Deceleration Control System: Description

The Slow Fuel Cut system is used to seal the primary slow fuel passage of the carburetor to prevent "dieseling" and overheating of exhaust system. It is part of the Computerized Engine Control system.

Components of the system include the slow fuel cut solenoid valve, neutral switch, clutch switch (manual transmission), idle switch and necessary electrical connections.

Vehicles also incorporate a Coasting Richer System in the Slow Fuel Cut System. The Coasting Richer System opens the carburetor secondary stage fuel line during deceleration.
