Sliding bearing with lining layer comprising carbon nanostructures

An engine comprising:

• a sliding bearing, the sliding bearing including:
• a backing layer;
• and
• a sintered lining layer disposed on the backing layer that defines an outermost layer of the sliding bearing with respect to the backing layer and has a free surface facing away from the backing layer, the lining layer including carbon nanostructures embedded in a copper-based matrix, wherein the lining layer includes a composition, by weight, in the following proportions:
• 0.1-10% of carbon nanostructures;
• 4-10% of tin;
• 0-1.5% of nickel;
• and
• a balance to 100% of copper and incidental impurities.

A sliding bearing, comprising:

• a backing layer;
• and
• a sintered copper-based composite lining layer that provides an outermost layer with a running surface relative to the backing layer, the running surface defined by a free surface of the lining layer that faces away from the backing layer;
• the lining layer having carbon nanostructures embedded in a copper-based matrix, wherein the lining layer has a composition consisting of:
• 0.1 to 10% wt of carbon nanostructures;
• 4 to 10% wt of tin;
• up to 1.5% wt of nickel;
• and
• a balance to 100% wt of copper and incidental impurities.
