Volvo Car Group launches world-first injection technology in the new VEA engine family

Volvo Car Group's new engine family VEA (Volvo Engine Architecture) will be launched this autumn with world-first i-ART technology that helps to cut fuel consumption in the new diesel engines.

By featuring pressure feedback from each fuel injector instead of using
a traditional single pressure sensor in the common rail, i-ART 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 2,500 Bar, while adding the i-ART technology, can be described as the second step in the diesel revolution. 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," says Derek Crabb, Vice-President Powertrain Engineering at Volvo Car Group.

"Each injector has a small computer on top, which monitors injection pressure. Using this information, the self-adapting i-ART system makes sure that the ideal amount of fuel is injected during each combustion cycle," he added.

The combination of higher injection pressure and i-ART technology gives the customer an engine with improved fuel economy, considerably lower emissions and high performance output as well as a powerful sound character.
