Twin SCR system for Deutz V6 and V8 engines

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.

Deutz TCD12 V6 diesel engine
201 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.

Deutz’s SCR package uses a combined DOC/SCR catalyst as the first phase of exhaust treatment, followed by a ‘clean-up’ catalyst. While slightly bulkier than a single SCR system, the dual SCR package uses one tank and two dosing systems but does not use twice as much fluid, said the company.

These latest TCD12 and TCD16 engines are said to offer up to 8% more performance with average fuel consumption reduced by around 5% compared to the previous Tier 4 interim versions. However, expect DEF consumption to increase by 2%, said Deutz.

  • Less damage for a low cost with SKF’s new development
    February 13, 2013
    More machines, both mobile and stationary, are using centralised lubrication which helps to ensure that all points receive the required amount of lubrication, as lack of it could result in expensive bearing damage. Escaping lubricant can have a significant negative impact on the environment, and can also incur expensive clean-up and disposal costs. SKF has developed the Lincoln Hose Connection Control, which can be operated between -50 to +70 OC, this unit shows immediately and reliably when damage occurs.

  • C-series CX470 excavator takes centre stage on Case’s INTERMAT stand
    January 6, 2017
    A 6% increase in lift capacity, greater digging efficiency, reduced emissions and up to 5% lower fuel consumption are the benefits of Case’s new CX470C excavator. The 47 to 50tonne machine has a 9.8litre Stage IIIB engine delivering 270kW at 2,000rpm which contributes to a 5% increase in fuel efficiency and 5% faster cycle times. Some of the savings come from a Boom Economy Control, which automatically reduces engine revs and hydraulic power to the boom when speed and power are not a priority.

  • First public outing for Liebherr tower crane at INTERMAT
    January 6, 2017
    Liebherr used INTERMAT 2012 to show its new 380 EC-B 16 Litronic flat-top crane. The 380tonne unit tops the 15-model range, which starts from 50tonnes. The new “flagship” can lift loads of up to 3,400kg at its 75m maximum radius. With the Litronic system, the 380 EC-B 16 can provide up to 20% more load lift at the push of a button. This is achieved by integrating the load-moment limiting system, the ABB operating-range limiting system and the MDA machine data evaluation program.
