Scania Address SCR Sceptics

Scania announced their new selection of engines at the recent commercial vehicle  exhibition and much to the surprise of SCR sceptics.

Scania now offer EGR technology on less than half of the available range. This is most probably as even though Scania are offering their second generation Scania EGR system, it still requires their XPI technology (extra-high pressure injection) and VGT (variable geometry turbocharger) combined in order to reach the limits as specified within Euro 5.

As proven with tests conducted under trial with both Tesco and Renault, SCR technology has proven to deliver a 4.85% fuel saving between non-SCR equipped Euro 3 and SCR equipped Euro 5 vehicles. Both tests involved running identical routes with identical payloads over an average of 3 months.

This argument is also supported by Scania who still maintain SCR technology on their monster 16 litre V8 engines, designed specifically for long hauls and heavy payloads.

Ultimately AdBlue is used in an approx 3-4% consumption on Euro 4 vehicles and this is increased to 5-6% on Euro 5 vehicles.

Unlike Renault, Iveco and Mercedes’ who’s full HGV range fully supports SCR technology, Scania are considered to be ‘edging their bets’ with SCR sceptics who refuse to embrace new SCR technology.
