engine. The filter shall be capable of removing particles 10 mm 3/8 inch
and larger.
2.11.2.2
Air Driven Motors or Cylinder Injection
Either type of air starting system, air motors or direct injection, is
acceptable. If an air motor starting system is used, the cranking motors
shall be complete with a solenoid valve, strainer, and lubricator. If
cylinder injection starting is used it shall be accomplished by admitting
compressed air into two or more engine cylinders through a timing valve, or
through a distributor into a sufficient number of cylinders to ensure
successful starting regardless of piston positions.

Starting Aids
**************************************************************************
NOTE: Jacket coolant and/or lube-oil heaters are
normally provided for most applications to aid
starting. Either injection or glow plugs may also
be required for combustion air temperatures
significantly below 0 degree C (32 degree F).
Consult manufacturers for availability and need in
the application size range.
**************************************************************************
2.11.3.1
Jacket-Coolant Heaters
A thermostatically controlled electric heater shall be mounted in the
engine coolant jacketing to automatically maintain the coolant within 10
deg of the control temperature. The heater shall operate independently of
engine operation so that starting times are minimized, condensation is
controlled, and the system ensures dependable, cold weather starts. Power
supply for the heaters will be [_____] volts AC.
2.11.3.2
[Glow Plugs
**************************************************************************
NOTE: Delete this paragraph if natural gas fueled
spark ignited engines are specified.
**************************************************************************
Glow plugs shall be designed to provide sufficient heat for fuel combustion
within the cylinders to guarantee starting at an ambient temperature of -23
degree C -20 degree F.]
2.11.3.3
[Lube Oil Heaters
A thermostatically controlled electric heater shall be mounted in the
engine lube oil storage tank to automatically maintain the lube oil within
10 deg of the control temperature. The heater shall operate independently
of engine operation so that starting times are minimized and the system
ensures dependable cold weather starts. Heaters shall be selected so that
heater skin temperatures do not exceed 150 deg C 300 deg F and have maximum
heat densities of 0.02 W/mm square 13 W/in. square. Power supply for the
heaters will be [_____] volts AC.]
