commercial carrier journal | april 2017 69 Navistar's 12.4-liter engine Navistar's International 12.4-liter A26 inline six-cylinder engine weighs 2,299 pounds – 55 pounds lighter than the N13 engine it will replace in the company's order book at the end of the year. The engine, which is 2017 greenhouse gas certification-pending, provides up to 475 horsepower and 1,750 lb.-ft. of torque and is available for order on Internation - al LT Series long-haul tractors and RH Series regional-haul trucks. The lightweight design includes a compacted graphite iron crankcase, a shot-peened alumi - num flywheel housing, composite valve covers and a hollow assembled camshaft that features tool-grade steel lobes for added durability. A variable geometry turbocharger, which uses a titanium compressor wheel with a simplified single-stage design, simplifies the engine's air and cooling system and also boosts engine braking power by up to 67 percent. A high-pressure fuel system helps boost fuel economy by upwards of 5 percent versus the N13. The cylinder head's port flow geometry is optimized to reduce air restriction and help the engine breathe more consistently from cyl - inder to cylinder to help increase fuel efficiency. A six-blade radiator fan and a sculpted crankcase and oil pan both help reduce noise. The pistons are engineered with a low-friction skirt coating and advanced piston ring geometry to reduce parasitic losses while also helping to enhance fuel economy. An oil cooler thermostat bypass allows oil to bypass the oil cooler in colder weather, which also helps improve fuel economy. Larger piston pins, connecting rods and bushings help optimize load distribution, and smaller piston cooling jets increase oil pressure to improve lubrica - tion, which helps increase oil change intervals up to 70,000 miles. A laser-welded stainless-steel single-stage exhaust gas recircu- lation cooler is designed to deliver reliability and performance in a compact easy-to-service package. Navistar International, www.navistar.com, 331-332-5000 Tire management platform Dana Inc. unveiled Rhombus TireAnalytics, a cloud-based tire management platform designed to enable truck owners and fleet maintenance managers to identify best practices for tire maintenance and optimize tire lifecycle management. The plat - form can help provide insights into the condition of tractor and trailer tires, help identify and analyze tire wear trends, predict maintenance issues that can be addressed preemp - tively to minimize truck downtime and establish optimal timeframes for scheduled replacement. For larger fleets, it also can help implement custom standardized tire inspection and maintenance practices across terminals. The system integrates portable communi - cations and computing platforms, advanced data collection and analysis, information sharing and dashboard technologies through a cloud-based solution that can be implemented with existing mobile, tablet and desktop devices. Dana Inc., www.dana.com, 419-887-3550 Self-deploying trailer tail Wabco's OptiFlow AutoTail aerodynamic trailer fairing is en- gineered for automatic deployment and retraction based on driving speed as determined by sensors linked to the compa- ny's Trailer Anti-Lock Braking System. The device is designed to deploy automatically at vehicle speeds of 45 mph to ensure it is used to help maximize aerodynamic fuel savings at high - er speeds and to retract automatically at 10 mph. It is made from automotive-grade thermoplastic, a lightweight, durable and long-lasting material that resists wear from weather and vibration. The injection-molded panels have a curved shape and smooth surface that help reduce air resistance. Wabco, www.wabco-optiflow.com, 248-276-1970
