20110056456 | CYLINDER HEAD WITH OIL RETURN - Engine oil may pool in various locations in the cylinder head near the valves and underneath the camshaft.

The provision of such a surface proximate exhaust ducts is facilitated by the integrated exhaust manifold design in which the exhaust ducts are merged prior to exiting the cylinder head. By rapidly heating the oil, the oil's viscosity decreases, thereby reducing friction and improving fuel efficiency. | 03-10-2011 |
