Description:PLEASE SEE THE ATTACHMENTS. , Claims:We claim:
1. An oil separator (500) of an internal combustion engine (1000), the oil separator (500) comprising:
a chamber (C) defined with an inlet channel (510) and an outlet channel (520);
a plurality of baffles (B) positioned within the chamber (C) and between the inlet channel (510) and the outlet channel (520), the plurality of baffles (B) are configured to alter a flow direction of a gaseous stream flowing from the inlet channel (510) towards the outlet channel (520); and
an oil separation surface (580) defined at an internal portion of each wall of the chamber (C) and an external portion of each baffle of the plurality of baffles (B), wherein the oil separation surface (580) is configured to absorb oil from the gaseous stream and repel the oil for separating oil from the gaseous stream.

2. The oil separator (500) as claimed in claim 1, wherein the oil separation surface (580) comprises a base (582) and a plurality of bumps (584), wherein the base (582) abuts the internal portion of each wall of the chamber (C) and the outer portion of each baffle of the plurality of baffles (B) and the plurality of bumps (584) are positioned on the base (582) based on pre-defined patterns.

3. The oil separator (500) as claimed in claim 2, wherein the pre-defined patterns of the plurality of bumps (584) are dissimilar from each other based on densities of the plurality of bumps (584).

4. The oil separator (500) as claimed in claim 2, wherein the density of the plurality of bumps (584) defined on the plurality of baffles (B) is greater than density of the plurality of bumps (584) defined on a bottom wall (C1) of the chamber (C).

5. The oil separator (500) as claimed in claim 2, wherein the plurality of bumps (584) of the oil separation surface (580) are made of oleophilic material to absorb oil from the gaseous stream and the base (582) of the oil separation surface (580) is made of oleophobic material to repel the oil of the gaseous stream.

6. The oil separator (500) as claimed in claim 1, wherein the oil separator (500) comprises at least two oil drain holes (540) formed at the bottom wall (C1) of the chamber (C), wherein the at least two oil drain holes (540) are positioned on either side of each baffle of the plurality of baffles (B).

7. The oil separator (500) as claimed in claim 6, wherein the bottom wall (C1) of the chamber (C) is inclined at an angle relative to the side walls (C2, C3) of the chamber (C) to allow the separated oil to flow towards the at least two oil drain holes (540).

8. The oil separator (500) as claimed in claims 2 and 6, wherein the base (582) is defined with a plurality of flow paths (582a), wherein at least one flow path of the plurality of flow paths (582a) is positioned proximal to each oil drain hole of the oil drain holes (540) to aid in flowing the separated oil towards the oil drain hole.

9. The oil separator (500) as claimed in claim 1, wherein the chamber (C) is defined with a plurality of flow regions (530), wherein each flow region defines at least one pair of baffles of the plurality of baffles (B).

10. The oil separator (500) as claimed in claim 9, wherein each baffle defined within at least two flow regions of the plurality of flow regions (530) further defines a first portion and a second portion, wherein the second portion of the baffle extends from the first portion at an angle relative to the first portion of the baffle.

11. The oil separator (500) as claimed in claim 9, wherein each pair of baffles of the plurality of baffles (B) is defined with a gap (G) between two consecutive baffles, wherein the gap (G) of one pair of baffles is dissimilar to the gaps (G) of the other pair of baffles.

12. The oil separator (500) as claimed in claim 1, wherein the plurality of baffles (B) are positioned at two opposite side walls (C2, C3) of the chamber (C), wherein at least one portion of each baffle extending from one side wall (C2) of the chamber (C) is positioned above the at least one portion of the respective baffle extending from the other side wall (C3) of the chamber (C).
