“The development of the biogas tractor and generator demonstrates the desire of AGCO to create solutions that allow renewable natural resources to be utilized efficiently,” says Martin Richenhagen
, AGCO Chairman, President and Chief Executive Officer.
AGCO’s Valtra brand and AGCO SISU POWER, AGCO’s innovative engine division, have developed the biogas tractor and are currently testing it in Sweden. Without making any changes to the original diesel engine, 70 to 80 percent of power is generated by biogas. The dual-fuel engine functions like a diesel engine. The gas is injected with the intake air, and combustion occurs when a small amount of diesel fuel is injected into the cylinder. If biogas is not available, the engine can run completely on diesel fuel.
The Valtra N101 tractor has 110 horsepower, is equipped with a front loader, front linkage and front PTO. It is intended as an all-purpose tractor for farms, municipalities and contractors that have the possibility of refuelling with biogas while working. The biogas cylinders are situated in a safe location on the right side of the chassis, and the entire installation has been designed in accordance with EC vehicle regulations. The capacity of the biogas cylinders on the first test model is 170 litres, which under 200 bar pressure corresponds to approximately 30 litres of diesel fuel. In typical use this is sufficient for three to four hours of work.
“State-of-the-art technology has been employed in Valtra’s biogas tractor. Both the diesel and gas injection systems have their own electronically controlled common rail, which allows the ratio between the diesel and biogas to be optimized,” explains Jari Rautjärvi, Managing Director of Valtra.
The demonstration tractor was created by Valtra in collaboration with Afcon Oy, Alt-Control Oy, RAP Clean Air Systems, Turku University of Applied Sciences and Ecocat Group. Valtra's sister company AGCO SISU POWER Genpowex was also involved in the project and helped develop a dual-fuel generator that can also be seen at the Borgeby Fältdagar event. Valtra's partners in the project from the start have been Biogas Syd and Lantmannen Maskin. The tractor will undergo further testing in Skåne, while the dual-fuel engine will continue to be developed in the engine lab.
“AGCO’s innovative technology also provides environmental benefits. Our leading-edge transmission and engine technologies reduce emissions and noise while improving fuel economy. The new concept tractor is a great example to show how biodegradable fuels and biodiesel fuels can be put to work in real-world applications,” states Mr. Richenhagen.
AGCO is committed to supplying progressive farmers with high-tech solutions and to develop environmentally friendly technologies. AGCO has only recently been selected by the U.S. Department of Energy for a grant for the efficient collection and transportation of biomass to biofuel production plants. In 2009, AGCO was the first agricultural company to introduce the industry-leading SCR emissions treatment in its products.
