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.

    Cat’s latest E-series excavator is the 16.7tonne 316E. It replaces the 315D and gets a Cat C4.4 Acert engine to meet EU Stage IIIb emissions. It is the first of three smaller E series being launched by Cat this year. Electric boom regeneration is also available on the new model, and combined with the latest engine technology, gives the company a fuel-saving focus. There is a new cab with lower noise levels – typically a 4dB(a) reduction over its D series predecessor – and improved comfort and visibility too
