Volvo unveils Euro 6 engine

Volvo has unveiled a Euro 6 engine which it says is optimised for fast fuel-efficient transport on good roads.

The D13 460 hp engine, which will be delivered in Spring 2013, is based on Volvo’s existing Euro 5 engine and will go into the FH series of artics and rigids.

It is an in-line six cylinder engine with unit injectors and catalytic exhaust treatment (SCR). To meet the new emission requirements, exhaust gas recirculation (EGR) is also used, as well as a diesel particulate filter (DPF) – systems that Volvo has been using for several years in the US and Japan.

Compared with Euro 5, oxides of nitrogen emissions have been cut by 77 per cent and particulate emissions have been halved to 0.01 g/kWh.

Unlike conventional EGR systems that cool down the recirculated exhaust gases to lower engine temperature and thus reduce nitrogen oxide emissions, Volvo’s Euro-6 engine’s EGR system is virtually inactive during highway cruising, so it does not impact fuel consumption during such operations.

Mats Franzén, manager of engine strategy and planning, said: “It is currently difficult to determine how much demand there will be, but by offering our most popular engine in a Euro-6 configuration, we meet the needs of a large proportion of our customers. The rest of the Euro-6 engine range will be launched well before the requirements become obligatory on 1st January 2014.”
