Oil sump improves fuel economy, reduces noise and emissions 29 June 2012

An oil sump moulded from DuPont Zytel nylon resin is helping Scania to beat noise, emissions and weight challenges.

The lightweight oil sump is among a range of technical solutions incorporated by Scania in its new 440 and 480bhp, 13-litre Euro 6-compliant engines.

The sump was produced in Sweden by the Plastal Group – which supplies engineered plastics to the automotive industry – with the material, design and processing support of DuPont, plus prototyping expertise from Idé-Pro of Skive, Denmark.

The sump is moulded from a heat-stabilised, glass-fibre reinforced grade of Zytel 66 nylon, and has resulted in a more than 50% weight – or 6kg, versus its aluminium predecessor.

The Zytel used is a 35% glass fibre reinforced, lubricated polyamide 66, which is a material of choice for harsh, under-the-hood applications involving high temperatures and oil.
