New engine emission regulations pose major challenges for engine manufacturers - Geoff Ashcroft reports. The arrival of emissions regulations in January for engines over 130kW has meant that engine makers have adopted varied technologies to meet and exceed those goals. For the end user though, buying new kit that complies with Tier 4 Interim/Stage IIIB emissions regulations is likely to carry additional costs.
Komatsu Europe has premiered its new next-generation WA475-11 and WA485-11 wheeled loaders, which the manufacturer says represent a leap forward in performance and efficiency.
At the heart of new Dash 11 generation wheeled loaders is a newly developed Komatsu diesel engine which is characterised by extremely high torque in the low-speed range. This new engine is combined with a Komatsu-designed hydro-mechanical-transmission (HMT), resulting in excellent performance, power reserves, fuel efficiency and ease of operation for all transport and loading tasks.
Deutz and Volvo Group are to continue their joint engine technology partnership, with a view to developing new low emission, fuel efficient engines. This new deal carries on from an agreement signed in 1998 for the development and supply of 4-7litre diesels. The agreement was concluded with a term of 15 years and is due to end in 2013, so the new supply agreement will come into effect from 1st January 2014.
