Engine Power Rating information
The gross power rating for individual gas engine models is labeled in accordance
with SAE (So-
ciety of Automo-tive
Engineers) code J 11940 (Small Engine Power & Torque Rating Procedure),
and rating performance
has been obtained and corrected in accordance
with SAE J1995 (Revision
2002-5).
Actual gross engine power will be lower and is affected by, among other things, ambi-
ent 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.
Due to manufacturing
and capacity limitations,
Briggs & Stratton
may substitute an engine of higher rated power for this Series engine.
