Thermostatic Air Cleaner: Description and Operation
Fig. 5 - Heated Air Intake System
Carburetor air temperature is controlled by the heated air intake system, Fig. 5. This system consists of a mixing valve containing a damper door
(4) and a wax pellet thermostatic switch (5). The mixing unit receives hot air from a heat shroud surrounding the exhaust manifold and cold air
from a second duct. When incoming air reaches a temperature of 59-68 F (15-20 C), the wax pellet switch expands and close-off hot air entry thus
admitting cold air. The damper is fully opened to cold air at 78.8 F (26 C).
