Interview with Pierre-Antoine RAMPON (manager of the LORRTEC company):
The engines are then equipped with numerous sensors (temperature, pressure, knock, cylinder pressure, etc.) in order to carry out tuning under optimum safety conditions.
Our SCHENCK ex “Formula 1” test bench allows us to fine-tune any type of engine with speeds up to 18,000 rpm and powers up to 1,000 hp.
The ROTOTEST test bench is comparable to a set of engine benches coupled to each drive wheel of the vehicle. Unlike a traditional (roller) test bench, it is an extremely precise measuring instrument thanks to high-resolution torque sensors measuring the force directly at the wheel hubs.
This new type of dynamometer is similar to a roller dynamometer but has much greater precision and testing flexibility. Among the main advantages, we find the absence of slippage between the wheels and the bench, the very low inertia of the system as well as a precise and independent measurement of all losses by friction.
In addition, this system does not damage the tires and adapts to all vehicles, regardless of running gear geometries.
