Scania’s versatile engine design
759 Scania claims that field test of its latest engine designs show that the units meet all the emission and noise requirements of Tier 4 Final/Stage IV. The tests are said to have highlighted the robust nature of these engines in an array of challenging, off-highway working cycles and applications. The company has tested the engines in applications such as excavators, wheel loaders, crushers and dump trucks. Scania’s technology to minimise emissions includes key features as extra-high-pressure injection (Scania XPI), exhaust gas recirculation (EGR) and selective catalytic reduction (SCR). A sophisticated control system optimises a large number of engine parameters, with different modes that combine the amount of fuel, injection timing and settings of the variable geometry turbocharger. This controller ensures that the mix of air and recirculated exhaust is combined with the correct amount of urea solution AdBlue.

For the EGR system the controller balances the ratio between the air and recirculated to minimise particulate emissions. It also prevents the engine from running too cold as this will reduce SCR efficiency and increase NOx as a result. The company claims that the new engine management system to switch very rapidly between the different operating modes, while also helping to minimise fuel consumption.

  • No DPF for Doosan’s Tier 4 Final compact engine range
    March 7, 2014
    Doosan Infracore’s engine business group used Conexpo to launch a new range of compact diesel engines that meet Tier 4 Final emissions legislation and avoid using a diesel particulate filter (DPF). Called the D18, D24 and D34, the three-model range spans an output range of 20-90kW and offers engine capacities of 1.8, 2.4 and 3.4litres as it targets OEM skid steer loader, compact excavator, air compressor and generator businesses. The non-DPF solution means the two smaller models need only a diesel oxidati

    John Deere Power Systems used bauma to complete its engine line-up for Tier 4 Final/Stage IV emissions regulations. This included the arrival of the PowerTechTM PWL 4.5L engine, which meets emissions regulations without a diesel particulate filter (DPF). Spanning outputs from 63-104kW, this four-cylinder, 4.5litre engine offers reduced cost and improves engine packaging by eliminating the DPF, said Deere. However, the engine uses selective catalytic reduction (SCR), a diesel oxidation catalyst (DOC) and coo

  • Increased versatility is offered by the new Doosan wheeled excavators
    January 6, 2017
    Aimed at the 14tonne and 16tonne classes, the new Doosan DX140W-3 and DX160W-3 wheeled excavators are said to offer major performance gains over the models being replaced. As with the firm’s new crawler excavators, new cabs provide a more comfortable working environment, with improved controls and ergonomics and in-cab noise levels that are reduced by 5dBA. Both machines are powered by the proven Doosan DL06KB diesel, which delivers a 2% increase in power to 102kW and a 12% increase in torque over the previ
