Alcohol Evaporation System. (Illus. 4-22).
When the Compressor is in the compression cycle, a partial vacuum is present at the Compressor Intake. Tubing from
the Alcohol Evaporator is connected to the Compressor Intake, therefore a partial' vacuum is also created above the
alcohol in the Alcohol Reservoir. Air (atmospheric pressure or greater depending on type of installation) enter the
Alcohol Evaporator, passes through the tube which is immersed in the alcohol. The passing of air through the alcohol
allows the alcohol to bubble, and the vapor formed by the bubbling is induced into the Compressor intake and into the air
brake system.
Quick Start System
The Quick Start System has an atomizer, valve assembly and ether bottle. The Quick Start System is usually used
during cold weather operations to facilitate engine starting. To operate the system, the starter switch must be in the start
position before the quick start button is depressed. With the starter switch in the start position, and button depressed, the
valve assembly is actuated open.
Ether flows from the bottle, and is squirted into the intake manifold.
