EMISSIONS - RELATED INSTALLATION INSTRUCTIONS
5/5
-
The fitting of the air intake duct should be studied by the installer and should eliminate all the abnormal
forces due to the sheer weight of the air intake duct and all the vibrations which could be produced, as both
these factors could result in problems for the correct functioning of the engine.
-
The air intake duct connection to engine should be made by means of a flexible rubber hose.
-
Fit a drain cock at the lowest point of the air intake duct. This point is generally as near as possible to the
turbochargers. It is important and necessary that, if the air intake duct were over hot parts it would be well
isolated.
(See fig.4)

-
In any case, the air temperature for combustion should not exceed in general 25°C (77ºF) at the filter entry
point, otherwise it will be necessary to reduce the engine power.

ENGINE INSTRUMENTATION
The instrumentation is defined in IO-G-M-60-002e. In this Product Information sheet you can find the engine
running parameters that must be monitored, the limit values for this parameters and the alarm logic operation.
7.
IN USE TESTING
The U.S. EPA certification regulations for LSI engines require the engine manufacturer (Dresser
-Rand
A
Siemens Business) to notify the equipment manufacturer that sampling of exhaust emissions must be possible
after engines are installed in equipment and placed in service. If this cannot be done by simply adding a 20-
centimeter extension to the exhaust pipe, you, as the equipment manufacturer, must demonstrate to Dresser-
Rand A Siemens Business how to sample exhaust emissions in a way that prevents diluting the exhaust sample
with ambient air.
8.
ADJUST FUEL AIR RATIO
The carburetion control systems are designed to maintain the emissions level during all typical operating
conditions. Under extreme or unusual operating conditions (gas quality, gas pollutant, dusty ambient, extreme
season temperatures) carburetion settings need to be confirmed and potentially adjusted. To “check / adjust
fuel air ratio” the exhaust emissions and actual A/F ratios are confirmed. If adjustments are necessary, they
are performed using Kohler proprietary software interface and only performed by Kohler authorized
service technicians.
