As a part of eliminating its dependence on Ford platforms and powertrains, Volvo has previously announced information about its Volvo Engine Architecture (VEA) and Scalable Platform Architecture (SPA), but now we're finally getting some details about what will power some of the Swedish automaker's next-generation products.

The biggest key to VEA on the diesel engines is a new technology Volvo calls i-ART. This system uses unique injectors at each cylinder capable of monitoring fuel pressure and adjusting accordingly to maximize fuel economy and performance and reduce emissions. Looking ahead, Volvo says its four-cylinder engines will be able to offer the power of a six-cylinder and eventually, mixed with some sort of electrification, will be able to rival the performance of a V8 and "turn V8s into dinosaurs."

More details about the new diesel injection technology is posted in the press release below.

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.

Several levels of turbo charging open up for the flexibility to cover the whole range from fuel-efficient derivatives through to high power and torque variants. 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 Derek Crabb.

V8s are dinosaurs

"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 high-tech engine plant in Skövde, Sweden.

      2500 bar is not only an "exceptionally high" a pressure, it's REMARKABLY high. So much in fact, that I'm wondering whether someone got their units mixed up. Pressurized gasses for industrial use are typically stored at a pressure of 200 bar. 2500 bar is more than 36 kpsi, which is more than the pressure needed to cut concrete with a water jet. I can't see why on earth you'd want to run a freakin ' fuel rail at such insane pressures, as you'd have to construct a mother of a fuel rail to withstand that load. Not to mention the compressor to drive it. It's not something you'd typically want to have under the hood of a car. In fact, if Volvo are able to mass-produce an engine with a fuel-rail running at 2500bar, in an affordable car, I'd want them to get into the space program ASAP. Now, had they written 2500 psi, that is something that would be easier to believe. That is still a heck of a lot as far as fuel systems go.

        I actually work in the diesel industry in fuel systems. This pressure is not even new and has been in use on semi-trucks for years. Cummins has had engines in the semi-trucks at close to 2400 for nearly 5 years with a Cummins designed XPI fuel system on their C-Series einge. Even the standard Dodge Ram is currently at 1600 bar and that's not considered high. John Deere tractors also use this type of technology. The product that my company makes are high pressure fuel lines for diesel engines. We have tested lines that are 8mm od x 3.5mm id in excess of 3000+ bar working pressure with 10 million test cycles. This is the type of technology that is required in order to meet the emissions standards that the EPA requires. The cost to industry is more than you can imagine and it gets more difficult to meet these standards with each year. An no, it was not easy to do, but you would be amazed what can be done by engineers given a goal, time and budget.

      Well they already make pretty awesome diesel trucks so this shouldnt be a problem for them
      • 2 Years Ago
      That is a really bad headline. Diesels are already direct injected.

       A main component of the diesel direct injection is the common rail

      Saying that V8s will become dinosaurs is a bit naive. V8s have been evolving. Remember when DOD came out?
      • 2 Years Ago
      Why would it turn V8s into dinosaurs? If anything, they can make V8s that rival V12s, and V12s that rival...the handful of V16s. We are humans, the one thing we will always want is MORE POWER!!!

        True, there will be a day when V8 engines are only found in supercars. Fine with me, if we can still get the same amount of power out of a modern V6 that weighs 200 pounds less than an old V8. Lighter, smaller sized engines not only improve fuel efficiency but also make it easier for the designer to achieve a 50/50 weight balance.

          I'll keep my V8 thanks. A V6 will never be able to replicate the sound of a V8.

          How about a really really small V8 :-)

      Debating between a V8 and a V6....First world problems.

      Put them interesting cars.
