has created a new, adaptable fuel injector for diesel engines that it able to adjust fuel pressure for each cylinder. Volvo promises that this technology will be available in some of its cars in the fall. 

Volvo calls the new technology i-ART, and it uses a small computer on top of each injector to monitor and control pressure. It also allows for higher fuel pressures than current injectors. Traditional diesel engines have a single pressure sensor that could only change the pressure for all of the injectors. The i-ART injectors can change fuel pressure at each combustion stroke, which Volvo says will improve fuel economy, emissions and power for its diesel engines. 

"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," said Derek Crabb, Vice President Powertrain Engineering at Volvo Car Group.

The i-ART injectors will launch on the new Volvo Engine Architecture family of diesel engines in the fall. At the same time it will also introduce a new eight-speed automatic. 

Volvo is making big promises for the new engine family. It believes that they will offer more power than current six-cylinder engines and better fuel economy than current four-cylinders. With its hybrids, it believes that power will rise to the level of V8s but with even better-than four-cylinder fuel economy.
