„normal deceleration“ | Acceleration in 3rd gear up to 2000 RPM (revolutions per minute). Two minutes of constant 2000 RPM were followed by a deceleration phase of ten seconds to 1750 RPM. The gas pedal position was unchanged during this deceleration phase to simulate the inertia of the car. 8 repetitions (8×) were performed in 16 minutes. |
---|---|
„full stop“ | Acceleration in 3rd gear up to 3000 RPM. After two minutes of constant 3000 RPM, a „full stop“ was performed with the gas pedal position unchanged until the engine stalled. The engine then had to be restarted for the next cycle. 4 and 8 repetitions (4× and 8×) were performed in 8 and 16 minutes. |
„no stop run“ | Acceleration in 3rd gear to 2'000 RPM with the speed remaining stable throughout the entire measurement cycle of 16 minutes. |
