  • Stall point:

    • Stall point at 70 % nominal engine speed.

    • Engine torque in stall point at 80 % maximum engine torque.

    • Engine/Pump reference torque in stall point:

      TP1000v0=Tmax×0,80×1000rpm0,70×nn2math
  • Intermediate point:

    • Intermediate speed ratio vm = 0,6 * vs

    • Engine/pump reference torque in intermediate point at 80 % of reference torque in stall point:

      TP1000vm=0,8×TP1000v0math
  • Coupling point:

    • Coupling point at 90 % overrun conditions: vc = 0,90 * vs

    • Engine/pump reference torque in clutch point at 50 % of reference torque in stall point:

      TP1000vc=0,5×TP1000v0math
  • Overrun point:

    • Reference torque at overrun conditions = vs:

      TP1000vs=0math
