Superflow SF880 AWD - all-wheel dynamometer with up to 1500 hp and Vmax. 320 km / h
TÜV & DMSB certified
The optimization of a combustion engine in terms of performance, torque characteristics, fuel consumption or emission requires an exact measurement on each stage of development.
The accuracy of the measurement, and especially its reproducibility have top priority, which in turn requires a high effort in measurement.
In order to be able to provide you the most advanced quality in this field as well, we operate with the currently most modern dynamometer with integrated powering of the passive axle.
The increased diameter of the individual crown rolls on this dyno allows a larger contact surface with the driven wheels, and thus low slip rates. The powering of the role for the passive (non-driven) axis is required because the electronic management systems of today's modern vehicles (vehicles in which the ESP can not be switched off) detect different speeds of the individual wheels. When greater speed differences occur, a correct power measurement is usually no longer possible because the engine usually changes to the engine emergency program in such cases.
This problem can be avoided with our high-performance dyno.
Although air pressure, intake temperature and humidity are permanently recorded and are taken into account as correction factors in the measurement result, climatic conditions as constant as possible in the measuring cell (the dyno) are of crucial importance for the quality of the measurement. The determination of the room volume with flow analyzes, ventilation and air vents, as well as the design and performance of the associated blowers therefore required a significant planning and expense.
In addition to commissioning the dynamometer, an air blower with a volume of up to 60,000 cubic metre fresh air capacity was installed, as well as an exhaust fan with 45.000 cubic metre
The KOMO-Tec performance center enables the exact measurement and recording of the following key figures:
- Power
- torque
- fuel consumption
- fuel / air mixture (lambda value)
- ignition timing
- Phasing of the camshafts
- OBD data
- intake
- Air speed in the area of the intake opening
- Water and engine oil temperature
- Oil pressure
- exhaust gas temperature
- static pressure of the exhaust system
