Oil Jet Injection Flow Measurement Device
The present invention relates to an oil jet injection flow measurement device, and more particularly, to an oil jet injection flow measurement device capable of testing the injection flow rate before mounting the oil jet to an actual engine.
Generally, heat inside the combustion chamber is released to the outside through exhaust gas, cylinder liner and piston. However, in the case of high power and high load engines, the piston may be deteriorated due to high heat load on the piston. Deterioration of the piston may cause problems in the durability of the piston, so oil jet is often adopted as a way to solve this problem. At this time, the injection flow rate of the oil jet is an important measure. If the injection flow rate is small, the expected cooling effect cannot be achieved, and if the injection flow rate is unnecessarily large, this results in an unnecessary increase in the capacity of the oil pump.
Therefore, the present invention is devised to measure the injection flow rate of the oil jet before the oil jet is actually mounted on the engine.
An object of the present invention is to provide an oil jet injection flow rate measuring device that can test the function and suitability of the oil jet by measuring the injection flow rate of the oil jet according to the pressure and temperature of the oil before mounting the oil jet to the actual engine, the oil jet It is to be able to utilize this in mass production.

To achieve the object of the present invention as described above, an oil bath for storing oil for supply to the oil jet; A temperature control device for controlling the temperature of the oil in the oil bath; An oil supply pipe connecting the oil bath and the main gallery of the oil jet; A supply pump installed at a predetermined point of the oil supply pipe to supply oil from the oil bath to the main gallery; A three-way valve installed on an oil supply pipe between the supply pump and the main gallery; A bypass pipe connecting the three way valve and the oil bath; A thermometer and a hydraulic sensor installed on an oil supply pipe between the three-way valve and the main gallery; Flow rate measuring means for measuring the flow rate of the oil injected and installed in each oil jet; An oil jet injection flow rate measuring apparatus is provided, comprising an oil collecting means for collecting oil from the flow rate measuring means and sending the oil back to the oil bath.
Hereinafter, the oil jet injection flow rate measuring apparatus according to the present invention as described above in detail with reference to the embodiment shown in the drawings as follows.
1 shows a configuration of the present invention, as shown, an oil supply pipe 3 is installed in an oil bath 1 for storing oil to be supplied to an oil jet 10 and is located at a predetermined point on the oil supply pipe 4. A feed pump 4 is installed to supply oil from the oil bath 1 to the main gallery 9 so that the oil can be dispensed from the main gallery 9 to each oil jet 10.
A three way valve 5 is installed at a predetermined point between the supply pump 4 and the main gallery 9 on the oil supply pipe 3, and a bypass pipe 6 is connected to the three way valve 5. And the other side of the bypass pipe 6 is connected to the oil bath 1. Therefore, the pressure of the oil supplied to the oil jet 10 is reduced as the opening degree of the three-way valve 5 is increased so that more oil is returned through the bypass pipe 6.
The oil bath 1 is provided with a temperature control device 2 capable of controlling the temperature of the oil by heating the oil. In addition, a thermometer 7 and a hydraulic sensor 8 are installed between the three-way valve 5 and the main gallery 9 to check the temperature and oil pressure of the oil.
A measuring flask 11 is installed at the bottom of each oil jet 10 to measure the volume of oil injected from the oil jet 10, and collects oil collected in the measuring flask 11 again to collect an oil bath. As the oil collecting means to be sent to (1), an oil collecting pipe 12 connecting the respective flask flask 11 and the oil bath 1 and a collecting pump 13 on which the oil collecting pipe 12 is installed are provided. It is provided.
Hereinafter, the operation of the present invention having the above configuration will be described.
First, each component is installed as shown in FIG. 1, and then oil is supplied from the oil bath 1 to the main gallery 9 using the feed pump 4. At this time, the temperature of the oil is adjusted using the temperature control device 2 and the temperature of the oil actually supplied through the thermometer 7 is checked. In addition, by adjusting the opening degree of the three-way valve (5) by adjusting the flow rate of the oil exiting the bypass pipe (6) to adjust the pressure of the oil and check the pressure of the oil actually supplied through the hydraulic sensor (8).
At the same time, when the oil is received from the measuring flask 11 installed at the bottom of each oil jet 10 and the volume thereof is measured to calculate the injection amount per injection time, the flow rate injected from each oil jet 10 can be measured. In general, since the injection flow rate of the oil is most affected by the pressure and temperature of the oil, it is possible to variously test the characteristics and performance of the oil jet 10 by measuring the injection flow rate for each temperature and pressure.
After the measurement is completed, the oil collected in the measuring flask 11 is collected by the collection pump 13 along the oil collection pipe 12 to the oil bath 1 again. By this process, this measurement can be repeated several times.
The present invention as described above has a means for adjusting the temperature and pressure and a means for measuring the injection flow rate, by changing the temperature and pressure, which is the most important variable of the oil jet injection flow rate and measuring the injection flow rate accordingly This can be tested before the oil jets are fitted to the engine and used in production.
