Description

Technical field

The present invention relates to the field of vehicles and, in particular, relates to a cylinder block of an engine, an engine having a cylinder block, and a vehicle having a cylinder block.

BACKGROUND

With the rapid development of automotive technology, the public need to protect the environment from the effects of automobiles is getting higher and higher, the quality of the engine gas-oil mixture separation system has a huge impact on vehicle emissions.

As a rule, in the gas-oil mixture separation system, a gas-oil separator is located in the upper part of the engine block and the oil pan is located in the lower part of the engine block. The gas-oil mixture separation channel and the oil return channel are embedded inside on both sides of the engine block. The inlet of the separation of the gas-oil mixture is located in the upper part of the engine crankcase and is attached to, and is in communication with the engine crankcase. The outlet of the gas-oil mixture separation channel is located in the upper part of the engine cylinder block and is in communication with the gas-oil separator inlet. The inlet of the oil return channel is in communication with the oil return window of the gas-oil separator. The release of the oil return channel is located in the lower part of the engine block and is in communication with the oil pan. In action, the gas-oil mixture (containing a large amount of sprayed oil, some steam, carbon dioxide and hydrocarbons, etc.), having a pressure inside the engine crankcase, enters the gas-oil mixture separation channel through the gas-oil mixture separation inlet, and then enters the gas-oil separator through the release of the gas-oil mixture separation channel. The gas-oil mixture inside the engine crankcase is effectively separated by a gas-oil separator; and the separated liquid return oil enters the oil return channel inside the engine block through the oil return outlet at the bottom of the separator and finally flows into the oil pan at the bottom of the engine block.

Since the engine is installed at a certain angle of inclination, in order to facilitate the return of oil, the engine can only be tilted to its side, which is provided with an oil return channel, so there is a significant limitation with respect to installation.

Therefore, it is desirable to have a technical solution to overcome or to reduce at least one of the above disadvantages that exist in the prior art, at least to some extent.

These terms are used only for the convenience of describing and simplifying the description of the present invention, and alone do not indicate or imply that the device or element referred to by reference must have a specific orientation and must be designed or operated in a specific orientation. Therefore, these terms should not be construed as limiting the scope of the present invention.

As shown in FIG. 1, the present embodiment provides an engine block unit 1. Engine block 1 includes at least two channels; Each of the channels is located inside the wall of the cylinder block and passes directly from the upper part of the block 1 of the engine cylinders to its lower part. The engine block 1 has a left side and a right side in the “first direction”, which are considered to be both sides of the engine block 1, mentioned below. The channels include the first channel 2 and / or the second channel 3, as shown in FIG. 1, and FIG. 1 is used only to illustrate that the channels are located on both sides of engine block 1, which does not indicate or imply that only two channels are provided. In fact, more than two channels are within the protection scope of the present invention. The channels are located on both sides of the engine block 1 in the first direction of the engine block 1, such as the first channel 2 and the second channel 3, placed on both sides of the engine block 1 in the first direction of the engine block 1 in FIG. one.

Each of the channels has an oil return inlet, an oil return release and a gas-oil mixture separation inlet; as shown in FIG. 1, 3 and 4, the first channel 2 has the first oil inlet 21, the first oil return outlet 22 and the first gas-oil mixture separation inlet 6, and the second channel 3 has the second oil return inlet 31, the second oil return outlet 32 and the second separation inlet 8 gas oil mixture. The oil return channel is located at the bottom of engine block 1 and is in communication with the oil pan (not shown in the drawings). Liquid return oil from the channel flows into the oil pan through the release of the oil return channel. The oil return inlet of the channel is located in the upper part of the engine cylinder block 1 and is in communication with a gas-oil separator (not shown in the drawings) in the upper part of the engine cylinder block 1. Liquid return oil, separated by a gas-oil separator, flows into the channel through the channel's oil return inlet. The gas-oil mixture separation inlet is in communication with the engine crankcase 4 and is located between the oil return inlet and the oil return release. The gas-oil mixture, having pressure in the crankcase 4 of the engine, flows into the gas-oil separator through the inlet of the separation of the gas-oil mixture in order to carry out separation processing of the gas-oil mixture with a gas-oil separator.

Both sides of an engine block in accordance with the present embodiment are provided with channels, and the channels can not only successfully carry out oil return, but also serve as a gas-oil separation channel. Therefore, when the engine is installed, the inclined installation of the engine block, being tilted to the left or right, causes the channel on its side to meet the requirements and operate normally so as not to affect the gas-oil separation and oil return functions, thereby solving the problem restrictions on the location of the engine installation at a modern technical level.

In the embodiment of the present invention, the channel also has a protective part that is located above the inlet of the gas-oil separator so that it can stop the liquid return oil entering the channel through the oil return inlet from entering the gas-oil mixture into the inlet of the separation, for example, the first protective part 5 shown in FIG. 2 and 3, and also, for example, the second protective part 7 shown in FIG. 4 and 5. Since the first protective part 5 is located above the first gas-oil mixture separation inlet 6, and the second protective part 7 is located above the second protective part 8, first, liquid return oil B can be prevented from entering the engine crankcase 4 through the gas-oil mixture separation inlet and secondly, small drops of oil scattered by the rotation of the crankshaft in the engine crankcase 4 are prevented from entering the channel through the inlet of the separation of the gas-oil mixture, which can have an adverse effect on the split no gas oil mixture.

In an embodiment of the present invention, the channel has an inlet section, a converging section and an outlet section; the inlet section is connected to the oil return inlet, the outlet section is connected to the oil return outlet, and the protective part and the gas-oil mixture separation inlet are both located at the converging section. More specifically, the first channel 2 includes a first inlet section 23, a first converging section 24 and a first exhaust section 25; the first inlet section 23 is in communication with the first converging section 24, and the first converging section 24 is in communication with the first exhaust section 25. The first inlet section 23 is connected to the first inlet 21 of the oil return; the first exhaust section 25 is connected to the first release 22 of the oil return; the first protective part 5 and the first inlet 6 of the gas-oil mixture separator are both located in the first converging section 24. The second channel 3 includes a second inlet section 33, a second converging section 34 and a second exhaust section 35; the second inlet section 33 is in communication with the second converging section 34; the second converging section 34 is in communication with the second exhaust section 35. The second inlet section 33 is connected to the second oil return inlet 31; the second outlet section 35 is connected to the second issue 32 of the oil return; the second protective part 7 and the second inlet 8 of the gas-oil mixture separator are both located in the second converging section 34.

The first channel 2 is taken as an example to describe the technological process. During use, the gas-oil mixture A, having a pressure inside the crankcase 4 of the engine, enters the gas-oil separator through the first gas-oil mixture separation inlet 6, in order to perform the gas-oil mixture separation processing with a gas-oil separator, and separated liquid return oil B passes through the first inlet section 23 the first converging section 24 and the first exhaust section 35 successively through the first oil return inlet 21, and finally flows into the oil pan through the first oil return outlet 22. The first protective part 5 is located above the first gas-oil mixture separation inlet 6, so when the liquid return oil B passes through the first converging section 24, the liquid return oil B cannot get into the first gas-oil mixture separation inlet 6 under the shielding effect of the first protective part 5 and be protected from contact with the crankshaft in the crankcase 4 of the engine, thus avoiding the resulting large amount of oil vapor.

FIG. 2 and 3 are schematic views of the first channel 2. FIG. 2 and 3, the first channel 2 includes two first inlet sections 23 and two first exhaust sections 25, two first inlet sections 23 are located on both sides of the first protective part 5 and the first gas-oil mixture separation inlet 6 in the second direction of the engine block 1, and the two first exhaust sections 25 are located on both sides of the first protective part 5 and the first inlet 6 of the separation of the gas-oil mixture in the second direction of the engine block 1. The first two inlet sections 23 are placed on the same line or symmetrically, return oil from the first two inlet sections 23 is drained onto the first converging section 24, and then drained from the first two exhaust sections 25. The “second direction” is essentially perpendicular to the “first direction”, the term The "substantially" used in the materials of the present application is defined as the fact that they do not need to be strictly perpendicular to each other, and a slight deviation can be interpreted as "essentially perpendicular."

Similarly, FIG. 4 and 5 show schematic views of the second channel 3. FIG. 4 and 5, the second channel 3 includes two second inlet sections 33 and two second exhaust sections 35, two second inlet sections 33 are located on both sides of the second protective part 7 and the second inlet 8 of the gas-oil mixture separation in the second direction of the engine block 1, and two second exhaust sections 35 are located on both sides of the second protective part 7 and the second gas-oil mixture separation inlet 6 in the second direction of the engine cylinder block 1. The two second inlet sections 33 are placed on the same line or symmetrically; return oil from the two second inlet sections 33 flows into the second converging section 34, and then, is discharged from the two second exhaust sections 35.

It should be noted that the first channel 2 and the second channel 3 may include only one inlet section and one outlet section, and may also include more than two inlet sections and more than two outlet sections, while it is guaranteed that the first channel 2 and The second channel 3 is located respectively on both sides of the engine block 1 in the first direction of the engine block 1.

Referring to FIG. 2 and 3, again, the connection point 25a of the first outlet section 25 and the first converging section 24 of the first channel 2 is in the form of a funnel, which has a large upper end and a small lower end. Liquid return oil B, successively returning from the first outlet section 25 and the first converging section 24, gets into the funnel-shaped wall body, and then flows into the oil pan along the wall body; funnel shape can play a positive role in drainage. Preferably, the first inlet section 24 may be L-shaped and has a bumped oblique subsection 23a and a drainage subsection 23b, of which the bumpy bumpy subsection 23a extends substantially horizontally and is attached to the first oil return inlet 21 to ensure that the liquid return oil B returns evenly. The drainage subsection 23b extends substantially vertically and is connected between the bumping oblique subsection 23a and the first converging section 24; Liquid return oil B returning from the first oil return inlet 21 is introduced from the buffer inclined subsection 23a to the first converging section 24. In addition, a plurality of first oil inlets 21 may be provided, possibly three, and a plurality of first oil inlets 21 are placed at intervals in the buffer oblique subsection 23a in the second direction.

It should be noted that the second channel 3 may adopt the structure in the embodiment described above and, of course, may also adopt the structure of FIG. 4 and 5. The design of the second channel 3 shown in FIG. 4 and 5 will be described in detail below.

In the second channel 3, both sides of the second converging section 34 in the second direction of the engine block are respectively provided with a side wing structure; the second protective part 7 is formed on the upper wall of the side wing structure, and the second gas-oil mixture separation inlet 8 is located in the bottom wall of the side wing structure. Liquid return oil B, continuously returning from the second inlet section 33 and the second converging section 34, enters the side wing structure and then flows into the oil pan through the second exhaust section 35 so that the side wing design can play a positive role in draining.

Preferably, the second protective part 7 is made in the form of an inverted V-shaped or L-shaped and has a horizontal protective wall 7a and a drainage wall, which gradually inclines to the central axis of the second channel from top to bottom; the horizontal protective wall 7a extends in the second direction, and the drainage wall 7b is located closer to the central axis of the second channel 3 than to the second gas-oil mixture separation inlet 8, so that it can prevent liquid return oil B from entering the engine crankcase 4 through the second separation inlet 8 gas oil mixture. The direction of gas outflow from the second inlet 8 of the separation of the gas-oil mixture is tilted upwards.
