LOUISVILLE, Ky. — Continuing in its efforts to provide customers with a cost-effective and environmentally friendly air management energy system, Bendix Commercial Vehicle Systems announced here during the Mid-America Trucking show that the company had developed three optimized components.
The Bendix PBS Air Injection Booster, Bendix Electronic Air Control (EAC) Dryer and Bendix Turbo-Clutch Air Compressor all work together to maximize engine efficiency and improve emissions, according to Steve Mance, Bendix vice president and general manager for the charging business group, who noted that together all three components can equate up to 8 percent in fuel savings per commercial vehicle.
Bendix introduced its groundbreaking PBS air injection technology to the commercial vehicle industry in 2009.
Since then, the company has continued its internal validation and field testing.
Preliminary results show that fleets can save up to 3 percent per vehicle in fuel with the addition of just the PBS unit, Mance said
“The Bendix PBS engine booster is unlike any other product available on the market today,” Pence said.
The system is placed near the air intake manifold on an engine and monitors the Controller Area Network (CAN) for specific signals.
Once the conditions for activation are met, the system injects compressed air from an auxiliary air tank into the engine manifold, delivering the desired amount of air that the diesel combustion processes require.
Typically, when a driver presses down on the throttle to demand acceleration, there is a delay in engine response because of turbo lag.
This lag constitutes the time difference between acceleration demand and the maximum air delivery of the turbocharger.
The Bendix PBS system overcomes turbo lag by instantaneously injecting the desired air into the intake manifold, allowing the turbocharger to spin up to its full capacity and take over the air delivery demands.
“Bendix PBS air injection is the first air management system of its kind to improve fuel economy and reduce emissions, while also helping to increase engine performance,” Mance said. “The integration of PBS engine booster, EAC dryer, and the Turbo-Clutch Air Compressor can provide a significant ROI for our fleet customers.”
The Bendix EAC system is a compact, electronically controlled air treatment system.
The system integrates the air dryer, unloader valve, multi-circuit protection valve, and has the capability to integrate the park brake mechatronics. Its four primary functions are air quality assurance, pressure control, air distributions defined according to customer priorities, and information management. The sensors enable optimized system control, plus on-board/off-board diagnostics.
A commercial vehicle equipped with EAC technology can save up to 2 percent in fuel savings, Mance said
The pneumatically operated single-cylinder Bendix Turbo-Clutch Air Compressor works together with PBS air injection and EAC, so that the compressor disengages during the portion of the duty cycle when no air is demanded. This highly reduces power consumption from the engine and increases fuel efficiency. As a result of the reduced overall cycling, the life cycle of the compressor significantly increases and normal wear and tear is dramatically reduced.
“The total energy package from Bendix can reduce fuel consumption by up to 8 percent,” Mance said. “This is a significant savings to both the owner-operator and the fleet manager. Bendix will continue in its efforts to set a benchmark for the industry as we continue to design and engineer components that benefit our customer and the environment, while responding to changes in global regulations.”For more information, visit bendix.com.
