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.

    Like its fellow new 9A series hydraulic excavators with engines above 130kW, the engine on the Robex R380NLC-9A hydraulic crawler excavator from Hyundai Heavy Industries (HI) comes with an EGR and diesel particulate filter (DPF). The DPF is said to be automatically or manually regenerated, ensuring compliance with all NOx and PM values. According to Hyundai HI, DPF filters only need to be cleaned after 5,000 to 6,000 hours in operation.
