Abstract | Engine oil may pool in various locations in the cylinder head near the valves and underneath the camshaft. Rather than directly conducting the oil to the oil return passages, the oil is conducted to a surface proximate the exhaust ducts before being conducted to the oil return passage so that the oil is readily warmed up during a cold start by the contact with a surface in the cylinder head proximate exhaust ducts. 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. |
