ENGINE LUBRICATION SYSTEM

摘要

Engine lubrication systems and methods of manufacturing and implementing engine lubrication systems and methods. In particular embodiments, an engine system includes an internal combustion engine lubrication system that utilizes a stacked configuration of a through-bolted engine to pattern around through-bolts and utilizes substantially hollow bulkheads to define a central high-pressure lubrication reservoir that minimizes lube system pressure while maintaining pressure at the extremities of the lubrication circuit. Available space is utilized within the bulkheads to provide a lubrication drainage restriction for reducing lubrication losses at engine shut-down.

主权项

1. An internal combustion engine, comprising:
a base including an upper surface; a cylinder block mounted to the upper surface of the base via a lower surface of the cylinder block, the cylinder block including a reservoir disposed therein; a cylinder head coupled to cylinder block; a cam carrier coupled to the cylinder head, such that the cylinder head is positioned between the cylinder block and the cam carrier, wherein the base, the cylinder block, the cylinder head, and the cam carrier form a plurality of through-bolt openings, each through-bolt opening in the plurality of through bolt openings extending from the base to the cam carrier through the cylinder block and the cylinder head, and a plurality of lubrication circuits positioned in at least one of the base, the cylinder block, the cylinder head and the cam carrier, the plurality of lubrication circuits fluidly coupled to the reservoir, the plurality of lubrication circuits fluidly decoupled from the plurality of through bolt openings.
