BD Diesel E-PAS Electronic Positive Air

The BD Diesel E-PAS Electronic Positive Air Shutdown (also called a positive air shut-off or emergency engine shutdown) helps protect your diesel engine from runaway. Runaway is rare. It happens when outside hydrocarbons, such as oil from a failed turbo seal, are drawn into the intake and the engine overspeeds. The E-PAS cuts off the intake air supply so the engine shuts down safely.

Key Features:

• Electronic emergency shutdown: Uses the engine's existing electronic throttle body or intake air control valve to close off airflow during an overspeed event.
• Engine-specific kit: Each kit is built for its own engine application.
• Factory-style connections: Uses factory connectors and sensors, with a pre-made wiring harness for plug-in installation.
• Simple installation: Needs only basic shop tools. It saves labor compared with mechanical butterfly-valve systems.
• Automatic reset: The system resets itself after a shutdown.
• Removable: Can be taken out if the vehicle needs to go back to its original configuration, such as a lease return.
• Window decal: Shows that an E-PAS system is installed.

BD Diesel designed the E-PAS as an engine-protection safeguard for light-duty and heavy-duty diesel applications. It is similar to carrying a fire extinguisher: you hope not to need it, but it is there if you do.
