Engine Power Rating information
The gross power rating for individual gas engine models is labeled in accordance
with 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). Torque values are derived at 3060 RPM; horsepower
values are derived at 3600 RPM.
Actual gross engine power will be lower and is affected by, among other things, ambient operat-
ing 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 equip-
ment (actual "on-site"
or net power). This difference
is due to a variety of factors including,
but not
limited to, accessories
(air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.), ap-
plication 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.
