Volvo to bring to market world\'s first i-ART injection technology

Along with an eight-speed automatic gearbox later this year
Apr 23, 2013


Volvo has announced that its new Volvo Engine Architecture (VEA) series of powerplants will be introduced to its cars later this year. To complement the new line of engines, Volvo will also introduce to the world the i-ART technology that \"helps to cut fuel consumption in the new diesel engines.\"

According to the Swedish carmaker, instead of using a single pressure sensor found in traditional common-rail engines, the pressure feedback from each fuel injector in the i-ART system makes it possible to continuously monitor and adapt fuel injection per combustion in each of the four cylinders.

\"Increasing the rail pressure to an exceptionally high 2,500bar, while adding the i-ART technology, can be described as the second step in the diesel revolution,\" said Volvo vice president for powertrain engineering Derek Crabb. \"It is a breakthrough comparable to when we invented the groundbreaking lambda sensor for the catalytic converter in 1976. It\'s another world-first for Volvo.\"

The i-ART system works by having a small computer on top of each injector which monitors injection pressure. Through the data gathered by the computer, the self-adapting i-ART system makes sure that the ideal amount of fuel is injected during each combustion cycle. The combination of higher injection pressure and i-ART technology reportedly gives the customer an engine with improved fuel economy, considerably lower emissions and high-performance output as well as a powerful sound character.

Besides the VEA line of engines, Volvo will also introduce a new eight-speed automatic gearbox that \"contributes to a refined drive and excellent fuel economy.\"

\"The new powertrains will boost driving pleasure through their agile yet smooth responsiveness, and the seamless character of the new eight-speed automatic,\" Crabb added.
