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.

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.

  • FPT Industrial ready for Stage V standard
    April 23, 2015
    With the introduction of Stage V/Tier 5 emissions regulations set for 2019-2020, depending on engine power output, FPT Industrial says that it will build upon its SCR-only strategy, remaining one of the few manufacturers not adopting Exhaust Gas Recirculation (EGR) to meet the standard. The Italian firm’s Hi-eSCR after-treatment system, already in use on Stage IV/Tier 4 Final engines, maximises in-engine combustion technology without using EGR. This saves weight, cost and space for the equipment manufacture

    Hitachi Construction Machinery (Europe) (HCME) says its new ZW250-5 wheeled loader being unveiled at bauma is the result of feedback from European customers. The model’s cab is said to be more spacious than models from the previous range, because the heated air-suspension seat can slide further back, providing more leg room. The tilting telescopic pop-up steering column has also been repositioned to create additional space. An air conditioning system has been installed that regulates the temperature inside

  • Sunderland’s sliding bridge slips across the Wear

    Slowly but surely, a 2,500 tonne section of a new bridge deck was eased out from the banks of the River Wear near Sunderland in northern England. It now straddles the water, pointing towards the opposite bank which it will eventually reach after another sliding operation next year likely. The project to build the New Wear Crossing is now half way through with the first half of the steel deck bridge poised mid-river. Completion of the bridge is expected in the spring of 2018. This month, hydraulic jack
