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.
