The project will create a prototype test bed that will enable transient tests for the specified vehicle engine categories, including the NRTC test. The test bed for the optimisation of internal combustion engines is aimed at the area of machinery and equipment manufacturing. The project solution includes the technical and technological aspects of a new facility for performing and verifying optimisation activities on diesel engines. The aim is to achieve the prerequisites for obtaining ECE non-stationary test approvals for road vehicles, tractors and non-road machinery quickly and efficiently.
