Yanmar Certified by California Air Resources Board
July 2, 2012
Yanmar Co., Ltd.
In response to increased environmental awareness, recent years have seen the continuous tightening of emission regulations the world over. From 2013, both Europe and North America are planning to introduce even stricter standards to control nonroad diesel engines under 56kW.
In this regard, Yanmar is proud to announce that it is the first manufacturer in the world to have been certified by the California Air Resources Board (CARB) for diesel engines in the range 19 to 56kW, compliant with Tier 4 standards. Moreover, Yanmar has simultaneously received Tier 4 compliance certification from the Environmental Protection Agency (EPA).
Tier 4 regulations for engines in this range require that emissions of particulate matter and NOx be further reduced by about 90% compared to previous levels, positioning compliant items among the cleanest industrial diesel engines available.
1. Yanmar Certified Engines
| Model | 4TNV88C |
|---|---|
| Type | Vertical, water-cooled, 4-cycle, naturally-aspired diesel engine |
| Fuel Injection | Fully electronically-controlled common rail system |
| Displacement (l) | 2.2 |
| Rated Output (kW) | 35.5 |
| Date of certification | CARB: May 29, 2012 (Note: world’s first)EPA: June 15, 2012 |
2. Technologies Employed
To ensure compliance with the latest emission regulations, Yanmar has employed proprietary direct injection and electronic control technologies, along with an advanced common rail system and diesel particulate filter technologies. The combination of exhaust gas recirculation with advanced electronic control allows for a significant reduction in particulate matter and NOx emissions. Yanmar is thus able to deliver highly reliable engines of superior fuel efficiency, complying with the most rigorous regulations in force. These new technologies are the fruit of accumulated knowledge and ongoing development at Yanmar’s Maibara Research and Development Center, Japan, and concerted efforts Group-wide.
3. Future Undertakings
Yanmar has also been certified by CARB and EPA for engines under 19kW, and in 2012, the year we celebrate a century of operations, mass production begins at our Biwa Plant in Japan, towards providing world markets with highly efficient engines to be used in a wide array of industrial machinery.
