Details

The 4x4 Dynamometer is very popular due to the versability ....The weight of the rollers is calculated to accurately simulate road conditions and therefore lends itself to an ideal tuning tool for performance related dyno tuning. Full load remapping can be done on the inertia dynamometer which has the advantage that it does a complete power and torque curve in less than 30 seconds. This reduces the dynamometer time dramatically and subsequently engine wear. Furthermore the engine does not overheat as easily as with the constant speed or loading dynamometers. A loading facility (eddy current brake) can be added to the standard inertia dynamometer which enables the user to either put a fixed load on the brake or to hold the vehicle at a certain rpm, as well as perform a controlled sweep test (ramp test), where the speed is gradually increased while the power and sensor readings are recorded. This is especially handy when a problem is encountered at a specific rpm or load condition. Where applicable, the loading facility can also be used to do engine mapping. A road simulation can also be done which accounts for: vehicle weight, acceleration, wind resistance and road inclination. Up to 64 sensors (temperature, pressure, etc) can be added to this system, which may help the serious tuner in assessing problems. An integrated Air/Fuel ratio meter records real-time values that can be displayed graphically with the performance figures. This can be done for Loading and Inertia tests The Air/Fuel ratio meter can be used as a stand-alone unit that can be used on the road or racing track. The knurled rollers ensure good traction and limits unnecessary heat buildup in the tyres.
