Heavy duty vehicle technology demonstration improves fuel efficiency by 28%
In-depth modelling and testing conducted by Caterpillar has shown that technologies developed through the Energy Technologies Institute’s (ETI) heavy duty vehicle (HDV) programme have the capability to improve the fuel efficiency of a technology demonstration articulated truck by up to 28%.
To demonstrate the cost-effective increase in fuel efficiency for HDVs, the ETI programme used a demonstration heavy-duty CAT® 725 Articulated Truck, featuring a range of energy saving technologies, including a continuously variable transmission (CVT), a hydraulic energy storage system (KERs), a high efficiency engine air system and optimised cooling systems. The ETI believes that the demonstration vehicle is a valuable step forward on the path to decarbonising the HDV sector.
The HDV sector in the UK, which includes all trucks, marine vessels, buses and off-road machines, currently contributes to 8% of the country’s greenhouse gas (GHG) emissions – but remains one of the most difficult sectors to decarbonise. Chris Thorne, Chief Technology Officer for the ETI’s HDV programme comments: ‘The development of energy saving technologies for HDVs has been really important to us. We believe that the reduction of carbon emissions in this sector is critical for the UK to reach its climate goal targets.’
