Abstract
Description
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 .

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
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 >
The above-mentioned two documents are characterized in that devices capable of implementing the invention are embedded in the internal combustion engine itself. The buried form described above can not confirm the state of the spray nozzle of a vehicle or a ship which does not have the above- The problem is the first one, and the second one is the problem that it is relatively uneconomical because the above functions must be provided for each engine.
The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to prevent cracks and seizures of a piston and a liner due to a position error of a spray nozzle of an internal combustion engine, And to obtain a tool for measuring the position of the spray nozzle for lubrication and cooling of the internal combustion engine capable of securing the reliability and improving the combat power of the trap.
In order to solve the above-described problems, the present invention is characterized in that a
