Performance Benefits of Jacobs ADT

Eliminates engine-shutdown-induced cabin vibration Faster transition from eMotor to ICE in hybrid vehicles Improves driver satisfaction Increases engine cranking speed for easier start-up Improves cold start Lowers cranking torque & current draw Reduces starter system wear Reduces crank and bearing starting loads and wear Simple, cost-effective design Compliments start-stop fuel savings strategies Increases driver willingness to use optional start-stop

How ADT Works

During Start-up When the engine is turned on, the ECU automatically activates the device to keep the engine valve open. This keeps the engine in a decompressed state, which decreases the cranking torque and allows the starter to spin the engine at a higher speed.

During Shutdown Upon shutdown, the ECU activates the device to keep the engine valve open. By keeping the valve open, the engine is able to coast to a smooth shutdown without causing the cab to shake.

Cold Start Up In cold temperatures when an inlet air heater is used, the engine can be turned over while decompressed. This allows pre-warming the inlet air and engine cylinders without the engine load from compression.
