Gucbir D-300 - The Height from Sea-Level; Fuel System; Exhaust and the Muffler

6.7 The Height from Sea-level
The pressure of fuel pumps of the engines are adjusted in the factories equal to 760mm Hg. The altude
aects the performance of the generators. The eect of the altude is less in turbo-engines compared to
natural intake engines.
6.8 Fuel System
For proper running, there must be a steady and proper ow in the fuel system. Thus, the lters must be
replaced in due me and the ex pipes must be controlled duly.
A breakage or smash in the hosepipes that transfers fuel to the pump leads the engine to lose performance
or to stop.
If the fuel tank is planted in a high place, it is beer to put a valve for the demounng in case of a fault.
On the other hand, if the fuel temperature is higher than 35 Celsius, it causes the performance to de-
crease. Thus, keep the fuel hosepipes away from the radiator, exhaust, sunlight…etc.
Place the taps, which are used for drainage from tank during the group assembly, in a reachable and
demountable point.
6.9 Exhaust and the Muer:
It is important for the group generator room to be insulated in terms of temperature control. But, a
thermal insulaon solely has a negave eect on sound insulaon.
On exhaust lines the place of the muer has an important eect in terms of sound insulaon. In order to
get the best result for sound insulaon, the length of the pipe aer the muer must be between 0.8 and
1.5m.
It is benecial to place the muer close to the engine exhaust exit, if it is dicult to place it close to the
pipe exit.
