alternator windings and open connections
Common exhaust system for multiple engines
G.12 Common exhaust system for multiple sets is not recommended due to condensation, excessive suction pressure,
entry of exhaust gases in non working engine, increased back pressure and lack of fail safe system availability.
However exhaust of two banks of V-engines can be connected, after silencer. Ensure that area of common pipe
is greater than sum of the areas of individual pipes.
G.13 Exhaust of engines can be directly connected to chimney at different levels as shown.

H. Fuel System
H.1 Fuel supply and return line restriction for PT fuel system
is max. 100 mm Hg.
Higher restriction leads to :
- Lower power
- Late stopping
- Engine die down
H.2 Typically fuel tank should be placed on the level as
that of engine i.e. floor mounted. Locate fuel tank such
that fuel outlet point (at bottom of fuel tank) is maximum
1.8 m (6 feet) below the fuel pump inlet or for top mounted
fuel tank, top side of fuel tank is max 1.5 m (5 feet)
above fuel return line. In case of Top Mounted tanks
non return valves are must in fuel supply and return
lines of specified value. Please contact OEMs /
Cummins for necessary details.
For AMF critical start engines, minimum 0.45 m (18”)
of gravity fuel feed needs to be provided to fuel pump
at inlet connection.
