Scania renews its historic range of V8 engines for trucks with four power levels: 530, 590, 660 and also a bomb version of 770 HP with a torque of 3,700 Nm, obviously Euro 6. The transmissions have also been renewed with the new Opticruise automated transmissions that improve driving on these heavy vehicles with faster and smoother gear changes and therefore greater efficiency.
The new generation of this 8-cylinder V- diesel engine not only delivers record-breaking power but also promises an overall reduction in fuel consumption of up to 6%.
Features new Scania V8 engines
Among the 70 innovations featured on Scania’s new V8 engines are lower internal friction, higher compression ratios, improved after-treatment system and a powerful new engine management system.
All four of the new V8 engines share the same platform and manage to be more efficient (-3%) also thanks to the introduction of the latest exhaust gas after-treatment technologies.
The aim is to meet current and future Euro 6 standards on nitrogen oxides (NOx) and particulate matter, not only when the vehicle is new but also throughout its life. The scheme features the SCR system, a robust fixed geometry turbocharger (FGT) with ball bearings and single-bank exhaust manifolds.
Double AdBlue injection on Scania trucks
Among the technical features of the new Scania V8 engines the fact that the ‘ AdBlue is injected twice: one directly after the engine brake and a position in the “standard” within the silencer.
In this way, as the temperature is higher near the exhaust manifold, there is an improvement in the evaporation of the additive during the low load cycles. The after-treatment strategy improves and also contributes to greater fuel economy.
High pressure diesel pump
In the new Scania V8 engines, the new high-pressure diesel fuel pump is optimized to minimize engine oil consumption. The compression ratio and maximum cylinder pressure have been increased to improve combustion and fuel economy.
To improve uptime and performance, overall pressure and injection control are supported by even more precise diagnostics that can more accurately calculate how much fuel is needed and when.
Scania Opticruise automated gearbox
The new Scania V8 engines in addition to record power levels but also a reduction in fuel consumption which, under the right conditions, can reach up to 6% . The credit for this improvement must, however, also and above all go to the new automated Opticruise transmission which has nothing in common with the previous version.
New in the Opticruise gearbox
During the design and development of the new powertrain, Scania engineers focused particularly on high torque at low engine speeds, energy losses and internal friction which were reduced by more than 50%.
The use of all-aluminium boxes of reduced dimensions led to a weight reduction of approximately 60 kg. Another key result was the reduction of noise, which is essential to meet future noise emission standards.
All electronics are new and manage pneumatic actuators and shaft brakes, for fast, smooth and accurate shifting.
Eight gears also in reverse on the Opticruise gearbox
For reverse, Scania engineers have adopted a new approach, instead of rotating the main drive shaft in the opposite direction with a dedicated gear on the gearbox, the new Opticruise uses the planetary multiplier on the wheel hubs to reverse gear.
This solution allows for eight reverse gears (optional) with a speed of up to 54 km / h , a useful function when, for example, tipper vehicles have to reverse long distances (as in tunnel construction).
New, more compact and more robust gearbox
The new Opticruise transmissions are shorter and more compact than the currently most popular Scania transmission, the GRS905 . By using only two synchronizers instead of seven, the shafts are able to transmit a higher torque . This allows the use of slightly wider gearboxes that can handle higher overall masses and are more durable.
Power take-offs for attachments and hydraulic pumps, intelligent PTO solutions
Among the PTO solutions developed with the aim of satisfying specific applications, a complete range of 9 different power take-offs will soon be available , with less energy losses and great flexibility thanks to modularity. The new interface on the gearbox, with lubrication, will allow you to install even heavier equipment such as hydraulic pumps.
Super-powerful 770hp Scania V8 engine, what is all this power for?
At the head of the new Scania V8 family , in short, there is the new DC16 123 engine which with its 770 HP and 3,700 Nm of torque replaces the previous top of the range which reached “only” 730 HP. An impressive power, which, however, perhaps seems excessive for the average needs of our logistics.
However, “an increase in the demand for vehicles capable of handling total masses of 60 t or more is underway and the fastest way to increase transport efficiency is the use of longer vehicle combinations. and heavy “.
Again according to the manufacturer, the greatest demand for power comes from those states where the highest overall masses are allowed , ie in Northern Europe. However, the V8 is also very popular in Italy and Spain . At low latitudes we are also very sensitive to the “pure joy and thrill of driving such a magnificent work tool.”
Passion for Scania V8 engines!
In short, in reality, the essence of the Scania V8 is passion , this engine has gone through over 50 years of history as a perfect synthesis on the one hand of passion and pride, on the other performance, fuel economy, innovation and technology.
Scania’s first 8-cylinder V engine was presented in 1969 , it was designed to carry out the most demanding missions, but it quickly became a legend. Over the years the V8 engine range has undergone a process of continuous improvement , until today. This generation was designed to accompany us over the next ten years.
Sustainable transition and Diesel on trucks
The Swedish manufacturer has also recently launched the first range of electric industrial vehicles. However, these new generations of V8 engines and Scania transmissions demonstrate that vehicles with internal combustion engines (Diesel or Biodiesel), for better or for worse, will continue to represent a solution to invest in again in the transition to sustainable transport.
According to Alexander Vlaskamp, Executive Vice President, Head of Sales and Marketing at Scania , “During the transition to fossil- free transport , we must all do everything possible to improve the current situation. You cannot let your house burn down simply because you are building a new one. The transition must be gradual ”.
