As connectivity and eventually autonomous driving become more common, the auto industry may evolve to focus more on car sharing and gaining revenue from connected services. That will require changes in human machine interfaces and business models, according to panelists at SAE World Congress.
Kohler Engines has launched the KDI 3404, a 3.4-L engine in a compact footprint with a power density of 30 kW/L that reaches 100 kW (134 hp) and features an innovative Stage V ready aftertreatment system.
Metal laser melting has made a successful leap from rapid prototyping to an approved manufacturing technology, and the method is increasingly becoming an option for companies in high-tech industries, according to Toolcraft. And now the German manufacturer has teamed with Airbus APWorks to offer another option for additive manufacturing—the Airbus subsidiary’s Scalmalloy high-performance aluminum powder.
The company has put its first complete touch display with haptic feedback into demonstrator vehicles as a prelude to production. The unit is a touch-sensitive 8-in flat screen with an integrated haptic actuator system.
At this year’s Intermat, Dieter Freisler, Regional President, Wacker Neuson, emphasized that the company plans in the future to “always have double digit growth,” and that “technology development will be the basis of our growth."
Automatic transmissions with a synchronized mesh mechanism are becoming more commonplace in commercial vehicles, but there is a strong need to increase the wear resistance of sleeves and dog gears, which are subject to impact loads at high surface pressures. Hino Motors engineers achieved a 45% reduction in wear in actual parts with B, Ti-Nb added to steel.
The WI system is in pilot development with a Bosch customer. Test results to date show a reduction of fuel consumption at high loads and low rpm (up to 4% improvement on the NEDC cycle); reduction or avoidance of fuel enrichment and lower exhaust-gas temperatures at high loads and high rpm, and improved torque.
Additive manufacturing is making significant headway in aerospace production programs, as evidenced by recent announcements that Airbus and rocket manufacturer United Launch Alliance both are—or soon will be—flying aircraft that incorporate 3D-printed parts enabled by Stratasys.
A second coolant loop in a Fiat Grande Punto prototype provides liquid cooling of the A/C condenser and turbo intercooler, with potential for including air coolers for engine and transmission oil, power steering fluid and other heat exchangers. Engineers measured a 5% improvement in fuel economy during A/C-on operation during NEDC testing.
