Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a position measuring apparatus for measuring the position of a spray nozzle for lubricating and cooling an internal combustion engine,

The present invention relates to a tool for measuring the position of a nozzle of a lubricating and cooling spray of an internal combustion engine, and more particularly to a tool for accurately locating a cooling spray of an internal combustion engine cylinder with a human hand, So that maintenance of the internal combustion engine can be easily performed.

Since the piston and liner of the internal combustion engine must ensure continuous supply of lubricating oil for lubrication and cooling, the spray provided on the inner bottom of the engine must supply cooling lubricating oil linearly to the oil hole provided on one side of the piston.

However, there is a phenomenon that the position of spray is changed due to disassembly and assembling process for maintenance and production of pistons and liners, poor assembly of spray nozzles, thermal deformation of engine cylinders, and the like.

This phenomenon has a problem in that normal operation of the engine can not be guaranteed by causing damage such as cracking (cracking) of the piston and liner or detachment by deteriorating the supply of lubricating oil for lubricating and cooling while operating the engine have.

In addition, since the spray nozzle, which is an internal part of the engine, is a part that can not be confirmed until the engine is completely disassembled, the position inspection should be accurately performed at the time of disassembly and maintenance. Conventionally, after the piston and the liner are reassembled, Since only limited inspection is performed, there is a concern of maintenance failure and large accident, so a tool capable of accurately measuring the position of the spray nozzle is needed.

The technique for measuring the position of the spray nozzle as described above can be referred to as a diesel engine oil injector oil spray locating system which exists in the form of a tool rather than the form of a tool and is described in German Patent Application No. DE19745817A1 .

1, the present system can be mounted on the nozzle end 21 of the oil injector 20, and includes a light emitting element 50 at a front center of a single nozzle end of the attachment apparatus 40, A light emitter 60 is provided on the front surface of the light emitting device and a light receiving element 70 is mounted on the oil hole of the piston.

When the light emitter 60 emits light to the light-receiving element 70, the light-emitting element 50 emits the emitted light at its center, and the light-receiving element 70 emits light And the light emitted from the light emitting element 50 is transmitted through the light receiving display device 71.

A control device for a spray-guided cylinder internal combustion engine, which is disclosed in Japanese Patent Application Laid-Open No. 2009-024682, is also operated in a manner similar to the above-described technique. In order to prevent the deterioration of the combustion state due to the direction of the ground electrode of the spark plug.

2, in the injection engine 11 inside the spray guide type cylinder of the related art, the ground electrode 38 protruding in the spray range at the side end of the spark plug 20 intercepts a part of the spray It is described that the spray forming state changes when the direction of the ground electrode 38 changes.

In addition, the combustion improvement control for determining the combustion state of each cylinder during the operation of the compression stroke injection (stratified charge combustion) or the suction and compression stroke division injection (weak layer combustion) and improving the combustion state when the combustion deterioration of one cylinder is detected .

The combustion improvement control is characterized in that the fuel to be injected is divided and injected during the compression stroke of the combustion deterioration cylinder or the electric cylinder, or the total discharge period of the ignition is extended to the delay angle side and the fuel injection timing is corrected to the advance side ≪ / RTI >

[ .

Therefore, as shown in FIG. 6A, the rod 200 is moved upward so that the user can directly discover the spray nozzle.

In general, the spray nozzle is provided at a specified position on the inner side of the internal combustion engine according to a specification specified in the design. The measurement hole 301 provided in the guide part 300 is connected to the laser pointer 110 The laser pointer 110 is provided in a direction parallel to the upper side of the spray nozzle 110 as shown in FIG.

Accordingly, it is possible to separate the handle 250 provided at the upper end of the rod 200 and replace it with a housing part 100 of a size capable of being mounted on one side of the internal combustion engine badge estimated to accurately locate the spray nozzle .

9, a fixing protrusion 201 is provided at one end of the rod 200 and the rod fixing hole 151 is also formed in one side parallel to the fixing protrusion 201, It is possible to prevent the rod 200 from turning to the left and right so that it is possible to know whether the spray nozzle position is searched and the position is deformed more precisely.

As shown in FIG. 7, in order to enable the user to visually locate the spray nozzle through the above-described operation, grooves 101 are provided on both left and right sides of the upper surface of the housing part 100 So that one end of the upper part of the housing part 100 can be viewed as a sector.

8, the position of the spray nozzle can be easily seen from the left and right through the guide part 300 when the position of the spray nozzle is detected, So that the position of the spray nozzle can be visually confirmed through the laser pointer 110 by operating the part 300 up and down through the rod 200. [

The laser pointer 110 can exchange and maintain the battery through the battery holder 119 provided at the upper end of the laser pointer 110. The laser pointer 110 has a handle 250 The knurled side end portion of each of the above-described embodiments can be more appropriately implemented. On the other hand, the shape of the knurling allows a practitioner to freely consider a legitimate method according to a situation, even if the shape or shape of the rule is changed through a simple design change.

Also, the guide portion 300 can be replaced with a guide portion 300 having a size similar or identical to that of the cylinder of the internal combustion engine so that the internal combustion engine of various sizes can be measured. As shown in FIG. 9, Such as a screw, a pin, or a rivet, so that the attachment and detachment of the connector 200 can be performed.

Therefore, it is possible to solve the conventional problems by making it possible to visually inspect the internal combustion engine of various sizes with a tool for measuring the position of the spray nozzle for lubrication and cooling of the internal combustion engine as described above.
