Volvo has announced the creation of a new family of diesel engines, including a new fuel injection technology.
Volvo Car Group’s new engine family VEA (Volvo Engine Architecture) will be launched this autumn with what the company said is a world-first, the i-ART technology.
Per Volvo, the i-ART technology helps to cut fuel consumption in the new diesel engines.
Volvo explained that 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.
The Swedish car company stated that 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.
“Each injector has a small computer on top,” added Crabb, “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.”
Volvo Car Group will launch this new Volvo Engine Architecture in autumn 2013. Along with it, Volvo will also introduce a new 8-speed automatic gearbox that, said Volvo, contributes to a refined drive and excellent fuel economy.
Diesel common rail and gas direct injection are standard in the upcoming modular range of diesel and petrol engines.
Several levels of turbo charging open up for the flexibility to cover the whole range from fuel-efficient derivatives all the way to high power and torque versions.
In order to cover all customer requirements, certain engines will also gain added performance via electrification or other spearhead technology.
“The new powertrains will boost driving pleasure through their agile, yet smooth, responsiveness and the seamless character of the new 8-speed automatic,” says Crabb.
Volvo did not mention any other technical details about this new VEA family, including whether this family is completely new or based on the current generation of engines. Displacement, cylinder count and performance info will have to wait until Volvo is ready to lift the veil on them.
We do know there will be four and six cylinder engines, which may mean the end of the current five-cylinder offered; reading between the lines, the V8 will also disappear.
“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 Crabb.
The engines will be built at Volvo Car Group’s engine plant in Skövde, Sweden.
