INTERMAT reveal for Scania’s emissions solution

Scania’s integration of XPi high pressure common rail injection and selective catalytic reduction has enabled the Swedish engine maker to meet 2014 Stage IV/Tier 4 Final emissions regulations without a diesel particulate filter. “Developments in metallurgy have helped to strengthen components and lead to increased injection pressures, typically up to 2400 bar,” said Scania industrial engine sales director, Bernt Gustavsson. “A compact DOC is neatly integrated into the SCR system, which saves on space needed

759 Scania’s integration of XPi high pressure common rail injection and selective catalytic reduction has enabled the Swedish engine maker to meet 2014 Stage IV/Tier 4 Final emissions regulations without a diesel particulate filter.

“Developments in metallurgy have helped to strengthen components and lead to increased injection pressures, typically up to 2400 bar,” said Scania industrial engine sales director, Bernt Gustavsson.

“A compact DOC is neatly integrated into the SCR system, which saves on space needed for those with installation constraints.”

Mr Gustavsson says its modular development programme for its inline five- and six-cylinder platforms, plus the 16-litre V8 engine, has enabled refinement of combustion and cooled EGR processes – it is technology that the company has a lot of experience with, and which it employs for its on-road truck and bus applications.

“We may need to add an exhaust brake on engines operating under light duty cycles to raise the exhaust temperature so that SCR remains effective at very light loads,” he said.

    The new Tier 4 Final/Stage IV emission certified engine range from Deutz is being introduced. This complete line-up of diesels meets the coming noise and exhaust emission requirements in Europe and the US and offers capacities from 2.9-16litres. The low emissions performance is achieved using the Deutz DVERT technology, a package of technical solutions that is used in modular form with varying options used to ensure each engine capacity meets the requirements. Compact design and high torque output are claim

    Engines and drivelines technologies have move forward, as could be seen at Conexpo 2014 - Geoff Ascroft reports Solutions for Tier 4 Final emissions regulations dominated Conexpo 2014, with many firms showing off their options of DOC, DPF and SCR after-treatments. Deutz, while staying with an SCR-only solution, took a more unusual approach on its high horsepower V6 12litre and V8 16litre engines. Both get a dual SCR after treatment system to meet Tier 4 Final emission standards. Using a dual SCR system,

    Hatz Diesel will take the wraps off a new engine family at Bauma, with the launch of the H series, a 2.0–litre water-cooled engine family that features Bosch common rail fuel injection with pressures up to 1,800 bar. Producing 56kW (75hp) and 130Nm of torque, the engine meets European Stage IIIB emissions regulations and US Tier 4 Final standards. The engine, a first at this size for the company with liquid-cooling, uses exhaust gas recirculation (EGR) and a diesel oxidation catalyst (DOC) but does without
