  "heading": "Generation of NRTC & LSI-NRTC speed and load for each test point (denormalization)",
  "text": "This point shall be used to generate the corresponding engine speeds and loads over which the engine shall be operated during NRTC or LSI-NRTC tests. Appendix 3 of Annex XVII defines applicable test cycles in a normalized format. A normalized test cycle consists of a sequence of paired values for speed and torque %.\nNormalized values of speed and torque shall be transformed using the following conventions:\n(a) The normalized speed shall be transformed into a sequence of reference speeds, n ref, in accordance with point 7.7.2.2;\n(b) The normalized torque is expressed as a percentage of the mapped torque from the curve generated according to point 7.6.2 at the corresponding reference speed. These normalized values shall be transformed into a sequence of reference torques, T ref, according to point 7.7.2.3;\n(c) The reference speed and reference torque values expressed in coherent units are multiplied to calculate the reference power values.",
