Abstract

The present disclosure generally relates to a locomotive diesel engine and, more particularly, to a heavy particle oil separator splash shield. Specifically, provided is a system and method for reducing exhaust particulate emissions. The present shield prevents large oil droplets in close proximity to the oil separator from easily entering the element, thus preventing less saturation of the oil separator and increasing the efficiency of the oil separator. As a result, environmental pollution is reduced.

Claims (9)

1. An oil splash shield for minimizing transfer of heavy particle oil droplets from a cam shaft drive gear of a crankcase to an oil separator in a locomotive diesel engine, wherein the engine includes a turbocharger having a mounting flange defining an opening therein leading to the oil separator, wherein vapors flow from the crankcase to the oil separator via the opening, wherein the oil separator is configured to separate particulate matter and oil from the vapors emitted from the crankcase, wherein said crankcase includes a crankcase housing, said oil splash shield comprising:

a member situated adjacent to the opening between the oil separator and the crankcase of the engine, said member being selectively sized and shaped to extend near a portion of the opening to deflect heavy oil droplets, said member being positioned such that a clearance is defined between the member and the opening for allowing vapors to flow from the crankcase to the oil separator, and

a mounting element for affixing the shield to the crankcase housing, wherein the mounting element is situated in relation to the member such that affixation of the mounting element to the crankcase housing causes the member to extend away from the crankcase and towards the opening.

2. The oil splash shield of claim 1 wherein the member is U-shaped with rounded edges.

3. The oil splash shield of claim 1 wherein the mounting element defines a plurality of apertures for receiving a fastening mechanism for affixing the shield to the crankcase housing.

4. The oil splash shield of claim 3 wherein the fastening mechanism is a bolt.

5. The oil splash shield of claim 1 wherein the mounting element forms an L-shape to provide support for the member.

6. The oil splash shield of claim 1 , wherein the mounting element includes a plurality of support members for maintaining the rigidity of the shield.

7. The oil splash shield of claim 6 wherein the support members are in the form of support triangles.
