Caterpillar is introducing a revised line-up of 20-24 tonne E Series crawler excavators at Intermat 2012. The 320E, 323E and the reduced radius 320E RR adopt the EU Stage IIIB Cat C6.6 ACERTTM engine, providing reduced emissions and fuel consumption savings of up to 11% compared to other D Series models. A wider range of cab seating, including heating and cooling options, comes with the new E Series crawler excavators. Time delay lighting, additional safety handrails and improved serviceability are also sai
Deutz has adopted a dual SCR after-treatment system on its high output TCD Vee engines to meet Tier 4 final emissions standards.
Using a dual SCR system, the water-cooled 90-degree V6 12litre and V8 16litre engines, with power outputs from 390-520kW, were found not to require cooled EGR, DOC or DPF technologies. Compared to a similar engine using cooled EGR, Deutz said its TCD12 and TCD16 can operate with a cooling package that is around 20-25% smaller, improving installation packaging for OEMs.
