 21 models approved in total) |
|
|
To improve average fuel economy for all vehicle weight categories as defined in the fiscal 2010 fuel economy standards | |
Attained the fuel economy standards for fiscal 2010 for all the categories | |
* In order to give greater impetus to the use
of low emission vehicles, the Ministry of Land, Infrastructure
and Transport of Japan has instituted this approval system. Low
emission vehicles with HC and Nox emission levels below the 2005
exhaust emission standards are classified into two categories for
approval.
75% lower than the 2005 exhaust emission standards: “ low
emission vehicles”
50% lower than the 2005 exhaust emission standards: “ low
emission vehicles”
75% lower than the 2005 exhaust emission standards: “
low
emission vehicles”50% lower than the 2005 exhaust emission standards: “
low
emission vehicles”Achieving Cleaner Exhaust Gas
Progress towards Targets to Be
Achieved by 2005 with Cleaner Exhaust Gas
Note: In fiscal 2003, when a new low emission vehicle approval scheme under the 2005 exhaust emissions standards was introduced, total emissions of HC and NOx of those models subject to the 2000 exhaust emissions standards and older models were computed and totaled using the 10-15 mode, and total emissions of HC and NOx of those models subject to the 2005 exhaust emissions standards were computed and totaled using the new test mode for the 2005 regulations. For those models subject to the 2005 exhaust emissions standards, total emissions of HC are computed in non-methane hydrocarbon (NMHC).
Note: Because a new low emission vehicle approval scheme under the 2005 exhaust emissions standards was introduced on October 1, 2003, the numbers approved under the 2000 exhaust emissions standards and under the 2005 exhaust emissions standards are both indicated.
1. Honda LEV: All vehicles equipped with low emission vehicle (LEV) engines developed by Honda in 1996 and based on the Company’s own standards.
2. In order to give greater impetus to the use of low emission vehicles, the Ministry of Land, Infrastructure and Transport of Japan has instituted this approval system. Low emission vehicles with HC and NOx emission levels below the 2000 exhaust emissions standards are classed into three categories for approval.
75% lower than the standards: “Ultra”
50% lower than the standards: “Excellent”
25% lower than the standards: “Good”
Note:

• Up to fiscal 2005: To reduce the total exhaust emissions
of HC and NOx by approximately 75% for new vehicles (compared
with fiscal 1995)1
• Up to fiscal 2005: To have almost all Honda passenger vehicles approved as “ low
emission vehicles” and “ low
emission vehicles”
• Up to fiscal 2005: To have almost all Honda passenger vehicles approved as “
low
emission vehicles” and “ low
emission vehicles” Progress
In fiscal 2004, the target of reducing the total exhaust emissions
of HC and NOx by 75% for new automobiles (compared with fiscal
1995) was achieved, as in fiscal 2003.
• Total HC emission level: Reduced approx. 86.0% (compared with 1995)2
• Total NOx emission level: Reduced approx. 86.0% (compared with 1995)2
Since fiscal 2003, Honda had been promoting the earlier compliance of all its models with the 2005 exhaust emissions standards and made all the models comply with the standards. Honda is promoting the approval of its models as “ low
emission vehicles” and “ low
emission vehicles.”
• As of the end of March 2005, 27 types of 13 models were approved as “ low
emission vehicles and 21 types of 11 models were approved as “ low
emission vehicles.”
• Total HC emission level: Reduced approx. 86.0% (compared with 1995)2
• Total NOx emission level: Reduced approx. 86.0% (compared with 1995)2

Models/Types and Sales Results for Honda LEVs and Vehicles Approved as Low Emission Vehicles by the Ministry of Land, Infrastructure and Transport of Japan
Honda has endeavored to expand the number of its models that
meet the 2005 exhaust emissions standards and are approved by the
Ministry of Land, Infrastructure and Transport as low emission
vehicles. For the three models introduced in fiscal 2004 (the Elysion,
the Legend, and the Edix), all types of the Elysion and Legend
models and some types of the Edix model were approved as “ low
emission vehicles.” Also, some types of the Edix model were
approved as “ low
emission vehicles.”
Unit sales of Honda models that meet the 2005 exhaust emissions standards of the Ministry of Land, Infrastructure and Transport and are approved as low emission vehicles came to 583,871 in fiscal 2004, accounting for 81.4% of Honda’s total domestic unit sales (80.5% of the unit sales of passenger cars).
Notes:
1. Figures quoted for the years prior to the establishment of the Low Emission Vehicles’ Approval System of Japan (FY 1998–1999) refer to Honda LEV conforming vehicles.
2. For fiscal 2004, only the sales of vehicles that meet the 2005 exhaust emissions standards and are approved as low emission vehicles are shown.

Improvement in the Emission Performance of Honda’s Main Models
Legend
low
emission vehicle” by the Ministry of Land, Infrastructure
and Transport. Its porous atomizing fuel injector and electric EGR system contribute to higher combustion efficiency and lead to cleaner exhaust gas. Also, by adopting an integrated cylinder head and exhaust manifold as well as a catalytic converter attached directly below the cylinder head, the heat loss of the combustion gas has been reduced, and the catalytic converter can be promptly activated. Also, thanks to the precise control of the air-fuel ratio, the cleaning performance of the catalytic converter can be maximized even immediately after a cold start, thereby achieving an extremely clean performance.
