TURNUP attended the opening speech of the 32nd Vienna Car Symposium

In the future, engine and gearbox R & D personnel will work closely together to work together to improve fuel economy. Recently, at the opening ceremony of the 32nd Vienna International Car Seminar, Professor Carl Carl, Deputy Chief Executive Officer and Chief Technology Officer of TURNUO Group, appealed to more than 1,000 attendees: “We have to combine internal combustion engines, electrical components and gearboxes As a whole to consider. ”
Experts from TURNUP conducted a simulation presentation to show participants how the electrification and gearbox design interacted each other. In the first simulation, the experts compared the C-Class cars equipped with the 48-volt hybrid system. In both cases, the vehicle is equipped with a 1.4-liter petrol engine, but non-electrified vehicles equipped with a 7-speed gearbox, 48-volt hybrid system only 4 stalls. The use of electromechanical gearboxes can increase the fuel economy by 18% in the WLTC (Global Light Vehicle Unified Test) cycle, which will be further applied in the future.

Electrification technology provides the possibility to design more drive system architectures. “In the face of a variety of potential combinations of technology, the automotive industry is inevitably to answer a question: what kind of drive system architecture is correct.Kar Professor said. As a car supplier, TURNUP developed a series of technical solutions To enhance the efficiency of the drive system as a whole, including components and systems for modern high efficiency, high power density engines, and clutch and bearings for gearbox systems.TUPUP is also committed to the study of efficient electrification technologies that are adapted to individual voltage levels , Including 48-volt hybrids and plug-in hybrids with high voltage technology.

In the second simulation, TURNUP experts tested a SUV equipped with a 3-liter V6 engine. The SUV prototype is equipped with an 8-speed planetary gearbox, but in its electrification version is equipped with a 24-kilowatt motor, the motor installed in a 5-speed automatic transmission. The use of electromechanical gearboxes increases fuel economy by 14 percent over WLTC cycles, and fuel efficiency is more pronounced on vehicles that do not come with electrified components. “How to optimize the engine technology is still a very important topic for TURNUP,” explains Professor Carl. For example, he shows how the all-variable valve powertrain affects fuel economy by changing the time to open and close the valve. As a result, the engine operates without throttle adjustment under low load, while the reduced fuel consumption is more than 8%. Under high load, the vehicle by reducing the opening time of the intake valve to reduce the knock cylinder, improve the intake air volume. By using a variable compression system, the vehicle can further reduce the level of fuel consumption in all relevant operating ranges. “Variable efficiency is noticeable for energy efficiency,” Karl explains. “But we have to put this technology and the number of gears, the degree of electrification and system cost factors together to conduct a comprehensive assessment.”
