Valtra: T133 biogas tractor has six-cylinder SCR engine

Valtra’s 150hp T133 Dual Fuel is the first tractor to combine the use of biogas with clean SCR technology.
The new tractor is a continuation of Valtra’s biogas project; the first test tractor – a four-cylinder N111 HiTech – was unveiled in summer 2010 and proved such a success in testing that Valtra decided to further develop the technology and adapt it for use in other tractor models.
The T133 Dual Fuel runs on both biogas and diesel. In biogas mode, approximately 83 per cent of power is produced by biogas and 17 per cent by diesel or biodiesel. A small amount of diesel is required to ignite the biogas in the cylinders. In diesel mode, the engine operates like a traditional diesel engine. Natural gas for vehicles can also be used as a fuel. The dual-fuel engine is not only more flexible than engines powered by gas alone, it’s also significantly more efficient.
The T133 Dual Fuel features an SCR system that sprays AdBlue into the exhaust gases, reducing emissions to the level required by the latest Stage IIIB standard. As a pioneer in the use of biofuels, Valtra is developing combined dual-fuel and SCR technologies to comply with even stricter standards in the future.

Valtra’s T133 and N111 biogas tractors are similar to standard tractors in terms of characteristics, equipment and performance. The fuel cost of biogas tractors is approximately 10-40 per cent lower than that of standard tractors. When driven on biodiesel and biogas, Valtra Dual Fuel tractors are powered entirely by renewable energy sources.
The storage containers for the gas are positioned in a safe location within the tractor frame. The containers can hold 170 litres of gas at 200 bars of pressure. This amount corresponds to approximately 30 litres of diesel and is sufficient for 3 to 5 hours of work. Additional storage tanks can easily be fitted to the system if needed. The tractors can also carry 165 litres of diesel and 27 litres of AdBlue, as on standard tractors.
