Kubota Diesel Engines Between 56 and 130kW Receive Certification for CARB Tier 4 Final Emissions Regulations

The next emissions regulations for non-road diesel engines with an output range between 56 and 130 kW will come into effect in North America in January 2015. Kubota's non-road diesel engines between 56 and 130 kW are in compliance with the latest emission regulations. These engines have been certified by the U.S. Environmental Protection Agency (EPA) and the European Union (EU) and most recently by the California Air Resources Board (CARB). These engines will be installed in Kubota brand tractors and construction machinery. The engines for non-captive product will also be available for construction and industrial machinery. Mass production will start from October 2014.

Tier 4 Final and Stage IV are very stringent emission regulations. They require NOx (nitrogen oxide) reduction by about 90% in comparison with the current regulations. Kubota has adopted selective catalytic reduction (SCR) for NOx reduction. Together with the Diesel Particulate Filter (DPF) and Diesel Oxidation Catalyst (DOC), Kubota has developed the integrated technology and system to comply with the latest regulations. Kubota has maintained its compact design with these new engine models and in some cases has even increased the output compared to previous engine models.

Kubota Engine America Donates a Diesel Generator to the Science Barge

Kubota Engine America has donated a GL7000-USA Lowboy generator to the Science Barge located on the Yonkers, New York side of the Hudson River.  Due to the very rough winter the generator that the Science Barge had was damaged so they were in need of a new generator.  Mr. Bob Walters, the “captain” of the barge reached out to Kubota Engine America and explained their cause and current need. Kubota felt that the Science Barge was a great representation of our brand statement, For Earth, For Life, linking food, water and the environment.

The Science Barge is a prototype sustainable urban farm developed by NY Sun Works and acquired by Groundwork Hudson Valley in October, 2008.  It is operated as an environmental education center featuring a greenhouse and stations teaching students the basics of hydroponics and renewable energy. The Science Barge grows an abundance of fresh produce with zero net carbon emissions, zero pesticides, and zero runoff for our Get Fresh Yonkers Farmers Market, helping to improve access to fresh vegetables in this community where they are not readily available.

All of the energy needed to power the Barge is generated by 85% solar panels and 15% wind turbines and irrigated solely by collected rainwater and purified river water, thus operating completely “off the grid.”  When there is not enough solar power or wind power generated the Kubota GL7000-USA Lowboy will be used as a back up to power the barge. 

​In 2013, the​ Science Barge sees over 3,000 visitors per year, including tourists from 15 different countries​.  For further information about the Science Barge please visit their website athttp://www.groundworkhv.org/programs/science-barge/.

Kubota Engines Certified EPA Tier 4 / EU Stage IIIB Emission Standards

With increasing awareness towards the conservation of the global environment, Kubota always places a top priority on ensuring environmental compatibility as well as reducing the environmental impact.

The next emissions standards for Non-Road diesel engines with an output range below 56 kW will come into enforcement in 2013 in North America, Europe and Japan. In order to assure product readiness from the beginning of the new standards, Kubota has initiated the certification application process from early 2012.

After receiving the first approval from EPA*1 on May 7th, we are now proud to announce that Kubota has received certification approval from EPA, CARB*2 and EU regulatory authorities on all engine series with an output range below 56kW.

With this achievement as well as previously obtained emission certification for engines between 56kW and 130kW, we are now ready to introduce the full engine line-up of Kubota Compact Diesel Engines which meet EPA/CARB Tier4 and EU Stage IIIB standards.

*2…CARB: California Air Resources Board

Certification Summary
1) Certified Date: May 2012 – Oct 2012
2) Certified Models: Industrial Diesel Engines
3) Certification Organization:
EPA, CARB (below 56kW)
EU Stage IIIB (37 to 56kW)

Kubota's Compliance with Tier 4 Emissions Regulations
Tier 4 and Stage IIIB are extremely stringent standards. The new standards require further reduction of particulate matter (diesel soot) by 90% in comparison to the previous standards.

In order to comply with the new standards, Kubota utilized a variety of technologies such as Common Rail System, an electronic fuel injection system, for optimization of combustion processes, Exhaust-Gas-Recirculation Device (EGR)*3 and Diesel Particulate Filter (DPF)*4 for improvement of emission performance . These technologies will bring more durable, quieter and fuel efficient engines with minimal impact to the engine package for ease of installation into OEMs machines.

In additional to the above, Kubota also developed and introduced a new emission-compliant diesel engine (engine output range between 19 – 37kW), which utilizes Kubota’s proprietary “TVCS”*5 combustion system and unique DPF regeneration system.

Kubota also obtained EPA and CARB certifications for diesel engines with an output range below 19kW. Of special note is that Kubota obtained the emission certifications without adding new devices, but with further optimization and improvement of existing technologies.

With the introduction of these newly developed diesel engines, Kubota is confident to satisfy both the emission standards as well as the markets’ wide-variety and challenging demands.

Production of these new emission certified engines will begin in October 2012 for use in Kubota branded agricultural and construction machinery as well as OEM’s equipment such as construction machines, gen-sets, welders and other industrial applications.
