Engine Power Rating Information
The gross power rating labels for individual gas engine models meet or exceed SAE (Society of Automotive
Engineers) code J1940 (Small Engine Power & Torque Rating Procedure) and rating performance has been
obtained and corrected in accordance with SAE J1995 (Revision 2002-05). Actual gross engine power may be
lower and is affected by, but not limited to, ambient operating conditions and engine to engine variability. Given
both the wide array of products on which engines are placed, and the variety of environmental issues applicable
to operating the equipment, the gas engine will not develop the rated gross power when used in a given piece of
power equipment (actual “on-site” or net horsepower). This difference is due to a variety of factors including, but
not limited to, accessories (air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.), application
limitations, ambient operating conditions (temperature, humidity, altitude), and engine to engine variability.
