Apologies if you've all read about this already, but local dealer just sent a link via Facebook to the following information.....


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.

He adds: "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."

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.

Launched autumn 2013
Volvo Car Group will launch the Volvo Engine Architecture in autumn 2013. With VEA, Volvo will also introduce a new 8-speed automatic gearbox that contributes to a refined drive and excellent fuel economy.

Diesel common rail and petrol direct injection are standard in the upcoming modular range of diesel and petrol engines.

Just read an article in Auto Express concerning the new XC90, apparently it will only have 4cyl engines. does anybody know if theres any truth in this?

Possible - the third paragraph in the press release specifically refers to four cylinders; I guess the stupendously high rail pressure will more than compensate for an apparently modest capacity engine :-)

I read somewhere ages ago that in the future Volvo will move towards 4 cylinder diesel engines.

Iirc 2012 was the last year for the 5 cylinder engines so it could be there going 4 cylinder such a shame.

The change is linked ignoring the V40 sized next car all the bigger volvos will be on the SPA this will only accept from understanding a maximum of 4 cylinder engines there will be possibility of 3 cylinders been seen to in the SPA, the design of engines being the VEA in various forms diesel or petrol.

Regarding the V40 sized next car it will be on a new shared platform with the same scaleable features as the SPA. There has been no word on who the share will be with the time for implementation etc.

Although what is making me go yikes is the thought of the cost of those injectors needing change!

Sounds impressive, but it sounds like it will be extraordinarily expensive when it goes wrong.

The 5 cylinder petrol turbo in 2 litre form ( 2 power levels ) and 2.5 litre form ( 260 bhp ) has just been launched in the V40 Cross country :-) not dead yet!
