Linde boasts the cleanest diesel trucks

Diesel trucks from Linde Material Handling have the lowest exhaust emissions in the 2.5 to 3.5-tonne high-volume segment

As part of its sustainability strategy, Linde Material Handling (MH) uses environmental performance evaluations to analyse and document the environmental impact of products over their entire life cycle. The exhaust emissions of the company’s combustion-engine trucks have now been evaluated as part of this process, and the result is sensational: In the largest sales segment—trucks with a load capacity of between 2.5 and 3.5 tonnes—Linde diesel trucks are the cleanest! Linde diesel trucks also produce some of the lowest emissions in the other load-bearing capacity classes of up to 2.5 tonnes and from 4 to 8 tonnes.

With its Linde H25 to H35 EVO diesel trucks, Linde MH is the only truck manufacturer to meet the stringent Stage IIIB of emissions directives 97/68/EC and 2004/26/EC for mobile equipment, which have applied to the 37 to 55-kW power class since January 2013. Equipped with a modern common-rail diesel engine delivering 44 kW of power and a particle filter fitted as standard, these vehicles do not only meet the statutory limits for harmful emissions — they are well below the limits. The value for emitted particulate matter (PT) is approximately 83% below the limit, hydrocarbons s (HC) and nitrogen oxides (NOx) are 26% below the limit and the figure for carbon monoxide (CO) —a gas that can have serious effects on the respiratory system—is as much as 99% below the limit.

What’s more, by installing a special axial piston displacement pump for the lifting hydraulics, as well as an electric fan, the overall efficiency of the new “EVO models” has been significantly increased. In practice, the intentionally large design of the variable displacement pump ensures a reduction in engine speed of up to 1200 rpm when performing all lifting operations, resulting in fuel savings of 20% at an average compared with previous models, which were already fuel efficient.

The combination of an innovative internal combustion engine, an economical hydrostatic drive system and greater energy efficiency ensures that, today, only a very small amount of harmful exhaust gases are released into the environment from the exhausts of Linde diesel trucks. Based on the fuel consumption figures from the VDI work cycle, the emissions produced by a Linde diesel truck in the specified load-bearing capacity range demonstrate a reduction of 98% in diesel particulates and carbon monoxide. At 10,000 operating hours, the quantity of harmful substances produced by a Linde H35 D EVO compared with the previous model is reduced by an impressive 285 kilograms in total or 39 percent accordingly. This reduction lessens both the impact on all people working around the truck and the effect on the environment to a considerable extent.

“Without compromising the truck’s performance, we have succeeded in reducing the diesel particulate matter emitted by a 3.5 diesel truck during this period of operation from 30 kilograms to just 500 grams, and we have pushed carbon monoxide emissions down from 159.4 kilograms to a mere 3.3 kilograms. By achieving this, Linde MH has affirmed its position as a technology leader in the industry, as the company constantly succeeds in increasing the added value of its products through innovation,” explains Ralf Dingeldein, Vice President of New Trucks at Linde MH.
