Deceleration Control System - Federal: Description

The Deceleration Control system is designed to maintain a balanced air/fuel mixture during deceleration. Upon initial deceleration, rapid closing of throttle plates can cause overly rich fuel mixture.

This system consists of an anti-afterburn valve, and throttle positioner system. The throttle positioner system consists of servo diaphragm, engine speed switch and 3-way solenoid valve.
