Kubota Launches a New Spark Ignited Engine

Kubota has added the WG3800 to the WG series, a series of industrial based water cooled gas/gasoline engines. The WG3800 offers a 3.8 liter displacement and mass production will begin February of this year. The fuel options offered will be LPG, gasoline, natural gas and a dual fuel version. This engine will be supplied to manufacturers for construction and industrial equipment. 

As the awareness for the conservation of the global environment has increased, emission standards for industrial engines have become more stringent.  All industrial equipment manufacturers are now required to use emission certified engines. Kubota has taken measures to comply with the various emission requirements in designing the gas/gasoline engine.  Kubota’s “WG series” has the same industrial footprint as the diesel lineup.  The displacement ranges from 0.74L to 2.5L, and now adding the 3.8L with WG3800. With the addition of this new engine, we offer a wide range of gas/gasoline engines to construction and industrial equipment manufacturer for use in various applications such as forklifts and generators.

Emission Certification 

Kubota has developed the WG3800 meeting the latest emission regulations in the United States, Europe, and Japan. Based on our V3800 diesel engine, we have developed a combustion chamber, fuel and ignition system dedicated for gas/gasoline. With a three-way catalyst, the engine is certified by the U.S. Environmental Protection Agency (EPA) Non-Road SI Tier 2 and California Air Resources Board (CARB) Non-Road SI Tier 3. (*1)

(*1)The LPG version is certified. The natural gas, gasoline, and dual fuel version will be certified soon.

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.

Certified date:  
July 30, 2014

Certification organization:
California Air Resources Board (CARB)

Certified Models (Industrial liquid cooled diesel engine with ouput range of 56 and 130 kW):     
(1) 3.8 Liter, Turbo inter-cooled for V3800 
(2) 6.1 Liter, Turbo inter-cooled for V6108

Note: These diesel engine models were certified by EPA, Tier 4 Final on July 17 and European Union, Stage IV on June 30.

Kubota Expands Diesel Engine Line-Up by Adding New Diesel Oxidation Catalyst (DOC) Only Option (19-56kW)

As the awareness for the conservation of the global environment has increased, emission standards for industrial engines have become more stringent. Kubota has taken measures to reduce emissions by first introducing engines utilizing Diesel Particulate Filter (DPF) as the after-treatment device.

Today we are pleased to announce that Kubota has introduced 4 new diesel engine models with Diesel Oxidation Catalyst (DOC) only from 19kW to 56kW. This further expands the Tier 4 Final line-up providing the customer additional engine options and flexibility in choosing the right engine for their application. These 4 new engine models are certified by the U.S. Environmental Protection Agency (EPA) and California Air Resources Board (CARB). The launch date for the new engines will be January 2015.

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/.
