Composites replacing steel applications
ATZautotechnology - Tập 2 - Trang 40-41 - 2002
Exhibitors at the annual JEC composite show in Paris showed structural and Class A body panels now in production and predicted that they would gain more share from metal because their material can be formed in shapes that metal cannot duplicate.
Simulating the Effects of Fuel Injection on Combustion
ATZautotechnology - Tập 4 - Trang 42-45 - 2004
Historically, automotive design engineers have faced multiple challenges in analysing the interaction between injection and combustion. An Integrated Simulation approach can provide engine designers with a tool that allows the simultaneous analysis and design of the fuel injection and combustion processes, under steady-state and transient engine operating conditions.
Frictional Coatings in Powertrain Applications
ATZautotechnology - Tập 4 - Trang 62-65 - 2004
Load transmission in friction joints is limited by the coefficient of static friction of the respective mating materials. ESK Ceramics GmbH & Co. KG produces nickel-diamond coated foils that can increase the load transfer capability of friction joints subjected to torsional or shear loads by up to 300 %.
Honda’s current and future engine technologies
ATZautotechnology - Tập 1 - Trang 70-73 - 2001
Serious air pollution problems in major cities and global warming concerns have led to proposals to replace the internal combustion engine in vehicles. However, in order to commercialise new power units, major issues such as fuel infrastructure and cost must be resolved.
Audi R10 — First diesel heads for Le Mans
ATZautotechnology - Tập 6 - Trang 28-31 - 2006
The inventor of “TDI” will become the world’s first car manufacturer to fight for overall victory with a diesel engine in the famous Le Mans 24-hour race. The Audi R10 is powered by a 5.5-litre, twelve-cylinder biturbo TDI engine. The V12 power plant is manufactured completely from aluminium.
Behr’s new climatic wind tunnel
ATZautotechnology - Tập 1 - Trang 40-43 - 2001
Behr GmbH & Co’s new climatic wind tunnel for testing vehicles ranging from small cars through to the largest trucks has been in operation since January 2001. Features of the system include extremely precise and realistic environmental simulation, high-quality air flow and low background noise, which makes it possible to test the interior acoustics of a vehicle.
An adaptive dynamic model for the virtual engine
ATZautotechnology - Tập 1 - Trang 74-76 - 2001
The passenger car engine development process requires CAE models that deliver results for the concept phase at a very early stage and which can be further detailed on the same program platform as the development process progresses. An engine dynamics model that meets these requirements is described here.
Molded silicone rubber automotive parts
ATZautotechnology - Tập 1 - Trang 32-35 - 2001
Though not always immediately visible, siliconerubber parts have become indispensable in modern automotive engineering. Thanks to their versatile properties, they are to be found in the engine compartment, in the drive system, in electrical and electronic systems, around the body and increasingly in the interior, in fact wherever sealing or covering functions are needed.
Development Tendencies for Lightweight Design of the Future
ATZautotechnology - Tập 8 - Trang 18-22 - 2008
Audi started its development in automotive car bodies made out of 100 % aluminium back in the early 1980’s. The expected result of a car body structure made out of aluminium was an extreme saving in weight. The secondary effects are an increase in linear and non-linear vehicle dynamics and lower fuel consumption and emissions while presenting similar and even better results in body-stiffness, -rig......
A New Development in Automotive Wind Tunnels
ATZautotechnology - Tập 5 - Trang 50-52 - 2005
While automotive companies are needing better aerodynamic data, the wind tunnel industry has not done much basic research into the known limitations of the wind tunnel, until now.
