Description & Operation

The Heated Air Intake system is designed to maintain the air temperature entering the carburetor at a constant temperature. This is done by blending heated (manifold) and ambient (outside) air.

A temperature-sensitive bi-metal valve (temperature sensor) controls a flap valve which regulates the amount of air entering from the hot and cold air inlets, thereby maintaining the correct air temperature under all operating conditions.
