Deceleration Control System: 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 (air by-pass valve on California models) and throttle positioner system. The throttle positioner system consists of servo diaphragm, engine speed switch and 3-way solenoid valve. The California M/T model also uses a throttle dashpot in addition to the throttle positioner.
