Objective
Reciprocating engine emissions are of increasing public concern, eg solid exhaust particulates from diesel engines are deemed to be carcinogens. Up to 60 % of the particulates emitted originate from uncontrolled combustion of lube oil. To reduce this significantly a new philosophy of engine design, "the clean car", is required.
Much reduced or no lubrication of valve train components, such as rocker arms, valve giodes and valve seats is now proposed. There are presently no materials available which could reliably operate in the severe tribological conditions at temperature up to 600 degree C.
The objective of this project is to develop solid state lubricant/hard ceramic phase/strong metallic matrix composite materials by powder metallurgy (PM) methods.
Conventional or modified PM techniques will be applied to newly-developed fine particle powders including special agglomeration techniques. Up to 15 vol % solid state lubricant dispersed in a high strength matrix is aimed for.
The research programme is formulated jointly between a powder producer, three PM part manufacturers, a diesel engine/truck producer and an academic research group. The aim is, in the long term engine test, to achieve a reduction of particulate emissions by 0.03 gm/HP.hr for the whole useful engine life of 500.000 km.
According to diesel experts such a value cannot be attained solely by reducing the piston-cylinder running clearances, increasing tightness of valve stern seals and improvements in engine management systems, but necessitates reduction or elimination of valve train lubrication, which in turn requires the development of new composite materials for the components.
