Vienna Motor Symposium 2015
1,000 experts from all over the world came to the 36th International Vienna Engine Symposium and presented the latest concepts for engines with lower consumption and emissions in the Hofburg.

In addition to 48-volt hybridization, other interesting strategies were presented to reduce consumption and emissions from the combustion engine
reduce.
Here is a selection:
▶ Peter Gutzmer, Chief Technology Officer of the German supplier Schaeffler AG, showed three paths to the next drive future in his presentation: optimization of the combustion engine, 48 volts and high-voltage hybridization. Electric driving also enables the use of transmissions with fewer gears, which saves drivetrain costs, says Gutzmer.
▶ Rolf Bulander, Managing Director of Robert Bosch GmbH and Chairman of the Mobility Solutions division, presented new strategies in addition to the mild hybrid, such as increasing the pressure of gasoline injection to 350 bar or injecting a gasoline/water mixture in gasoline engines.
▶ John Fuerst, Vice President Engineering Powertrain Systems of the supplier group Delphi, presented, among other things, the new gasoline direct injection engine with compression ignition GDCI, which promises the fuel consumption advantages of a diesel engine and low NOx and soot emissions. Such a unit could be ready for production in the next decade, says Fuerst.
▶ Masanori Sugiyama, senior engine developer at Toyota, presented the core technologies developed by the group for the drive diversity of the future. This includes engines and transmissions as well as electronic components, electric motors, inverters and batteries for hybrid electric vehicles. In addition, the hydrogen-powered Toyota Mirai will also be launched in Europe and the USA in autumn 2015.
▶ José Avila, Head of the Powertrain Division at Continental, presented successful strategies for minimizing nitrogen oxides in diesel engines. Continental achieves this, among other things, by placing a compact catalytic converter close to the engine, which heats up more quickly and becomes active earlier. The electrically heatable catalytic converter (e-Kat) serves the same purpose, bringing the catalytic converter structure to temperature in hybrid vehicles when the internal combustion engine has been switched off for a long time in the interest of saving fuel.
▶ VW Head of Development Heinz-Jakob Neußer predicted in his lecture: “Highly efficient TDI and TSI/TFSI engines – ideally in conjunction with the DSG dual clutch transmission – will remain indispensable for the foreseeable future.” The group's new high-speed diesel features highly efficient combustion processes, innovative thermal management, maximum charging thanks to the e-booster as well as new materials and coatings and achieves an output of well over 100 kW per liter of displacement. The also new high-performance 3-cylinder TSI produces an impressive 272 hp and 270 Nm of torque from just one liter of displacement via a monoscroll turbocharger and e-booster. “A great example of how much potential there is still in the combustion engine,” says Neußer.
Friedrich Eichler, head of engine development at Volkswagen, also presented the new 6.0 l twelve-cylinder engine W12 TSI, which is used in the premium models from VW, Audi and Bentley. “With a switchable oil pump, integrated thermal management, dual fuel metering with high-pressure direct and low-pressure intake manifold injection, twin-scroll biturbo charging as well as individual cylinder bank deactivation and two control units, this engine can be operated like four different units as required,” explained Eichler.
