Scania renews its historic vary of V8 engines for vehicles with 4 energy ranges: 530, 590, 660 and in addition a bomb model of 770 HP with a torque of three,700 Nm, clearly Euro 6. The transmissions have additionally been renewed with the new Opticruise automated transmissions that enhance driving on these heavy automobiles with quicker and smoother gear adjustments and due to this fact better effectivity.
The brand new technology of this 8-cylinder V- diesel engine not solely delivers record-breaking energy but additionally guarantees an general discount in gasoline consumption of as much as 6%.

Options new Scania V8 engines
Among the many 70 improvements featured on Scania’s new V8 engines are decrease inside friction, greater compression ratios, improved after-treatment system and a strong new engine administration system.
All 4 of the brand new V8 engines share the identical platform and handle to be extra environment friendly (-3%) additionally due to the introduction of the newest exhaust gasoline after-treatment applied sciences.
The intention is to fulfill present and future Euro 6 requirements on nitrogen oxides (NOx) and particulate matter, not solely when the car is new but additionally all through its life. The scheme options the SCR system, a sturdy mounted geometry turbocharger (FGT) with ball bearings and single-bank exhaust manifolds.
Double AdBlue injection on Scania vehicles
Among the many technical options of the new Scania V8 engines the truth that the ‘ AdBlue is injected twice: one straight after the engine brake and a place within the “commonplace” inside the silencer.
On this manner, because the temperature is greater close to the exhaust manifold, there may be an enchancment within the evaporation of the additive in the course of the low load cycles. The after-treatment technique improves and in addition contributes to better gasoline economic system.
Excessive strain diesel pump
Within the new Scania V8 engines, the new high-pressure diesel gasoline pump is optimized to reduce engine oil consumption. The compression ratio and most cylinder strain have been elevated to enhance combustion and gasoline economic system.
To enhance uptime and efficiency, general strain and injection management are supported by much more exact diagnostics that may extra precisely calculate how a lot gasoline is required and when.
Scania Opticruise automated gearbox
The brand new Scania V8 engines along with report energy ranges but additionally a discount in gasoline consumption which, underneath the fitting circumstances, can attain as much as 6% . The credit score for this enchancment should, nonetheless, additionally and above all go to the new automated Opticruise transmission which has nothing in widespread with the earlier model.
New within the Opticruise gearbox
Through the design and growth of the brand new powertrain, Scania engineers targeted significantly on excessive torque at low engine speeds, power losses and inside friction which had been lowered by greater than 50%.
Using all-aluminium packing containers of lowered dimensions led to a weight discount of roughly 60 kg. One other key consequence was the discount of noise, which is crucial to fulfill future noise emission requirements.
All electronics are new and handle pneumatic actuators and shaft brakes, for quick, clean and correct shifting.
Eight gears additionally in reverse on the Opticruise gearbox
For reverse, Scania engineers have adopted a brand new method, as an alternative of rotating the primary drive shaft in the other way with a devoted gear on the gearbox, the brand new Opticruise makes use of the planetary multiplier on the wheel hubs to reverse gear.
This answer permits for eight reverse gears (non-obligatory) with a velocity of as much as 54 km / h , a helpful operate when, for instance, tipper automobiles must reverse lengthy distances (as in tunnel development).
New, extra compact and extra sturdy gearbox
The brand new Opticruise transmissions are shorter and extra compact than the presently hottest Scania transmission, the GRS905 . By utilizing solely two synchronizers as an alternative of seven, the shafts are capable of transmit the next torque . This permits the usage of barely wider gearboxes that may deal with greater general lots and are extra sturdy.
Energy take-offs for attachments and hydraulic pumps, clever PTO options
Among the many PTO options developed with the intention of satisfying particular functions, a full vary of 9 completely different energy take-offs will quickly be accessible , with much less power losses and nice flexibility due to modularity. The brand new interface on the gearbox, with lubrication, will permit you to set up even heavier tools corresponding to hydraulic pumps.
Tremendous-powerful 770hp Scania V8 engine, what’s all this energy for?
On the head of the brand new Scania V8 household , briefly, there may be the brand new DC16 123 engine which with its 770 HP and three,700 Nm of torque replaces the earlier prime quality which reached “solely” 730 HP. A formidable energy, which, nonetheless, maybe appears extreme for the typical wants of our logistics.
Nonetheless, “a rise within the demand for automobiles able to dealing with whole lots of 60 t or extra is underway and the quickest method to enhance transport effectivity is the usage of longer car combos. and heavy “.
Once more in accordance with the producer, the best demand for energy comes from these states the place the very best general lots are allowed , ie in Northern Europe. Nonetheless, the V8 can also be very fashionable in Italy and Spain . At low latitudes we’re additionally very delicate to the “pure pleasure and thrill of driving such an impressive work software.”
Ardour for Scania V8 engines!
In brief, in actuality, the essence of the Scania V8 is ardour , this engine has gone via over 50 years of historical past as an ideal synthesis on the one hand of ardour and satisfaction, on the opposite efficiency, gasoline economic system, innovation and expertise.
Scania’s first 8-cylinder V engine was offered in 1969 , it was designed to hold out probably the most demanding missions, but it surely rapidly grew to become a legend. Through the years the V8 engine vary has undergone a technique of steady enchancment , till right now. This technology was designed to accompany us over the subsequent ten years.
Sustainable transition and Diesel on vehicles
The Swedish producer has additionally not too long ago launched the primary vary of electrical industrial automobiles. Nonetheless, these new generations of V8 engines and Scania transmissions show that automobiles with inside combustion engines (Diesel or Biodiesel), for higher or for worse, will proceed to characterize an answer to put money into once more within the transition to sustainable transport.
