BD Diesel E-PAS Emergency Engine Shutdown - Dodge 2010-2014 6.7L

When you're working in industries like mining, oil refining, forestry, or mobile welding, having an emergency engine shutdown system isn't just a good idea, it's often a requirement. The most effective way to stop a diesel engine in an emergency is to cut off its air supply, preventing ignition. BD Diesel's Electronic Positive Air Shutdown (E-PAS) system does just that. It uses an inline butterfly valve in the air intake that, when activated by a heavy-duty solenoid, closes off airflow and shuts down the engine within seconds.

This E-PAS unit is designed to control the electronic throttle body found on many late-model diesel engines, closing it to halt air intake during critical situations. Unlike older mechanical systems, the E-PAS can save you up to 3 hours of installation time thanks to its factory plug-in connectors and premade wiring harnesses. The butterfly valve itself is a compact design, featuring aluminum and stainless steel components with weatherproof electrical connectors to resist corrosion. Installation is straightforward, with no welding needed for hose retention thanks to innovative bead boot locks, and it can typically be completed in under 1.5 hours. It also automatically resets after shutdown and can be easily removed if needed, for example, for truck lease returns. It's a smart way to prepare for rare but potentially catastrophic events like diesel engine runaway, where external hydrocarbons can cause the engine to overspeed.

This system is designed to shut down the engine safely if it overspeeds, and it automatically resets itself after shutdown. It's also designed not to set ECM trouble codes, which is a notable benefit. While it's always best to have a system like this ready, it's even better when it installs easily and integrates cleanly with your truck's existing systems.
