Volvo Trucks cut fuel consumption with new software and upgraded engines

Volvo Trucks has introduced new functions that help drivers save fuel even when cruise control is not activated. The launch of upgraded D13 diesel engines for Euro 3, Euro 4, Euro 5 and EEV markets, together with the new software, enables fuel savings of up to 3%.
Through a combination of new software and hardware upgrades for Euro 3 to 5 markets, Volvo Trucks’ updated D13 diesel engines can save up to three per cent in fuel in long-haul operations.

Volvo Trucks Southern Africa recently highlighted its new fuel saving software and upgraded engines during the Futuroad Expo in Johannesburg.  

The launch of upgraded D13 diesel engines for the local market, which includes Euro 3, Euro 4 and Euro 5 specifications, together with the new software, will enable fleetowners to reach fuel savings of up to 3%.”

”As society changes and develops, our customers are requiring enhanced fuel efficiency for their fleets.  With this new technology and engine hardware, we are assisting fleetowners to achieve better results, and thus saving money and ultimately increasing their profits,” said Marcus Hörberg, Vice President of Volvo Group Southern Africa.  

During his address, Hörberg also touched on Volvo Trucks’ encouraging performance so far this year.

“Taking into consideration the sales statistics up to the end of August 2019, Volvo Trucks has managed to claim the biggest share in the Heavy Duty segment of the South African new truck market for the first time ever, with a 22% market share. We are very proud of this achievement and will continue to work hard to bring our customers only the best products, support and service,” said Hörberg.  “As a result, we have ramped up our capacity at our Durban plant to meet the increased demand for our trucks.”

Volvo Trucks believes in really listening to their customers and are committed to add value to their businesses.

“We want to be true business partners with our customers.  We know that if our customers are more successful with our transport solutions, they will keep returning to Volvo Trucks in the future,” commented Hörberg.

Reducing Fuel Consumption

The new function will be introduced on locally-produced Volvo trucks from January 2020 and is called Volvo Torque Assist. It is intended to reduce fuel consumption by providing more efficient driving when the cruise control is disabled in long haul operations. 

These new functions will help drivers save fuel even when cruise control is not activated.  I-Cruise, Volvo Trucks’ intelligent cruise control, is still the best way to optimise fuel consumption, but sometimes it might not be applicable. 

“In this way we can support the driver to cut fuel costs when driving conditions demand it,” said Hörberg.  

Volvo Torque Assist is designed to give more fuel-efficient driving by automatically adapting the truck’s torque and acceleration to the road topography, the load and speed changes. Another supporting function keeps the amount of injected fuel constant after the engine’s ‘green range’ has been passed. The slightly compromised performance is compensated by improved fuel economy. 

The pedal map has also been recalibrated. A less sensitive pedal creates a smoother torque development, which, in turn, makes the truck easier to control. 

“The new software also gives a more significant result with heavy loads, many slope changes or large speed variations, while drivers transporting lighter loads with constant speed on flat roads will save less fuel,” explained Hörberg.  

The hardware upgrades in the Euro 6 Step D versions of the D13 engine, released earlier in 2019 for European markets, are also being used to raise the standards of the Euro 3 to 5 engines. Internal friction has been reduced with new cylinder liners and new V-shaped oil scraper rings. The turbo efficiency has been improved and the engine management system is upgraded to a newer version with better capacity.
