Continental reduces fuel consumption of commercial vehicles by as much as 6 litre per 100 km.
With its innovations for commercial vehicles, Continental can achieve fuel savings of up to 6 litre per 100 km (Figure determined on the following basis: 350 kW truck, 40-metric-ton gross vehicle weight, Euro 6 exhaust standard, automated manual transmission on a freeway with varying elevation and road curvature at a typical speed of 85 km/h). This value is a result of the systematic implementation of all the technologies available during series production and development. “We envisage great potential for future optimisation in fleet consumption. Our innovations – some of which are currently in the design phase and some of which are undergoing preliminary development – offer additional potential for reducing consumption by as much as 2 litre per 100 km,” explains Nikolai Setzer, who is a member of the Continental Executive Board. This calculation takes account of more than 20 different technologies that either have recently been implemented in series production or are currently undergoing development. Continental is thereby improving the efficiency of commercial vehicles, cutting CO2 emissions, and improving the cost efficiency of goods transportation.
Some of the latest solutions – including reduced-weight air springs, fuel-saving tyres, and a smaller diesel oxidation catalyst – were displayed at this year’s International Motor Show Commercial Vehicles.
Modern commercial vehicles and buses are subject to exacting demands when it comes to efficiency. To improve the efficiency and cost-effectiveness of goods transportation, payload capacity is to be increased in compliance with statutory limits on axle loads. Reducing the weight is not just about reducing fuel consumption and, in turn, decreasing operating costs, but also brings other advantages, too: For example, with the weight-reducing air spring family from Continental, forwarding agents can gain 12-15 kg of payload capacity per axle. With a service life of 400,000 km, CO2 emissions drop by 200 kg as a result. In comparison with conventional steel pistons, this means as much as 75 per cent less weight, thanks to the use of a special plastic.
At the International Motor Show Commercial Vehicles, Continental has unveiled an innovative solution for close-coupled exhaust aftertreatment on heavy-duty commercial vehicles. By positioning the diesel oxidation catalyst (DOC) near the engine, its volume can be reduced by approximately 30 per cent. At the same time, use of the newly developed catalyst substrate in a Crossversal Structure (CS) design enables a further 20 per cent decrease the amount of materials used and the weight of the DOC. In addition, the diminished heat loss and high conversion efficiency of the innovative CS cell structure will help to meet future NOx emission limits, such as the CARB 2023 regulation (CARB: California Air Resources Board) in the USA. Due to the higher working temperature in the DOC, the subsequent injection of urea solution can begin sooner. In addition to the DOC, the solution showcased in Hanover will include the urea metering system integrated in the tank, the Selective Catalytic Reduction (SCR) controller and the metallic catalyst substrate for 100 per cent evapouration of the urea solution.
At the commercial vehicle exhibition, Continental introduced its new Conti EfficientPro line of tyres for the steering and drive axles. These tyres, featuring optimised rolling resistance, have been developed specially for long-distance transport on freeways.
In developing the Conti EfficientPro, Continental has built upon tried-and-tested technologies already used in the EcoPlus tyre series. Thanks to special rubber compounds for the multi-ply structure of the tread and optimised rolling properties, the rolling resistance of the Conti EfficientPro has been reduced even further. Compared with the Conti EcoPlus tyre, a 40-metric-tonne semi-trailer truck fitted with Conti EfficientPro tyres on the steering and drive axles achieves additional fuel savings of up to 0.64 litre over
100 km. Over an annual distance covered of 120,000 km, this equates to a reduction in CO2 emissions of more than 2 metric ton per year.
