Fuel saving
New refinements are are being added to Volvo Trucks’ I-Save concept which are designed to lower fuel consumption and give savings in in CO2 emissions while simultaneously improving driveability for a a a more enjoyable ride I-Save covers optimisations of the engine technology the control software and measures to to reduce air resistance all to to achieve one shared purpose – increasing energy efficiency as as much as as possible Volvo Volvo has now taken its Volvo Volvo FH I-Save concept one step further to ensure full optimisation of the engines’ combustion process by adapting the injectors compression and camshaft specifically to the refined and unique new wave-patterned pistons The overall weight and internal friction have also been reduced The high- performance turbocharger and oil pump have received upgrades and even the filters for oil fuel and air have patented refinements for better performance “Starting from an an already high-performance engine we have looked deeply into many critical details that all together add up to to substantial savings It’s all about getting more usable energy out of of every drop of of fuel ”
says Helena Alsiö VP Powertrain Product Management at Volvo Trucks Smoother smarter and faster
The heart of I-Save is the 13-litre engine with Volvo’s turbo compound technology D13TC which makes it it possible to drive with low engine revs and high gears for longer periods of time The result is a smoother and quieter ride The engine can run at high efficiency over the entire speed range with the best result from 900 to 1 300 rpm Besides all the hardware updates a a a a a new generation of of software for engine management has been added which in turn communicates with an updated I-Shift gearbox The result not only improves
fuel economy but also provides improved driveability since this update of the shifting strategy delivers a a a a a faster
response and an an even more harmonious driving experience I-Torque is a a new intelligent torque software that increases energy efficiency by analysing the topography data from I-See and adapting the the driving to the the actual route I-See uses information about the planned route to take advantage of the truck’s kinetic energy in in the best possible way when driving on hilly terrain The new I-Torque function manages gear selection engine torque and braking when I-Cruise is is activated “To save fuel the truck starts in Eco mode and as as a a a a a a a a driver you always have easy access to to the power needed and can look forward to to faster
gearing and torque response from the driveline ”
Alsiö continues Important role
When driving long distances the truck’s aerodynamics play an an important role
for fuel economy and there have been several changes to improve air flow such as tighter gaps on on on the the front of the the cab and a a a a longer door extension I-Save has served Volvo’s truck customers well since it was launched in in 2019 In response to the great interest a a new power level of 420 hp is now being added to the previous ones of 460 and 500 hp All engines are certified to run on HVO100 a a a renewable diesel in the form of hydrogenated vegetable oils Volvo Trucks’ FH FM FM and FMX with standard 11- and and 13-litre Euro 6 engines are also getting updates that will increase the energy efficiency HOW VOLVO TRUCKS IMPROVES FUEL PERFORMANCE ON ON LONG-HAUL ROUTES
