EMISSIONS - RELATED INSTALLATION INSTRUCTIONS
3/5
Although there is no problem for installing expansion joints or flexible exhaust pipes, the following should be
taken into consideration:
-
The expansion joints are basically designed to make good any longitudinal extension of the exhaust pipes.
-
To prevent exhaust pipes from moving crosswise, the pipes should be guided and attached to the engine
room structure in such a way that their longitudinal movement only is permitted to avoid damage to the
expansion joints.
-
The expansion joints have one single assembly position in accordance with the direction of the exhaust gas.
-
The number of joints to be installed is determined by the length and layout of the exhaust pipeline.
Figures 2 and 3 show the admissible axial shift and cross travel as well as the direction of exhaust gas
escape for standard
Kohler flexible pipes.
The dimensions of the engine exhaust connections for V engines are given in IT-G-A-40-002e. In line engines
don’t require special connections.

INSTRUCTIONS FOR INSTALLATION OF THE FUEL PIPE
In order to control emissions efficiently the elements and dimensions of the pipes and components must be in
such way to comply the gas specifications for the fuel supply described in IC-G-D-30-007e (TECJET 50+ gas
injector) or IC-G-D-30-012e (TECJET 110 gas injector).
The gas ramp must include, at least, the following elements in the same order: manual shutoff valve, filter,
pressure regulator (if required) and valve train.
The fuel gas must comply with the specifications described in IC-G-D-30-002e (Gas Natural) or IC-G-D-30-003e
(Biogas) or IC-G-D-00-04e (syngas). Other gas qualities or failures in the specifications meeting can affect
emissions levels, being out of the emissions levels according to the 40 CFR 60 subpart JJJJ
standards. Kohler is not responsible for the emission level compliance in these situations
Check leakages before engine first start.
