The Bendix Pneumatic Booster System (PBS), is an air management system aimed at improving fuel economy and acceleration while reducing emissions. Placed near the air intake manifold on the engine, the PBS monitors the controller area network for signals to activate. The PBS then injects compressed air from an auxiliary air tank into the engine manifold, delivering the desired amount of air. The system is intended to overcome turbo lag, which leads to a delay in response when a driver presses the accelerator. Bendix says two models are available, reaching about 80 percent of engine applications from 4-liter displacement to 13 liters.
