Description
Technical Field
The present invention relates to an adapter for mounting a pressure sensor and a sensor.
Background
In recent years, in marine engines, fuel injection control has been increasingly electronized. In an electronic engine, the following operations are performed: the deviation between the cylinders of the fuel injection is corrected by detecting the in-cylinder pressure (hereinafter referred to as "in-cylinder pressure") with a sensor. Further, optimization of engine control by feedback of the detected cylinder internal pressure, detection of an engine state by cylinder internal pressure detection, and the like are expected to be advanced in the future. Under such a background, it is becoming more and more important to detect the cylinder internal pressure with high accuracy.
Patent document 1: international publication No. 2008/071022
Disclosure of Invention
Problems to be solved by the invention
The pressure sensor for detecting the cylinder internal pressure described in patent document 1 has a detection unit for detecting the pressure at the distal end. The pressure sensor is attached to the engine via a pressure sensor attachment adapter (hereinafter simply referred to as "adapter"). The adapter is provided with a gas flow path extending from the cylinder of the engine. When the pressure sensor is attached to the adapter, the detection portion is exposed to the flow path. Since the pressure in the flow path is equal to the cylinder internal pressure, the value of the cylinder internal pressure can be obtained by detecting the pressure in the flow path with a pressure sensor.
The portion of the pressure sensor exposed to the flow path is also exposed to the exhaust gases from the engine. Therefore, deposits of dust, lubricating oil residue, and the like accumulate at this portion. The deposition of deposits on the detection portion of the pressure sensor causes a reduction in detection accuracy.
The adapter includes an indicator cock at an end opposite to the engine to remove deposits accumulated in the flow path. When the indicator cock is opened during operation of the engine, gas discharged from the engine passes through the flow path at a high speed and is discharged from the indicator cock. The deposits accumulated in the flow path are removed by the high-speed gas flow.
In the technique described in patent document 1, in order to suppress deposition of deposits, a connection opening portion of the pressure sensor with respect to the gas flow passage and a wall surface of the flow passage are smoothly connected in the same plane. However, this technique cannot efficiently strip the temporarily deposited deposits.
The present invention has been made in view of the above problems, and an object thereof is to provide an adapter for mounting a pressure sensor, which can efficiently peel off deposits accumulated on the tip end of the pressure sensor.
Means for solving the problems
In order to solve the above problem, an adapter for mounting a pressure sensor according to an aspect of the present invention includes: a mounting portion that fixes the pressure sensor and has an opening for exposing the detection portion of the pressure sensor; and a casing having a passage wall that forms a passage for the gas, the casing having a contour such that: when the pressure sensor is mounted, the side surface side of the detection section is exposed to the front surface side as viewed from the extending direction of the flow channel.
Another aspect of the present invention is a sensor. The sensor includes: a pressure sensor provided with a detection unit; and a pressure sensor mounting adapter having: a mounting portion that fixes the pressure sensor and has an opening for exposing a detection portion of the pressure sensor; and a housing having a flow path wall forming a flow path for the gas, the housing having a contour such that: when the pressure sensor is mounted, the side surface side of the detection portion is exposed to a much larger extent than the front surface side as viewed from the extending direction of the flow path.
In addition, any combination of the above-described constituent elements, and a form in which the constituent elements and expressions of the present invention are mutually replaced among a method, an apparatus, a system, and the like are also effective as the form of the present invention.
ADVANTAGEOUS EFFECTS OF INVENTION
According to the present invention, it is possible to realize a pressure sensor mounting adapter capable of efficiently peeling off deposits accumulated on the tip end of a pressure sensor.

Detailed Description
The present invention will be described below based on preferred embodiments with reference to the drawings. The same or equivalent components, members and processes shown in the respective drawings are denoted by the same reference numerals, and overlapping descriptions are appropriately omitted.
[ embodiment 1]
Fig. 1 is a perspective view showing a pressure sensor mounting adapter 1 according to embodiment 1 of the present invention.
In fig. 1, a pressure sensor 15 having a detection unit 16 provided at the distal end thereof is attached to the pressure sensor mounting adapter 1. Further, an engine (not shown) is located below the pressure sensor mounting adapter 1, and an indicator cock (not shown) is located above the pressure sensor mounting adapter 1. A flow path 12 through which gas passes extends from within the cylinder of the engine in the direction of arrow X to an indicator tap.
The pressure sensor mounting adaptor 1 includes a mounting portion 10 and a housing 11, the mounting portion 10 fixing a pressure sensor 15 and having an opening 13 for exposing a detection portion 16 of the pressure sensor 15. The housing 11 comprises a flow path wall 14, which flow path wall 14 forms a flow path 12 for the gas, having a profile such that: when the pressure sensor 15 is mounted, the side surface side of the detection section 16 is exposed to a much larger extent than the front surface side as viewed from the extending direction of the flow path 12.
The pressure sensor 15 is inserted into the mounting portion 10 from the left side of the drawing, and is mounted by being pushed in the direction of arrow Y. When the pressure sensor 15 is mounted, the detection portion 16 of the pressure sensor 15 is exposed to the flow path 12.
An opening 13 for exposing a detection portion 16 of the pressure sensor 15 to the flow channel 12 is formed in the flow channel wall 14 in the housing 11. As described above, when the pressure sensor 15 is attached to the attachment portion 10, the detection portion 16 is exposed to the flow path 12 from the opening 13.
Fig. 2 is a sectional view taken along line a-a' of the pressure sensor mounting adapter 1 of fig. 1 as viewed from below. The flow path 12 extends in the X direction, i.e., a direction viewed from the front side to the back side of the paper.
As shown in fig. 2, the flow path wall 14 has a curved shape in cross section orthogonal to the extending direction of the flow path 12. The opening 13 is formed on the bulging surface 20 of the flow path wall 14, that is, the convex surface side of the flow path wall 14.
Fig. 3 is an enlarged view of the region 30 of fig. 2.
As shown in fig. 3, the detection unit 16 of the pressure sensor 15 is exposed to the flow channel 12 from the opening 13 provided in the flow channel wall 14. The flow path wall 14 has a curved shape in cross section orthogonal to the extending direction of the flow path 12, and the opening 13 is formed on the bulging surface 20 of the flow path wall 14. Therefore, the side surface 31 of the detection section 16 is exposed to the flow path 12 more than the front surface 32. In other words, the flow path wall 14 is shaped such that the side surface side of the detection section 16 is exposed to the flow path 12 more than the front surface side when viewed from the extending direction of the flow path 12.
Fig. 4 is a sectional view taken along line B-B' of the pressure sensor mounting adapter 1 of fig. 1, as viewed from the right side. The flow path 12 extends in the X direction, i.e., in the direction from the bottom to the top of the paper.
As described above, the flow path 12 extends from the engine (not shown) located below the pressure sensor mounting adapter 1 in fig. 4. Therefore, the gas discharged from the cylinder of the engine flows from the bottom to the top in the flow path 12. Therefore, the deposits 17 caused by the gas are deposited on the upstream side of the detection portion 16, that is, on the lower side of the detection portion 16 in fig. 4.
As described above, the side surface 31 of the detection unit 16 is exposed to the flow channel 12 more than the front surface 32 when viewed from the extending direction (X direction) of the flow channel 12. Therefore, the deposit 17 is deposited thicker on the side surface side 31 of the detection portion 16 than on the front surface side 32 of the detection portion 16.
As described above, the flow path 12 extends to the indicator cock (not shown) located above the pressure sensor mounting adapter 1 in fig. 4. When the indicator cock is opened during operation of the engine, gas discharged from the engine passes through the flow path 12 at a high speed and is discharged from the indicator cock.
At this time, the flow velocity of the gas in the flow channel 12 is higher on the side surface side 31 of the detection unit 16 than on the front surface side 32 of the detection unit 16. Therefore, the force F1 received by the deposit 17 deposited on the side surface side 31 from the gas is stronger than the force F2 received by the deposit 17 deposited on the front surface side 32. The force F1 acts to peel off the deposited material 17 from the side surface 31 that has been deposited thicker.
As described above, the deposits 17 are deposited thicker on the lateral side 31 than on the front side 32. Therefore, most of the deposit 17 is peeled off from the gas flowing at high speed on the side surface side 31. In addition, on the front side 32, the deposits 17 are deposited thinly. Therefore, when the deposits 17 deposited on the side surface side 31 are subjected to a peeling action from the gas, the deposits 17 deposited on the front surface side 32 are easily separated. In this way, the sediment 17 accumulated in the detection portion 16 is efficiently peeled off and removed from the indicator cock.
Fig. 5 is a sectional view showing the pressure sensor mounting adapter 2 according to the comparative example. Fig. 5 corresponds to a cross-sectional view (fig. 2) of the pressure sensor mounting adapter 1 according to embodiment 1. The shape of the flow path wall 14 of the pressure sensor mounting adapter 2 is different from that of the pressure sensor mounting adapter 1. The other structure of the pressure sensor mounting adapter 2 is the same as that of the pressure sensor mounting adapter 1.
As shown in fig. 5, the cross-sectional shape of the flow path wall 14 perpendicular to the extending direction of the flow path 12 has a rectangular shape. Therefore, the opening surface of the opening 13 formed in the flow path wall 14 is parallel to the detection surface of the detection section 16.
Fig. 6 is an enlarged view of the region 30 of fig. 5.
As shown in fig. 6, the detection unit 16 of the pressure sensor 15 is exposed to the flow channel 12 from the opening 13 provided in the flow channel wall 14. At this time, the cross-section of the flow path wall 14 perpendicular to the extending direction of the flow path 12 has a rectangular shape, and the opening surface of the opening 13 is parallel to the detection surface of the detection section 16. Therefore, the detection section 16 is uniformly exposed to the flow path 12 over the entire region 33.
Fig. 7 is a sectional view of the pressure sensor mounting adapter 2 as viewed from a direction orthogonal to fig. 5, and corresponds to fig. 4.
Similarly to fig. 4, the deposits 17 are deposited on the upstream side of the detection portion 16, that is, on the lower side of the detection portion 16 in fig. 7.
However, unlike fig. 4, the detection section 16 is uniformly exposed to the flow path 12 when viewed from the extending direction (X direction) of the flow path 12. Therefore, the deposits 17 are deposited with a uniform thickness on both the side surface side 31 and the front surface side 32. Therefore, in the case of the pressure sensor mounting adapter 2, even if the indicator cock is opened during the engine operation, the deposits 17 cannot be peeled off as efficiently as the pressure sensor mounting adapter 1.
As described above, according to the pressure sensor mounting adapter 1 of embodiment 1, the flow path wall 14 has a contour such that the side surface side of the detection section 16 is exposed to a larger extent than the front surface side when viewed from the extending direction of the flow path 12, and therefore, the deposits accumulated in the detection section 16 can be efficiently peeled off.
In particular, the flow path wall 14 preferably has a curved shape in cross section orthogonal to the extending direction of the flow path 12. The opening 13 is preferably formed on a convex surface side, which is a surface on the bulging side of the flow path wall 14. According to this configuration, the surface area of the side surface side of the detection section 16 exposed to the flow channel 12 can be increased, and therefore, the deposits can be more efficiently peeled off.
[ 2 nd embodiment ]
Fig. 8 is a sectional view showing the pressure sensor mounting adapter 3 according to embodiment 2. Fig. 8 corresponds to a cross-sectional view (fig. 2) of the pressure sensor mounting adapter 1 according to embodiment 1. The shape of the flow path wall 14 of the pressure sensor mounting adapter 3 is different from that of the pressure sensor mounting adapter 1. The other structure of the pressure sensor mounting adapter 3 is the same as that of the pressure sensor mounting adapter 1.
As shown in fig. 8, the cross-sectional shape of the flow path wall 14 perpendicular to the extending direction of the flow path 12 has a V-shape. The opening 13 is formed at a peak 22 on the mountain side of the flow path wall 14. The V-shape herein also includes a substantially V-shape.
As shown in fig. 8, the detection unit 16 of the pressure sensor 15 is exposed to the flow channel 12 from the opening 13 provided in the flow channel wall 14. At this time, since the flow path wall 14 has a substantially V-shape when viewed from the extending direction of the flow path 12 and the opening 13 is formed at the apex 22 of the flow path wall 14 on the mountain side, the side surface side of the detection section 16 is exposed to the flow path 12 more than the front surface side.
According to the present embodiment, the surface area of the side surface side of the detection section 16 exposed to the flow channel 12 can be further increased, and therefore, the deposits can be more efficiently peeled off.
[ 3 rd embodiment ]
Fig. 9 is a sectional view showing the pressure sensor mounting adapter 4 according to embodiment 3. Fig. 9 corresponds to a cross-sectional view (fig. 2) of the pressure sensor mounting adapter 1 according to embodiment 1. The shape of the flow path wall 14 of the pressure sensor mounting adapter 4 is different from that of the pressure sensor mounting adapter 1. The other structure of the pressure sensor mounting adapter 4 is the same as that of the pressure sensor mounting adapter 1.
As shown in fig. 9, the cross section of the flow channel wall 14 perpendicular to the extending direction of the flow channel 12 has an angular U-shape. The opening 13 is formed at the bottom of the inner wall 23 on the bulging side. The width W1 of the opening 13 is larger than the width W2 of the bulging-side inner wall 23.
As shown in fig. 9, the detection unit 16 of the pressure sensor 15 is exposed to the flow channel 12 from the opening 13 provided in the flow channel wall 14. At this time, the flow path wall 14 has an angular U-shape when viewed from the extending direction of the flow path 12, and the width W1 of the opening 13 is larger than the width W2 of the inner wall 23 on the bulging side. Therefore, the side surface side of the detection section 16 is exposed to the flow channel 12 more than the front surface side.
According to the present embodiment, exposure of the front portion of the detection section 16 to the flow channel 12 can be suppressed, and therefore deposition of deposits on the front portion of the detection section 16 can be prevented.
In one embodiment, the mounting portion 10 includes a regulating portion (not shown) that regulates the insertion depth of the pressure sensor 15 to a depth not less than a predetermined depth. The restricting portion may be formed using a stopper, for example.
According to this structure, the pressure sensor 15 can be prevented from being excessively exposed to the inside of the flow path 12.
In one embodiment, the opening is circular. Since the pressure sensor 15 is circular, the pressure sensor 15 having the cylindrical detection portion 16 can be inserted into the flow path 12. The opening may have a shape mainly including a curve other than a circle, for example, an oval shape.
According to this configuration, since the pressure sensor 15 having the detection portion 16 in a cylindrical shape can be used, the exposure of the front portion of the detection portion 16 to the flow path 12 can be further suppressed.
[ 4 th embodiment ]
Fig. 1 is a perspective view showing a sensor according to embodiment 4 of the present invention. The sensor includes a pressure sensor 15 having a detection unit 16 and a pressure sensor mounting adapter 1. The pressure sensor mounting adapter 1 has the same structure as that described in embodiment 1, and therefore, redundant description thereof is omitted. That is, the sensor of the present embodiment is configured by attaching a pressure sensor to the pressure sensor attachment adaptor of embodiment 1. According to the present embodiment, a sensor capable of efficiently peeling off deposits accumulated in the detection section 16 can be realized.
The present invention has been described above based on several embodiments. These embodiments are illustrative, and it will be understood by those skilled in the art that various changes and modifications can be made within the scope of the present invention, and such changes and modifications also fall within the scope of the present invention. Accordingly, the description and drawings in this specification are to be regarded in an illustrative rather than a restrictive sense.
Hereinafter, a modification will be described. In the description of the modified examples, the same or equivalent constituent elements and members as those of the embodiment are denoted by the same reference numerals. The description overlapping with the embodiment is appropriately omitted, and the description is focused on the structure different from the embodiment.
[ modification 1]
Fig. 10 is a sectional view showing a pressure sensor mounting adapter 5 according to a modification. Fig. 10 corresponds to a cross-sectional view (fig. 2) of the pressure sensor mounting adapter 1 according to embodiment 1. The shape of the flow path wall 14 of the pressure sensor mounting adapter 5 is different from that of the pressure sensor mounting adapter 1. The other structure of the pressure sensor mounting adapter 5 is the same as that of the pressure sensor mounting adapter 1.
As shown in fig. 10, the flow path wall 14 has a V-shaped convex portion 24 when viewed from the extending direction of the flow path 12. The opening 13 is formed at the apex 25 of the convex portion 24 of the flow path wall 14.
As shown in fig. 10, the detection unit 16 of the pressure sensor 15 is exposed to the flow channel 12 from the opening 13 provided in the flow channel wall 14. The flow path wall 14 has a V-shaped convex portion 24 when viewed from the extending direction of the flow path 12, and the opening 13 is formed at a vertex 25 of the convex portion 24 of the flow path wall 14. Therefore, the side surface side of the detection section 16 is exposed to the flow channel 12 more than the front surface side.
According to this modification, the surface area of the side surface side of the detection section 16 exposed to the flow channel 12 can be increased, and therefore the deposits can be more efficiently peeled off.
[ modification 2]
The opening may also have other shapes, for example, rectangular. According to this modification, the processing becomes simple. This advantage is also obtained when a straight line such as a square is mainly used.
In addition, any combination of the above-described embodiments and modifications is also useful as an embodiment of the present invention. The new embodiment resulting from the combination has the effects of the combined embodiments and the modified examples.
