Majo Cecur, engineering manager for Eaton’s Valvetrain business unit in Torino, Italy, was a featured speaker at the first International Engine Congress in Baden-Baden, Germany. This two-day event, jointly developed by ATZlive and VDI Wissensforum, drew more than 380 industry leaders and engineers from vehicle manufacturers, suppliers and research organizations. The group discussed the latest technology trends and challenges for internal combustion engines in both passenger cars and commercial vehicles. Topics included charge exchange, exhaust after-treatment devices, engine management, thermal management for gasoline, diesel and natural gas engines. Panelists also examined the design differences between conventional combustion engines and those with hybrid-electric range extenders. Panelists agreed that the internal combustion engine likely will remain the dominant power source for the transportation industry for the next few decades. But they said all engine components, functions and systems must be further optimized to meet increasingly stricter and more complex environmental and testing requirements, such as new European Union rules aimed at reducing harmful carbon dioxide emissions and the Worldwide Harmonized Light-Duty Test Cycle..
Eaton Technologies Help Improve Fuel Economy As one of 20 exhibitors at the event, Eaton showcased its latest valvetrain and supercharger products. In his presentation, Cecur discussed valvetrain solutions such as variable valve actuation (VVA), variable valve lift (VVL) and cylinder deactivation (CDA) for passenger cars, as well as advanced valvetrain systems for heavy-duty diesel engines. “The congress was well-attended and already is a huge success in its first year,” said Cecur. “The main emphasis was on future fuel efficiency improvements. In order to fulfill legislation requirements, advanced valvetrain systems using VVA, VVL and CDA will be needed. This provides growth opportunities for Eaton in the European market.” Eaton already has several products available that help enable powertrain downsizing and downspeeding, and continues to develop new technologies to support the trend.
