A variable timing phase for both rollers were used. The valves are driven directly, without the use of a lever. The hull was made as a heavily ribbed aluminum cast.
The injector was placed vertically, right next to the spark plug. In this solution, called the GUIDED spray electrode of the spark plug electrodes are located in a cone injected fuel, the cloud of a rich mixture does not have to be reflected from the Denka Tłoka.
As if the engine is cold, the fuel does not fall on the piston and the walls of the cylinder, thus preventing the excessive emission of hydrocarbons. The vertical placement of the injectors is also used in engines, among others BMW, Mercedes, and recently also Nissan. Volvo uses six-wheeled injector and injection pressure of 100 bar.
It is difficult to find revolutionary solutions in the new Volvo engine. Nevertheless, it can be considered a modern and non-competitive competition. Alarmingly "trimmed" torque in T4 version. Competition performs similar treatments, in the end "240 Nm in the range 1600 – 5000 rpm" better sounds than "300 nm at 2500 rpm". The OverBoost function increases the moment to 270 NM must be enough.
