Bendix® PBS® Engine Air Injection

This video compares the performance of a commercial vehicle on an incline with a weighted trailer equipped with the Bendix® PBS® engine air injection system versus a non-PBS-equipped commercial vehicle. The Bendix PBS engine air injection system is the first air management system of its kind to simultaneously improve fuel economy and vehicle acceleration, while reducing engine emissions. The system is placed between the turbocharger compressor and the engine air intake where it monitors the Controller Area Network (CAN) for specific signals. Once the conditions for activation are met, the system injects compressed air from an air reservoir into the engine manifold, delivering the desired amount of air that the diesel combustion processes require. When a driver presses the accelerator pedal in a vehicle without PBS air injection, there is a delay in vehicle acceleration response often referred to as turbo-lag. The Bendix PBS system overcomes turbo-lag by injecting air into the engine air intake until the tubo-charger can supply the air required to meet the driver demand for vehicle acceleration.
