Embodiment Construction

[0015] figure 1 An example embodiment of machine 10 is shown. For example, if figure 1 As shown, machine 10 may be a locomotive designed to pull rail vehicles. Machine 10 may have a platform 12 . A plurality of wheels 14 may be configured to support the platform 12 . Wheels 14 may also be configured to engage rails 16 . Each wheel 14 may have a traction motor (not shown) associated therewith. Traction motors may drive wheels 14 to propel machine 10 in a forward or rearward direction.

[0016] Machine 10 may have an engine 18 mounted on platform 12 . Engine 18 may be configured to propel machine 10 . For example, engine 18 may be configured to drive one or more generators (not shown), which may generate electricity to drive one or more traction motors. Although figure 1 One engine 18 is shown, it is envisioned that the machine 10 may have more than one engine 18 . in such as figure 1 In the example embodiment shown, engine 18 may be longitudinally aligned on platform...

Abstract

A prelubrication and rewetting system for a machine is disclosed. Specifically, a lubrication system for an engine is disclosed. The lubrication system may have an oil pump configured to lubricate the engine. The lubrication system may also have a valve configured to direct oil from the oil pump to a fuel pump associated with the engine. The lubrication system may also have a controller. The controller may be configured to determine an operating speed of the engine. The controller may also be configured to adjust the valve to selectively direct oil to the fuel pump based on the speed of operation.

Description

technical field [0001] The present invention relates generally to lubrication systems, and more particularly to prelubrication and rewetting systems for machines. Background technique [0002] An internal combustion engine includes a number of metallic components that move in close proximity relative to each other. To reduce friction between moving parts, engines typically include a lubrication system that supplies oil to lubricate the moving parts. Lubrication systems typically include an engine-driven oil pump that draws oil from a sump and circulates the oil through the engine. [0003] However, when the engine remains inactive for a long period of time, the oil in the engine drains into the sump under the force of gravity. Therefore, to prevent damage to the moving parts of the engine, it is necessary to pre-lubricate the engine before starting it. Typically, an auxiliary oil pump driven by an electric motor draws and circulates oil from the sump to pre-lubricate the ...
