Abstract

Methods and systems are provided for an internal combustion engine having an oil circuit. In one example, a system may include a rising oil line from a block to a cylinder head of an engine; a main oil line in the head; and an oil siphon system including a reservoir positioned between, and having at least one portion at a lower elevation than both, a section the rising line and a section of the main oil line so that oil flows into, and remains in, the reservoir when the engine is shut-off. In this way, the design of the oil circuit may be used to improve oil supply to engine components while minimizing delays in oil supply during engine startup.
