Current Environmental Initiatives
At Keihin, we are actively conducting environmental activities in areas such as product development and purchasing, manufacturing and shipping. This section presents some of those activities.
■ Product Development
Hybrid cars are currently drawing a lot of attention as environmentally friendly vehicles. Our electronic control products and fuel supply products are used in the CR-Z hybrid vehicle launched by Honda in February 2010.
Main products used in Honda CR-Z
Engine Control ECU
VTEC Spool Valve
Hydraulic Pressure Control BODY for CVT (three types)
Throttle Body
Injector
Compressor
Comparison of fuel efficiency of engines of the same product family
| CR-Z | Fit | |
|---|---|---|
| Fuel efficiency | 25 km/L | 24km/L |
(10-15 mode fuel efficiency)
■ Shipping
We are also promoting environmental initiatives in product shipping. In fiscal 2009, we succeeded in reducing the use of PVC materials by improving the injector packaging.
Example of improvements in packaging for goods shipped overseas
When shipping injectors overseas, we changed from a conventional packaging method of attaching caps to each item to prevent foreign matter from entering the product to a method of preventing entry of foreign matter without using caps by withdrawing the air from the bag wrapping the injector to leave the product tightly sealed, leading to a reduction in PVC use.
Conventional
Improved
Reduction of PVC use
| Reduction of PVC use | Weight |
|---|---|
| 2,566,000 pcs | 2.6 t |
■ Manufacturing
We have a variety of initiatives for reducing CO2, energy consumption, and water consumption at manufacturing sites.
In fiscal 2009, we reduced CO2 by compressor control improvements and improvements such as making use of waste heat from air compressors.
Compressor Control Improvements
We achieved an energy saving from aggregation of compressor pressure control systems and centralized control of auxiliary equipment (cooling water pumps, cooling towers, etc.).
- ･Electric power savings
- 267 Mwh/year
- ･Cost-saving
- ¥ 3.6 million/year
- ･CO2 reductions
- 101 t/year
Use of waste heat from air compressors
Compressors were relocated into the factory and waste heat used for heating.
- ･Heavy oil reductions
- 7.84 KL/year
- ･Cost-saving
- ¥ 0.8 million/year
- ･CO2 reductions
- 21 t/year
