4.3 Forced Air

With the forced-air system, cooling air is drawn in

through the front of the engine, circulated around finned

areas of the cylinder block and head, then ejected

toward the rear or generator end of the set. This system

is best suited to wide-open, well-ventilated areas. It is

not recommended for confined areas unless intake

and/or exhaust fans are used to achieve the required air

circulation. See Figure 4-5.
