Atmospheric conditions and engine configuration affect the rated output of a TNV engine. TNV engines are
tested using the methods established by the Society of Automotive Engineers (SAE) J1349 and International
Organization for Standardization (ISO) 3046/1. These standards state that engine output (net power rating)
should be determined under the following atmospheric conditions (called the standard conditions). If the
operating environment for your application differs from these standard conditions see Correcting Observed
Power
