Nonox converted an conventional gas-engine to an EOCV operated engine, in order to reach clean agricultural transport. In this project the engine is built into a tractor, in order to show the advantages. The tractor will run on natural (bio) gas. Nonox is offcourse involved in the conversion of the engine to EOCV load-control, but also in the engineering work necessary in order to make the vehicle communicate with the engine on a proper way. This was needed, because the engine and vehicle are from a different brand. Nonox also did the engine mapping, in order to reach good efficiency and drivability results.
