Engine oil return structure of automobile engine
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engine oil return structure of an engine mounted on an automobile, and more particularly to an engine oil return structure of an automobile engine in which coral and metal bearing troubles of an engine oil are suppressed.
As is well known, the engine of an automobile is a power source that drives wheels through a power transmission path by converting thermal energy when fuel is combusted into mechanical energy, and each perturbation part of the engine generates large friction. Engine oil is supplied to each perturbation unit.
When the engine is driven, the oil pump connected to the crankshaft is interlocked so that the oil stored in the oil pan is pumped along the oil supply line and supplied to each perturbation part, and then returned to the oil pan. FIG. 1 shows an engine oil according to the prior art. As an example of the return structure, according to this, the oil return hole (1b) is formed in the cylinder block 1 in the state of the material, it is formed to communicate with the inside of the cylinder block (1), along the oil return hole (1b) The engine oil 4 to be flowed is returned to the oil pan 23 provided at the lower end of the cylinder block 1 along the guide 1c of the cylinder block 1.
Figure 2 is another example of the engine oil return structure according to the prior art, according to this, the oil return hole (11b) is formed in the cylinder block 11 by the hole processing, it is formed to communicate with the inside of the cylinder block (1) The engine oil 4 flowing along the oil return hole 11b is returned to the oil pan 23 provided at the lower end of the cylinder block 1.
Meanwhile, reference numerals 1a and 11a of FIGS. 1 and 2 are blow-by-gas holes formed in the cylinder blocks 1 and 11.
However, when the oil return hole 1b is formed in the cylinder block 1 in the state of the material, foreign substances such as sand adhered to the oil return hole 1b are attached when the cylinder block 1 is cast. The engine oil 4 flowing along the hole 1b contains a large amount of foreign matter. The engine oil 4 introduced into the cylinder block 1 has a power conversion mechanism 2 coupled to a connecting rod and a crankshaft. Since it is returned to the oil pan (4) after falling to the mechanism, foreign matters are attached to the crankshaft metal bearing and the connecting rod metal bearing, causing trouble, and also causing oxidation of the engine oil.
In addition, when the oil return hole (11b) is formed in the cylinder block 11 by hole processing, the production cost according to the hole processing is greatly improved, foreign matter such as sand attached to the oil return hole (1b) during the casting Even if not, since the engine oil 4 finally introduced into the cylinder block 11 through the oil return hole 11b contains a lot of other foreign matters, trouble caused by foreign matters may occur in the crankshaft metal bearing and the connecting rod metal bearing. In addition to being present, there is a problem that the oxidation of engine oil is promoted.
Accordingly, the present invention has been invented to solve the problems described above, and an object thereof is to provide an engine oil return structure of an automobile engine to suppress oxidation of engine oil and troubles of metal bearings.
1 is an example of an engine oil return structure according to the prior art;
Figure 2 is another example of the engine oil return structure according to the prior art,
3 is a view showing an engine oil return structure according to the present invention.
* Description of the symbols for the main parts of the drawings *
2: power conversion mechanism 21: cylinder block
21a: blow-by gas hole 21b: oil return hole
22: oil return member 23: oil pan
23a: oil return inlet 24: engine oil
25: gasket 26: oil return cover
The present invention for achieving the above object, the oil return hole for inducing the engine oil returned to the outside in the cylinder block is formed in the material state, the oil return is formed in the oil return inlet penetrated to the outside, the oil The return hole and the oil return inlet communicate with each other by the oil return member so that the returned engine oil is prevented from sticking to the power conversion mechanism mounted inside the cylinder block.
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
3 is a view illustrating an engine oil return structure according to the present invention, and accordingly, an oil pan at a lower end of a cylinder block 21 in which a blow-by gas hole 21a and an oil return hole 21b are formed in a material state. (23) is installed, the power switching mechanism (2) is built in the interior of the cylinder block 21, the oil return hole (21b) is formed to guide the return oil pan 24 to the outside, An oil return inlet 23a penetrated outside is formed in the oil pan 23, and the oil return hole 21b and the oil return inlet 23a communicate with each other by the oil return member 22. 21b and the oil return member 22 are connected to each other via the oil return cover 26, and a gasket 25 is inserted between the oil return cover 26 and the fastening portion of the cylinder block 1.
According to the present invention, since the oil pan 24 flowing along the oil return hole 21b directly flows into the oil pan 23 through the oil return member 22, the oil pan 24 is mounted inside the cylinder block 21. The engine oil 24 returned to the power switching mechanism 2 does not stick.
According to the present invention as described above, since the engine oil return line is changed and the engine oil returned to the power conversion mechanism mounted inside the cylinder block is not adhered, oxidation of the engine oil and trouble of metal bearings are suppressed. As a result, hole processing, which has been mentioned in the related art, becomes unnecessary, thereby reducing the production cost.
What has been described above is only one embodiment of the present invention, and the present invention is not limited to the above-described embodiment, and is not ordinary in the field of the present invention without departing from the gist of the present invention as claimed in the following claims. Anyone with knowledge will be able to make various changes.
