Porsche's all-new turbocharged flat-six engines for the 2016 911 Carrera and Carrera S are full of technology tricks for more power and fuel efficiency. Will anyone miss the unblown 3.4-L and 3.8-L units they replace?
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 challenges for the off-highway industrial engine supplier goes beyond simply meeting ever more stringent emissions regulations in Europe. Their engine designs also need to minimize total cost of ownership while delivering power and fuel efficiency in a worldwide market.
Porsche, Audi, Toyota, and Nissan each chose a different path for its hybrid-electric prototype racer at Le Mans, but one solution rose to the occasion.
The sealing specialist is currently developing two new materials that reportedly will help aircraft manufacturers save weight and production costs while exceeding fire resistance and fireproof requirements for the engine application.
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.
Tough Class A Ultra Lite from Continental Structural Plastics is a 1.2 specific-gravity sheet molding composite formulation that provides engineers the ability to design with a lower specific-gravity material without sacrificing mechanical properties, surface qualities, and adhesion requirements.
BELLOFOAM closed-cell silicone sponge sheeting from Bellofram Silicones is designed to support a variety of industrial, manufacturing, gasketing, insulation, sealing, and padding requirements in automotive, aerospace, factory floor, and industrial environments.
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."
With an electromagnetic clutch located between the drive pulley and supercharger rotors, the blower can be disengaged during idle, light throttle, and cruising situations.
Can a supercharger with a mechanical variable speed drive give a downsized engine the performance “feel” of a larger-displacement, naturally-aspirated unit without sacrificing efficiency? A joint U.K. research project aims to find out.
