New injection technology to cut fuel consumption in new diesel engines
Volvo Car Group's new engine family, the Volvo Engine Architecture (VEA), will be launched this September with the world-first i-ART technology that helps to cut fuel consumption in Volvo's new diesel engines.
The i-ART features small computer on top of each injector that monitors pressure feedback instead of using a traditional single pressure sensor in the common rail, making 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.
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. Aside from the VEA, Volvo will also introduce a new 8-speed automatic gearbox to help contribute to a refined drive and excellent fuel economy.
"We will create smaller, more intelligent engines with so much power that they will turn V8s into dinosaurs. Our four-cylinder engines will offer higher performance than today's six-cylinder units and lower fuel consumption than the current four-cylinder generation. On top of that, electrification will bring us up into power figures in today's V8-territory," says Derek Crabb.
The engines will be built at Volvo Car Group's engine plant in Skövde, Sweden.
