In-depth modelling and testing conducted by Caterpillar Inc. has shown that the 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 this practical and cost-effective increase in fuel efficiency for HDVs, the ETI programme used a demonstration heavy-duty CAT® 725 Articulated Truck, featuring a range of the energy saving technologies.
The demonstration off-road vehicle, designed to showcase the robust nature of the technology, is fitted with an optimal selection of 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 emissions - but remains one of the most difficult sectors for the United Kingdom (UK) to decarbonise.
Chief Technical Officer
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.
Today we are celebrating Caterpillar’s achievements on the technology demonstration off-road vehicle, which includes technologies that have a wide applicability across the full range of land-based HDVs. Work on the full range of HDVs will be published later this year, and we hope the wider industry as well as Caterpillar will be able to benefit from these insights.
The Caterpillar technology demonstration vehicle has been modified based on previously identified technologies through the ETI’s £40 million HDV programme. The off-highway demonstration vehicle project is the first phase of outputs from the ETI’s HDV programme which is exploring how the UK’s HDV sector can successfully decarbonise.
