An Oil Separator Of An Internal Combustion Engine

Abstract: An oil separator (500) of an internal combustion engine (1000), includes a chamber (C), a plurality of flow regions (530), and a plurality of baffles (B). The chamber (C) may be defined with an inlet channel (510) and an outlet channel (520). The plurality of flow regions (530) may be defined within the chamber (C) and fluidly coupled to the inlet channel (510) and the outlet channel (520) to define a flow passage between the inlet channel (510) and the outlet channel (520). The plurality of baffles (B) may be positioned within the plurality of flow regions (530) and extending from opposite sides of the chamber (C). The pair of baffles (B) may be oriented and may be positioned in each flow region such that at least one oil separation zone may be formed within each flow region to separate the oil from a gaseous stream flowing through the plurality of flow regions (530). Figure 4 is representative figure.

Specification

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 flow regions (530) defined within the chamber (C) and fluidly coupled to the inlet channel (510) and the outlet channel (520) to define a flow passage between the inlet channel (510) and the outlet channel (520); and
a plurality of baffles (B) positioned within the plurality of flow regions (530) and extending from opposite sides of the chamber (C), wherein at least one pair of baffles of the plurality of baffles (B) is oriented and positioned in each flow region of the plurality of flow regions (530) such that at least one oil separation zone is formed within each flow region of the plurality of flow regions (530) to separate the oil from a gaseous stream flowing through the plurality of flow regions (530).

2. The oil separator (500) as claimed in claim 1, wherein the plurality of baffles (B) comprises a pair of first baffles (531a, 531b), a pair of second baffles (532a, 532b), and a pair of third baffles (533a, 533b), positioned within a first flow region (531), a second flow region (532), and a third flow region (533) of the plurality of flow regions (530) respectively.

3. The oil separator (500) as claimed in claim 2, wherein each baffle of the pair of first baffles (531a, 531b) is defined with a first portion (P1) and a second portion (P2) extending from the first portion (P1) at an angle relative to the first portion (P1), wherein the second portion (P2) of the pair of first baffles (531a, 531b) extends towards each other.

4. The oil separator (500) as claimed in claim 2, wherein the pair of first baffles (531a, 531b) are positioned such that a first gap (G1) is formed between the pair of first baffles (531a, 531b) and defines a first oil separation zone to separate the oil from the gaseous stream.

5. The oil separator (500) as claimed in claim 2, wherein one baffle of the pair of second baffles (532a, 532b) extends substantially perpendicular from one side wall of the chamber (C) and the other baffle extends at an angle from the other side wall of the chamber (C), wherein a second gap (G2) is formed between the pair of second baffles (532a, 532b) and defines a second oil separation zone to separate the oil from the gaseous stream.

6. The oil separator (500) as claimed in claim 2, wherein each baffle of the pair of third baffles (533a, 533b) is defined with a third portion (P3) and a fourth portion (P4) extending from the third portion (P3) at an angle relative to the third portion (P3), wherein the third portion (P3) of the pair of third baffles (533a, 533b) extends away from each other.

7. The oil separator (500) as claimed in claim 2, wherein the pair of third baffles (533a, 533b) are positioned such that a third gap (G3) is formed between the pair of third baffles (533a, 533b) and defines a third oil separation zone to separate the oil from the gaseous stream.

8. The oil separator (500) as claimed in claim 1, wherein the chamber (C) is defined with a first gap (G1), a second gap (G2), and a third gap (G3), wherein the second gap (G2) is larger than the first gap (G1) and smaller than the third gap (G3).

9. The oil separator (500) as claimed in claim 1, comprising at least two oil drain holes (540) formed at a bottom wall (C1) defined between two side walls (C2, C3) 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).

10. The oil separator (500) as claimed in claim 9, wherein the bottom wall (C1) of the chamber (C) is inclined at an angle relative to the side walls of the chamber (C) to allow the separated oil to flow towards the at least two oil drain holes (540).

11. The oil separator (500) as claimed in claim 1, wherein the chamber (C) and the plurality of baffles (B) are defined with an oil separation surface (580), wherein the oil separation surface (580) comprises a base (582) abutting with internal portions of the chamber (C) and external portions of the baffles (B), and a plurality of bumps (584) positioned on the base (582) based on pre-defined patterns.

12. The oil separator (500) as claimed in claim 11, 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.

13. The oil separator (500) as claimed in claim 1, wherein at least one portion of each baffle extending from one side wall (C1) of the chamber (C) is positioned above the at least one portion of the respective baffle extending from the other side wall (C2) of the chamber (C).
