A new package of technologies from Bendix Commercial Vehicle Systems promises to improve engine performance, regardless of type or OEM. The package consists of Bendix’s PBS Air Injection Booster, Electronic Air Control (EAC) Dryer, and Turbo-Clutch Air Compressor.
Together, the systems enhance vehicle performance, reduce fuel consumption, and improve emissions, Bendix said, by optimizing the performance of all engine types equipped with turbochargers, including those using selective catalytic reduction and advanced exhaust gas recirculation.

“At Bendix, we’re driven to deliver a total energy management system that brings maximum benefit to all of our owner-operator and fleet partners,” said Steve Mance, vp & gm for the Charging business group. “By integrating the PBS engine booster, the EAC dryer, and the Turbo-Clutch Air Compressor, our customers can realize a significant ROI.”
The PBS air injection technology, first introduced last year, communicates with the engine’s controller area network (CAN) to inject precise amounts of air from an auxiliary tank directly into the air intake system to push the turbocharger up to its full capacity and take over the engine’s air boosting demands. This virtually eliminates turbo lag, allowing the engine to reach optimum speed quicker and also saving up to 3% in fuel, Bendix said.

A side benefit of the system is less diesel particulate matter and nitrogen oxides produced.
“Our solution is designed specifically to help all vehicle manufacturers reduce emissions, while improving engine performance and energy efficiency, regardless of the type of engine they produce and the emission-reducing technology they utilize,” said Mark McCollough, Bendix product line director for air treatment.
The EAC system is a compact, electronically controlled air treatment system that integrates the air dryer, unloader valve, multi-circuit protection valve, and optionally the park brake mechatronics. Sensors help it in its four primary functions: air quality assurance, pressure control, air distributions defined according to customer priorities, and information management.
The pneumatically operated, single-cylinder Turbo-Clutch Air Compressor works in tandem with PBS air injection and EAC, so the compressor disengages during the portion of the duty cycle when no air is demanded.
“Bendix EAC further complements PBS air injection and the Turbo-Clutch Air Compressor by building or purging air at the most energy-efficient times, such as when there is low engine load as occurs during deceleration,” McCollough said. “Vehicles can reach 8% fuel savings when the three air management technologies are in place, working together.”
