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.

    Bobcat’s M Series mini excavators have moved to the Tier 4 emissions standard without the need for a diesel particulate filter (DPF). The E42, E45, E50 and E55 mid-size mini excavators use an ultra-low particulate combustion process engine, which in the two heavier models offers up to 12% more torque than previous models of a similar size. The excavators feature a cold weather protection system that recognises when engine temperatures are low and limits the maximum output to prevent premature component fail
