Cover Stories

Three-cylinder engines are an acoustic challenge, but if the exhaust system is well designed, they can convey a sound image appropriate to a luxury car: generally quiet and without dominating orders. ...

The trend in the development of vehicles with hybrid or electric drives confronts the automotive industry with new challenges. Electric vehicles require lighter materials than conventional ...

The expected quantities and enormous pricing pressures involved are forcing producers of carbon components to manufacture CFRP (carbon fibre reinforced plastic) on an industrial scale, for which ...

Manufacturers of transmissions are faced day-by-day with the challenge of having to develop more efficient transmission components to achieve ever higher torques and greater facility in gear ...

Maximising the uniformity of the catalyst flow and simultaneously minimising the backpressure is an essential goal of exhaust system development, which is often complicated by restrictive underhood ...

Possible means of meeting future CO2 requirements include the application of various measures to optimise the internal combustion engine and transmission or the electrification of the powertrain. ...

In a flow sharing system, the highest load pressure of the hydraulic consumers is sensed by a variable pump. This is controlled in such a way that a pump pressure that is higher by a certain ...

For the development of vehicles with alternative drive systems, it is more important than ever to know the potential customers, so that the respective vehicle drive system can be positioned on the ...

Vehicles have been able to drive electric for more than 100 years. However, in order for electric cars to be competitive,both on an economic and technical level, they will require specifically ...

Downsizing in combination with turbocharging enables sustainable CO2 emission reduction. In order to mitigate knock at higher engine loads, the compression ratio has to be diminished with increasing ...

A new family of multi-speed transmissions from Oerlikon Graziano, based on the principles of dual clutch transmissions, provides an alternative approach to increasing the efficiency, performance and ...
