Abstract

PROBLEM TO BE SOLVED: To easily and quickly wipe up lubrication oil spilt in removal of an oil filter by arranging a pair of left and right oil guide parts integrally between an oil filter mounting seat part and an oil pan connecting flange. SOLUTION: On the outside face of a skirt part 2 in a cylinder block 1 in an internal combustion engine, a flange 4 is integrally arranged in the lateral direction, while above the flange 4, a reinforcing lateral rib 5 is arranged integrally. A seat part 7 for an oil filter 6 is integrally arranged above the lateral rib 5, and a pair of left and right oil guide parts 8 extending downward while putting the seat part 7 between them are integrally arranged between the seat part 7 and the lateral rib 5. In addition, a pair of left and right oil guide parts 9 are also arranged integrally so as to extend downward between the lateral rib 5 and the flange 4. In this way, lubrication oil spilt in removal of the oil filter 6 from the seat part 7 can be guided by means of both of the guide parts 8, 9.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure in which an oil filter is mounted on a cylinder block of an internal combustion engine.

[0002]

2. Description of the Related Art Conventionally, an oil filter for lubricating oil in an internal combustion engine is mounted on a side surface of a cylinder block as described in, for example, Japanese Utility Model Laid-Open Publication No. 1-142507. However, if the oil filter is mounted on the side of the cylinder block, the lubricating oil that has spilled when the oil filter was removed will be removed from the skirt at the bottom of the cylinder block. The upper surface of the reinforcing transverse rib integrally provided so as to extend laterally on the side surface and the upper surface of the oil pan joining flange integrally provided so as to extend laterally below the skirt portion. As the oil spreads over a wide area in the horizontal direction, it takes more time and effort to wipe off the oil. Tsu and will not fully be able to wipe off situation there has been a problem that to occur.

An object of the present invention is to provide a cylinder block structure that solves this problem.

[0004]

In order to achieve this technical object, an object of the present invention is to provide an oil pan mounting flange provided on a side surface of a skirt portion provided integrally with a seat portion for mounting an oil filter. A cylinder block integrally provided so as to extend in the lateral direction, a left and right side extending downward with the oil filter mounting seat interposed between the oil filter mounting seat and the oil pan joining flange. A pair of oil guides are provided integrally. "

[0005]

In this configuration, the lubricating oil that has spilled when the oil filter is removed from the oil filter mounting seat is transmitted to the upper surface of the oil pan joining flange by the two oil guides in the lateral direction. You will be guided without flowing. Therefore, according to the present invention, the lubricating oil that spills when the oil filter is removed from the oil filter mounting seat can be reliably prevented from spreading over a wide range in the lateral direction along the upper surface of the oil pan joining flange. Therefore, the operation of wiping off the spilled lubricating oil can be extremely easily performed in a short time, and the wiping operation can be prevented from being impossible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In this figure, reference numeral 1 denotes a cylinder block in an internal combustion engine, and a flange 4 for joining an oil pan 3 to a lower end thereof is integrally formed on an outer surface of a skirt portion 2 at a lower portion thereof so as to extend in a lateral direction. In addition, a reinforcing horizontal rib 5 is integrally provided at a portion above the flange 4 so as to extend in the horizontal direction.

A seat 7 for mounting an oil filter 6 is integrally provided on a portion of the outer surface of the cylinder block 1 higher than the reinforcing horizontal ribs 5. A pair of left and right pair of left and right extending downwards with the oil filter mounting seat 7 interposed therebetween is provided on the outer surface of the cylinder block 1 between the oil filter mounting seat 7 and the reinforcing horizontal rib 5. The first oil guides 8, 8 are integrally provided so that the first oil guides 8, 8 are inclined inward so as to approach each other downward.

Further, a pair of left and right second oil guide portions 9, 9 are also provided between the reinforcing lateral ribs 5 and the oil pan joining flange 4 on the outer surface of the cylinder block 1.
Are integrally provided so as to extend downward from lower end portions of the first oil guide portions 8. In this configuration, the lubricating oil that has spilled when the oil filter 6 is removed from the oil filter mounting seat 7 is transmitted to the upper surface of the reinforcing horizontal rib 5 by the two oil guides 8 and 8 in the lateral direction. The second oil guides 9, 9 guide from the upper surface of the reinforcing horizontal ribs 5 to the upper surface of the oil pan joining flange 4 without flowing in the lateral direction. Thus, the spread of the lubricating oil over a wide range in the lateral direction along the upper surface of the reinforcing horizontal rib 5 and the upper surface of the oil pan joining flange 4 can be reliably reduced.

The second oil guides 9, 9 between the reinforcing horizontal ribs 5 and the oil pan joining flange 4 are directed downward from the lower ends of the first oil guides 8, 8. It is needless to say that the first oil may be provided so as to extend downward from a portion outside the lower ends of the two oil guide portions 8 instead of being provided so as to extend. Guide part 8,
By inclining the second oil guide portion 8 and the second oil guide portions 9 downward so as to approach each other, the spread of the lubricating oil can be kept in a narrower range. By providing the recess 10 in the portion between the first oil guides 8, 8 in the tip of the reinforcing horizontal rib 5, the spilled lubricating oil can be more smoothly applied to the upper surface of the oil pan joining flange 4. I can guide you.
