Definitions

  • the present invention relates to a structure for pouring lubricant oil into an internal combustion engine.
  • a structure including a pouring pipe and an outer wall is known as a structure for pouring lubricant oil into an internal combustion engine.
  • the pouring pipe projects upward from a head cover body, which is a main portion of a cylinder head cover, at an end of the head cover body in the direction in which the cylinders of the engine are arranged.
  • the pouring pipe has a pouring port for lubricant oil at the upper end.
  • a filler cap is detachably attached to the upper end of the pouring pipe with a gasket in between such that the pouring port is selectively closed and opened. The filler cap is attached by being threaded onto the pouring pipe.
  • the outer wall of the conventional lubricant oil pouring structure is arranged between the outer circumferential surface of the pouring pipe and the head cover body.
  • the outer wall surrounds at least part in the circumferential direction of the outer circumferential surface of the pouring pipe with a hollow portion in between.
  • the outer wall enhances the rigidity of the pouring pipe.
  • a lower end of the pouring pipe and a lower end of the hollow portion are both open to the internal space of the head cover body.
  • a typical lubricant oil pouring structure for an internal combustion engine is demanded to, at the time of replacement of lubricant oil, ensure that the amount of the lubricant oil that can be poured into the engine through the pouring pipe is great and that pouring efficiency is high. Since other components of the engine are arranged in the vicinity of the cylinder head cover, there is limitation to increase of the diameter of the pouring pipe to avoid interference with these components. This problem occurs also in the lubricant oil pouring structure described in Japanese Laid-Open Patent Publication No. JP 2010 059936 A . However, the publication does not include consideration as to a structure for meeting the above-described demand for the high pouring efficiency.
  • a lubricant oil pouring structure for an internal combustion engine capable of improving lubricant oil pouring efficiency while enhancing the rigidity of the pouring pipe.
  • a lubricant oil pouring structure for an internal combustion engine.
  • the lubricant oil pouring structure is employed in a cylinder head cover including a head cover body and includes a pouring pipe and an outer wall.
  • the pouring pipe projects upward from the head cover body and has a pouring port for lubricant oil at an upper end of the pouring pipe.
  • a filler cap is detachably attached to the pouring pipe from above such that the pouring port is selectively closed and opened.
  • the outer wall is arranged between an outer circumferential surface of the pouring pipe and the head cover body and surrounds at least part in a circumferential direction of the outer circumferential surface of the pouring pipe with a hollow portion in between. At least part of a lower end of the pouring pipe and at least part of a lower end of the hollow portion are open to an internal space of the head cover body.
  • a communicating portion which allows communication between an internal space of the pouring pipe and the hollow portion, is formed in at least a lower portion of a section of the pouring pipe that is surrounded by the outer wall.
  • the pouring pipe and the head cover body are joined to each other by the outer wall. This enhances the rigidity of the pouring pipe. As a result, even when vibration of the engine is transmitted to the pouring pipe, the pouring pipe is unlikely to vibrate.
  • At least part of the lower end of the pouring pipe is open to the internal space of the head cover body.
  • the communicating portion in at least the lower portion of the section of the pouring pipe surrounded by the outer wall, communication between the internal space of the pouring pipe and the hollow portion is allowed. At least part of the lower end of the hollow portion is open to the internal space of the head cover body.
  • the amount of lubricant oil that can be poured into the engine through the pouring pipe is increased by the amount corresponding to the amount of the lubricant oil that passes through the open portion of the lower end of the hollow portion.
  • the pouring efficiency is thus improved.
  • the above-described lubricant oil pouring structure for an internal combustion engine is capable of improving lubricant oil pouring efficiency while enhancing the rigidity of the pouring pipe.
  • An internal combustion engine 10 illustrated in Figs. 3 and 6 has multiple cylinders arranged in a row.
  • a cylinder head 11 of the engine 10 incorporates a valve operating mechanism that operates an intake valve and an exhaust valve of each cylinder.
  • the intake valves and the exhaust valves are operated by rotating an intake-exhaust camshaft, which extends in the cylinder arrangement direction.
  • a rotation transmitting member 12, such as a sprocket is arranged at an end of the intake-exhaust camshaft in the cylinder arrangement direction. Rotation of the crankshaft is transmitted to the intake-exhaust camshaft through the timing chain, the rotation transmitting member 12, and the like, thus driving the intake valves and the exhaust valves.
  • a cylinder head cover 14 is arranged on the cylinder head 11.
  • the cylinder head cover 14 includes a head cover body 15.
  • An end 15a of the head cover body 15 on the same side as the rotation transmitting member 12 in the cylinder arrangement direction is formed wider than other sections in the cylinder arrangement direction.
  • the rotation transmitting member 12 and the like are arranged in the end 15a (see Fig. 2 ).
  • a flange 16 is formed in a lower-end peripheral edge of the head cover body 15.
  • the flange 16 is arranged on the cylinder head 11 with a gasket 13 in between (see Fig. 6 ).
  • the flange 16 has fastening portions 17 at multiple positions. Each fastening portion 17 has a bolt insertion hole 17a. Bolts are inserted through the bolt insertion holes 17a, thus fastening the head cover body 15 to the cylinder head 11.
  • the number of the mounting holes 20 is equal to the number of the cylinders.
  • the arrangement direction of the mounting holes 20 thus coincide with the cylinder arrangement direction.
  • a flat portion 21, a first stepped portion 22, and a second stepped portion 23 are formed at the end 15a of the head cover body 15.
  • the first stepped portion 22 is formed at a position lower than the flat portion 21 and separated from the flat portion 21.
  • the second stepped portion 23 is formed at a position even lower than the first stepped portion 22 between the flat portion 21 and the first stepped portion 22.
  • the pouring pipe 25 is formed as part of the cylinder head cover 14.
  • the upper end of the pouring pipe 25 is arranged at a position higher than the flat portion 21.
  • the pouring pipe 25 includes a large diameter portion 26, an upper tapered portion 27, a small diameter portion 28, a lower tapered portion 29, and a bottom portion 31 sequentially in this order from the upper side to the lower side.
  • the large diameter portion 26 is located in an upper section of the pouring pipe 25 and is shaped like a circular tube.
  • the small diameter portion 28 is shaped like a circular tube with a diameter slightly smaller than the diameter of the large diameter portion 26.
  • the upper tapered portion 27 is located between the large diameter portion 26 and the small diameter portion 28 and has a diameter that becomes smaller toward the lower end.
  • the lower tapered portion 29 is located between the small diameter portion 28 and the bottom portion 31 and has a diameter that becomes smaller toward the lower end.
  • the upper end of the internal space of the large diameter portion 26 is open, and the opening configures a pouring port 32.
  • a filler cap 35 is detachably attached to the pouring pipe 25 from above. More specifically, the filler cap 35 includes a head portion 36 and a shaft portion 37, which has a diameter smaller than that of the head portion 36 and projects downward from the head portion 36.
  • An external threaded portion 38 is formed on the outer circumferential surface of the shaft portion 37.
  • An internal threaded portion 33 is formed on the inner circumferential surface of the large diameter portion 26 of the pouring pipe 25.
  • the external threaded portion 38 is threaded onto the internal threaded portion 33. This fastens the filler cap 35 to the pouring pipe 25, thus closing the pouring port 32.
  • the reactive force produced by depressing the gasket 34 ensures the axial force (the fastening force) of the filler cap 35.
  • Part in the radial direction of the pouring pipe 25 projects from the end 15a of the head cover body 15 in the cylinder arrangement direction. In the present embodiment, substantially half in the radial direction of the pouring pipe 25 projects from the end 15a.
  • An outer wall 41 is arranged between the outer circumferential surface of the large diameter portion 26 of the pouring pipe 25 and the second stepped portion 23 of the head cover body 15.
  • the outer wall 41 surrounds at least part in the circumferential direction of the outer circumferential surface of the pouring pipe 25 with a hollow portion 44 in between.
  • the outer wall 41 is arranged in the part of the pouring pipe 25 that does not project from the end 15a of the head cover body 15.
  • the lower end of the outer wall 41 is continuous with the second stepped portion 23.
  • the upper end of the outer wall 41 is continuous with the upper end of the large diameter portion 26.
  • the outer wall 41 includes a curved portion 42 and a projecting portion 43, which is adjacent to the curved portion 42 in the circumferential direction of the pouring pipe 25.
  • the curved portion 42 has a curved surface 42a, which is curved in the circumferential direction and extends in the vertical direction to form part of a cylindrical shape.
  • the projecting portion 43 has two flat surfaces 43a, which are adjacent to each other in the circumferential direction and each extend in the vertical direction. The projecting portion 43 projects outward in the radial direction of the pouring pipe 25.
  • At least part of the lower end of the hollow portion 44 is open to an internal space 47 of the head cover body 15.
  • a bottom portion 31, which forms part of the lower end of the pouring pipe 25, is open to the internal space 47 of the head cover body 15 in the part that does not project from the end 15a of the head cover body 15.
  • at least part of the lower end of the pouring pipe 25 is open to the internal space 47.
  • This part is referred to as an open portion 31a of the bottom portion 31.
  • a communicating portion 45 which allows communication between an internal space 46 of the pouring pipe 25 and the hollow portion 44, is formed in at least a lower part of the section of the pouring pipe 25 surrounded by the outer wall 41.
  • the communicating portion 45 is formed by cutting out a section of the pouring pipe 25 corresponding to the small diameter portion 28 and the lower tapered portion 29 that does not project from the end 15a of the head cover body 15.
  • the communicating portion 45 is formed to be continuous with the open portion 31a of the bottom portion 31 of the pouring pipe 25.
  • the upper end of the communicating portion 45 is located at the boundary between the upper tapered portion 27 and the small diameter portion 28.
  • the boundary is at the highest or substantially highest position at which sufficient strength of the internal threaded portion 33 is ensured.
  • the open portion 31a and the communicating portion 45 configure an outflow port of the pouring pipe 25 for the lubricant oil O1.
  • a guide portion 19a is formed in part of the baffle plate 19.
  • the guide portion 19a guides lubricant oil O2, which is splashed by the rotation transmitting member 12 as the valve operating mechanism of the engine 10 operates, to the pouring port 32 of the pouring pipe 25.
  • the guide portion 19a is located below the communicating portion 45 of the pouring pipe 25 (see Fig. 3 ).
  • the guide portion 19a is arranged to be inclined with respect to the horizontal direction such that a downstream section in the splashing direction of the lubricant oil O2 is closer to the pouring pipe 25 (is higher) than an upstream section.
  • the outer circumferential surface of the pouring pipe 25 and the second stepped portion 23 of the head cover body 15 are joined to each other by the outer wall 41, which enhances the rigidity of the pouring pipe 25.
  • the outer wall 41 projects upward from the second stepped portion 23 and the upper end of the outer wall 41 is continuous with the upper end of the large diameter portion 26 of the pouring pipe 25.
  • the outer wall 41 which is arranged substantially along the pouring pipe 25 in the height direction, enhances the rigidity of the pouring pipe 25 in a large range in the height direction.
  • the outer wall 41 includes the projecting portion 43, which has the two flat surfaces 43a adjacent to each other in the circumferential direction, as well as the curved portion 42 having the curved surface 42a. This effectively enhances the rigidity of the pouring pipe 25 compared with a case in which the outer wall 41 is configured simply by the curved portion 42.
  • the ribs 24, which are arranged in the first stepped portion 22 in the lower part of the pouring pipe 25, are continuous with the bottom portion 31, thus enhancing the rigidity of the pouring pipe 25.
  • the pouring pipe 25 Since the rigidity of the pouring pipe 25 is enhanced in the above-described manners, the pouring pipe 25 is unlikely to vibrate even when vibration of the engine 10 is transmitted to the pouring pipe 25. As a result, even if the heat of the engine 10 fatigues the gasket 34, as has been described, the filler cap 35 is unlikely to turn in the loosening direction.
  • the filler cap 35 is detached from the pouring pipe 25 to open the pouring port 32, as shown in Fig. 4 , with the engine 10 in a stopped state. Then, as represented by the long dashed double-short dashed lines in Fig. 3 , the lubricant oil O1 is poured from the pouring port 32.
  • the open portion 31a of the lower end (the bottom portion 31) of the pouring pipe 25 is open to the internal space 47 of the head cover body 15.
  • some of the lubricant oil O1 poured from the pouring port 32 flows down in the pouring pipe 25 and is supplied to the interior of the engine 10 from the open portion 31a of the bottom portion 31.
  • the lower end of the pouring pipe 25 is closed by the bottom portion 31 particularly in the part of the pouring pipe 25 that projects from the end 15a of the head cover body 15 in the cylinder arrangement direction. This reduces the size of the open portion 31a with respect to the internal space 47 of the head cover body 15 in the lower end of the pouring pipe 25. Without the communicating portion 45, the outflow port of the pouring pipe 25 would be configured simply by the open portion 31a. This would cause an insufficient outflow efficiency of the lubricant oil. In this case, the amount of the lubricant oil O1 that can be poured into the pouring pipe 25 from the pouring port 32 would be small, resulting in a poor pouring efficiency.
  • the communicating portion 45 is arranged in at least the lower portion of the section of the pouring pipe 25 surrounded by the outer wall 41, the internal space 46 of the pouring pipe 25 and the hollow portion 44 are allowed to communicate with each other. At least part of the lower end of the hollow portion 44 is open to the internal space 47 of the head cover body 15.
  • This increases the amount of the lubricant oil O1 that can be poured into the engine 10 through the pouring pipe 25 by the amount corresponding to the amount of the lubricant oil O1 passing through the open portion 44a of the hollow portion 44, thus improving the pouring efficiency.
  • the communicating portion 45 is formed to be continuous with the open portion 31a of the bottom portion 31 of the pouring pipe 25. This efficiently increases the cross-sectional area of the outflow port of the pouring pipe 25 for the lubricant oil O1 compared with a case in which the communicating portion 45 is separated from the open portion 31a.
  • the upper end of the communicating portion 45 is arranged at the highest or substantially highest position at which sufficient strength of the internal threaded portion 33 is ensured. This arrangement is also effective to efficiently increase the cross-sectional area of the outflow port of the pouring pipe 25.
  • substantially half in the radial direction of the pouring pipe 25 projects from the end 15a of the head cover body 15.
  • the size of the open portion 31a with respect to the internal space 47 of the head cover body 15 is small in the lower end of the pouring pipe 25.
  • the communicating portion 45 as has been described, the cross-sectional area of the outflow port of the pouring pipe 25 is efficiently increased to reduce the influence on the pouring amount of the lubricant oil O1.
  • overflow of some of the lubricant oil O1, which has been poured, from the pouring port 32 is restrained.
  • the pouring pipe is surrounded by the outer wall with the hollow portion in between.
  • the lower end of the pouring pipe and the lower end of the hollow portion are both open to the internal space of the head cover body.
  • the pouring pipe lacks the part corresponding to the communicating portion 45 of the present embodiment.
  • the hollow portion restrains entry of the lubricant oil splashed in the head cover into the interior of the pouring pipe.
  • the pouring pipe thus must be extended to the lowest possible point without providing a portion like the communicating portion 45 of the present embodiment.
  • the device of the publication cannot exert an effect of improving the pouring efficiency, unlike the present embodiment.
  • the cloudy lubricant oil is scraped off by causing the splashed lubricant oil O2 striking the backside of the shaft portion 37, as has been described.
  • the cloudy lubricant oil is thus unlikely to remain on the backside of the shaft portion 37. As a result, the erroneous determination of failure is unlikely to be made at the time of inspection.
  • the hollow portion 44 exerts a heat insulating effect to make it unlikely that the heat in the pouring pipe 25 will be released to the atmospheric air.
  • the lubricant oil is thus unlikely to become cloudy, and deterioration of the lubricant oil is restrained.
  • the pouring pipe 25 projects upward and the filler cap 35 is mounted at the upper end of the pouring pipe 25. This facilitates work for attachment/detachment of the filler cap 35 and improves the work efficiency.
  • the pouring port 32 which is arranged at a high position, facilitates the work for pouring the lubricant oil O1.
  • the head cover body 15 which is made of plastic
  • the outer wall 41 is molded around the pouring pipe 25, which has the internal threaded portion 33, with the hollow portion 44 in between. Therefore, by arranging a cooling pipe in part of the mold that molds the hollow portion 44, the internal threaded portion 33 is efficiently cooled. Sink marks or the like are thus unlikely to be caused.
  • the pouring pipe 25 may be arranged at such a position in the head cover body 15 that the pouring pipe 25 does not project from the end 15a on one side in the cylinder arrangement direction of the engine. In this case, a large portion (including the entirety) of the lower end of the pouring pipe 25 may be open to the internal space 47 of the head cover body 15.
  • the pouring pipe 25 may be arranged at such a position that the pouring pipe 25 projects from the end 15a by an amount smaller or greater than that of the present embodiment.
  • the outer circumferential surface of the pouring pipe 25 as a whole in the circumferential direction may be surrounded by the outer wall 41 with the hollow portion 44 in between.
  • a large portion (including the entirety) of the lower end of the hollow portion 44 may be open to the internal space 47 of the head cover body 15.
  • the pouring pipe 25 may project upward from the head cover body 15 with part of the pouring pipe 25 projecting from a corner of the end 15a.
  • the position of the upper end of the communicating portion 45 may be changed to a position lower than that in the above illustrated embodiment.
  • the communicating portion 45 may be formed in part of the pouring pipe 25 separated from the open portion 31a of the bottom portion 31.
  • the communicating portions 45 may be arranged at multiple circumferential positions of the pouring pipe 25.
  • a pouring pipe (25) projects upward from a head cover body (15), which is a main portion of a cylinder head cover (14), and has a pouring port (32) for lubricant oil (O1) at the upper end of the pouring pipe (25).
  • a filler cap (35) is detachably attached to the pouring pipe (25) from above such that the pouring port (32) is selectively closed and opened.
  • An outer wall (41) is arranged between an outer circumferential surface of the pouring pipe (25) and the head cover body (15). The outer wall (41) surrounds at least part in the circumferential direction of the outer circumferential surface of the pouring pipe (25) with a hollow portion (44) in between.
  • At least part of a lower end of the pouring pipe (25) and at least part of a lower end of the hollow portion (44) are open to an internal space (47) of the head cover body (15).
  • a communicating portion (45), which allows communication between an internal space (46) of the pouring pipe (25) and the hollow portion (44), is formed in at least a lower portion of a section of the pouring pipe (25) that is surrounded by the outer wall (41).
