Engine test conditions. 2.1.1. The absolute temperature (Ta) of the engine air at the inlet to the engine expressed in Xxxxxx, and the dry atmospheric pressure (ps), expressed in kPa shall be measured and the parameter fa shall be determined according to the following provisions. In multi-cylinder engines having distinct groups of intake manifolds, for example, in a "V" engine configuration, the average temperature of the distinct groups shall be taken.
Engine test conditions. 2.2.1. The absolute temperature Ta of the engine intake air expressed in Xxxxxx, and the dry atmospheric pressure ps, expressed in kPa, shall be measured, and the parameter fa shall be determined according to the following provisions: Naturally aspirated and mechanically supercharged engines: ⎛ T ⎞0.7 f a = ⎜ p ⎟ x ⎜ ⎟ 298 ⎝ s ⎠ ⎝ ⎠ Turbocharged engine with or without cooling of the intake air: ⎛ 99 ⎞0.7 ⎛ T ⎞1.5 f a = ⎜ ⎟ p x ⎜ 298 ⎟
