New technology to cut fuel consumption, CO2 emissions significantly
STUTTGART/ BERLIN — Using technologies available on the market, the fuel consumption, and therefore the CO2 emissions, of modern truck combinations can be reduced by a double-digit percentage.
This was the finding of a field test, the results of which were presented this week in Berlin by Daimler Trucks together with the project participants. These results from field tests with the name Efficiency Run will be of great significance in the future for achieving CO2 targets for road freight transport.
This is because the Efficiency Run has demonstrated that fuel consumption, and therefore also CO2 emissions, can be significantly reduced — also at lower cost — if optimisation efforts focus not just on the engine of the tractor unit, but on the vehicle as a whole. Additional significant CO2 reductions, which could add up from factors like specific fuels, fleet operations or driver trainings, have not yet been considered in this field test.
The series of tests was conducted by Daimler Trucks in cooperation with the leading German logistics companies DB Schenker Logistics, Grosse-Vehne and Elflein. This involved genuine freight being driven on genuine routes under realistic conditions. The tests were supervised in detail by the Dekra testing organisation, which laid down the test conditions, carried out the measurements and evaluated the results. One of the key results: The two Mercedes-Benz Actros standard semi-trailer combinations that were optimised for the Efficiency Run each consumed around 12 to 14% less fuel than standard semi-trailer combinations of the respective transport companies based on their fleets in 2014. The Efficiency Run also investigated the potential of the Long Combination Vehicle — once again with a clear result. In the test, the standard Long Combination Vehicle showed a reduction in consumption of around 17% compared with the standard semi-trailer combination used in volume-based transport.
The goal now is to adopt an integrated approach with commercial-vehicle manufacturers, body/tyre suppliers, logistics companies and, last but not least, politicians.
Daimler Trucks presented this concept together with other European manufacturers at the 2014 IAA for Commercial Vehicles. The objective of the integrated approach is to optimise the entire truck/transport system.
In addition to the tractor unit, consideration is given also to the semitrailer (e.g. weights and dimensions, air resistance, lightweight design), tyres (e.g. rolling resistance, air pressure, single tyres) and fuel (e.g. biofuel, natural gas). Yet the integrated approach also attaches importance to vehicle operation (e.g. driver training, cargo pooling), infrastructure and the issue of fleet renewal. The Efficiency Run has now demonstrated that the integrated approach works in realworld practice. — Supplied.
