Goals and idea

Due to extensive and high-quality equipment, it is possible to operate combustion engines in the power range up to 330kW at different loads and speeds and to carry out thermodynamic analyses or highly accurate fuel consumption measurements and to determine exhaust emissions. In addition, the laboratory has an all-wheel drive roller test bench, which can be used to analyse the operating behaviour of complete vehicles with different drive systems (combustion engine, electric motor, hybrid). For vehicle manufacturers, the chassis dynamometer is an indispensable development tool, the benefits and possible applications of which every vehicle engineer should have become familiar with during his training.
