Architectural and Engineering Design Standards

(avery) #1
Cooling shall be provided by a remotely installed radiator unit of the vertical discharge
style.

d. Lubrication System


A pressure type lubricating system with gear type oil pump and a full flow filter shall
be fitted to the engine.

e. Filters


Replacement elements are required.

1) Fuel Oil Systems – The system shall have a filter before the fuel injection pumps.
This filter shall be of ample capacity to prevent passage of all particles of 10
micron size or larger.

2) Lubricating Oil System – this system should have full flow filters of sufficient
capacity.

f. Intake and Exhaust System


Air is to be induced to the engine manifold through an air cleaner with dry-type
elements.

The engine exhaust line shall be fitted with expansion bellows and a critical type
silencer to give efficient silencing with maximum tolerable back pressure. The
exhaust system shall be comprised of a side entry critical silencing muffler, 12 feet of
horizontally routed exhaust piping with a “tee” fitting extending up and down, 20 feet
of vertically routed exhaust pipe, 2 - 90° elbows back to back, 20 feet of horizontally
routed exhaust pipe, a 45° fitting extending into a vertical exhaust pipe 60 feet long, 1


  • 90° elbow turning out, 12 inch stub cut off at 45° angle with a stainless steel bird
    screen to close off exhaust pipe.


The vendor shall submit with his quotation the size of the muffler and exhaust pipe
required to keep back pressure within the operating limits of the set being offered.

g. Governing System


The engine shall run steadily at any load within its rating at its rated speed, and the
changes in speed at a steady load shall not exceed 0.5% when all transients have
decayed.

The maximum speed variation upon applying a 50%, 0.8 power factor load change
shall not exceed 5%.

The governor shall have provisions for adjustment of speed. The governor actuator
shall be of the electronic type, as manufactured by Woodward or Barber Colman, used
as the governor speed control mechanism.
