Abstract

PURPOSE:To raise the reliability and safety of an internal combustion engine in operation, by always indicating the quantity of lubricating oil in an oil reservoir, on a control panel through a detector, and automatically feeding the oil from a lubricating oil tank for supply into the oil reservoir, on the other hand, making it possible to indicate the occurrence of engine trouble caused by leakageof the oil. CONSTITUTION:While an engine 1 is operated with a proper quantity of lubricating oil, the level of the oil surface at the stationary temperature, is detected by an oil level detector 4, and this detected result is stored in a storage device of a control panel 18, by pushing a proper oil level set button 14. Next, the average of the lubricating oil level in an oil reservoir is always measured at preset intervals of time, and a solenoid operated opening/closing valve 5 is opened when the oil level is lowered, that is, said average of the oil level becomes lower than the preset degree. Accordingly, lubricating oil in a lubricating oil tank 2 for supply, is fed to the oil reservoir, as processing the signal of a flow meter 6. Said control panel 18 is also equipped with a make-up oil flow indicator 10, a make-up oil alarm buzzer 12, a lubricating oil consumption rate indicator 13, an improperness alarm lamp 15 for quantity of lubricating oil in the engine, and others, and all of these parts are used to check the condition of the lubricating oil.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to an apparatus for replenishing lubricating oil in an internal combustion engine and for managing the maintenance status of the internal combustion engine through this replenishment.

Conventional technology Lubricating an internal combustion engine is performed by circulating lubricating oil in an open-bottomed oil reservoir through each part of the engine. ,
Internal combustion engines are usually equipped with a warning device that warns of a drop in lubricating oil pressure, but even if this warning device is activated, it is often not possible to stop the engine immediately in cars or ships, so it is not practical. not enough. For this reason, in reality, the oil level in the oil reservoir is manually determined using a dipstick at regular intervals, and when it falls below a predetermined height, the required amount of oil is manually refilled from the replenishment lubricating oil tank. It's just something being done.

Problems to be Solved by the Invention In contrast, the present invention constantly displays the amount of lubricating oil in the oil reservoir on the control board via a detector, and automatically refills the lubricating oil from the replenishment lubricating oil tank. Furthermore, by detecting an abnormal increase in the amount of lubricating oil consumed by the engine, it is possible to prevent the occurrence of engine failure due to overstaying, and to warn of the necessity of engine maintenance.

Means to Solve the Problem When an internal combustion engine is operated for a long period of time, sludge adheres to the piston and piston ring, causing a phenomenon in the stairwell.
It is known that the amount of lubricant consumed increases dramatically as the wear of various parts increases.This abnormal increase in the amount of lubricated oil consumed may be due to oil leakage due to loosening of the mounting part of the lubrication system or cracks in the vibrator. In any case, it is important to accurately and quickly detect an increase in lubricant consumption (for maintenance purposes).To do this, it is necessary to keep the lubricant amount constant and A device that detects and displays the above-mentioned lubricant consumption amount is required.

According to this invention, a detector 4 for detecting the height of the lubricating oil level in the oil level, and an electromagnetic on-off valve 5 between the supply lubricating oil tank 2 and the oil reservoir are attached to the required internal combustion engine. At the same time,
A control board 18 is provided which is connected to these via conductive wires, and the control board has a replenishment lubricant flow rate indicator 10, a replenishment oil alarm buzzer 12, a lubricant consumption rate indicator 13, and an appropriate oil level setting button 14. , (Internal lubricating oil excess/deficiency warning lights 15, etc. are installed, and the control board 18 is equipped with setting values that indicate steady oil temperature and oil level height, as well as replenishment that corresponds to the oil level drop specific to the engine.) It consists of a storage device that stores each oil amount.

Embodiment Next, an embodiment of the present invention will be described with reference to the drawings. In the drawing, 1 is an engine, 2 is a supply lubricating oil tank, and 3 is a fuel flow rate sensor, all of which are existing devices.

Next, numeral 4 is a detector for detecting the level of the lubricating oil, and a liquid level gauge having a capacitance type sensor, an ultrasonic type sensor, etc. is used. Reference numeral 5 designates an electromagnetic opening/closing valve provided from the replenishment lubricating oil tank to the oil reservoir of the engine, and 6 represents a replenishment oil flow rate sensor.

Note that if the replenishment lubricating oil tank 2 is disposed at a lower position than the engine, a replenishment pump must be provided in place of the electromagnetic on-off valve 5.

Furthermore, 7 is a totalizing time meter that totals the operating time of the engine, 8 is a fuel cumulative flow rate display meter, 9 is a fuel meter reset button, 1 (
) is the replenishment lubricant flow rate indicator, 11 is the lubricant flow meter cent button, 12 is the replenishment oil alarm buzzer, 13 is the lubricant consumption rate indicator, 14 is the appropriate oil level cent button, 15 is the lubricant excess or deficiency in the engine. A warning light, 16 is an engine maintenance warning light, and 17 is a warning buzzer release button, these are all arranged on one control board 1; 3, and the control board 18, the fuel flow sensor 3, and the detector 4, the electromagnetic on-off valve 5 and the replenishment oil flow rate sensor 6 are connected to each other by conductive wires. A storage device is provided within the control board 18 to store the appropriate oil level position.

action The device of this invention is used in the following manner.

First, operate the engine with the appropriate amount of lubricating oil, and use the appropriate oil level setting button 14 to determine the position of the oil level when the oil temperature reaches a steady state.
Press to store it in the storage device of the control board 18. In this case, it is necessary to carry out the test in a normal trim condition on a horizontal road for a car and on a calm water surface for a ship. In any case, it is inevitable that the oil level measurement part will go up and down a little due to the vibrations of the car or the movement of the ship, so even in the case of a car, it is difficult to avoid
In the case of a ship, the average value for a period slightly longer than the natural period of rolling of the ship is stored.゛Thus, while the engine is operating, the average value of the lubricating oil level in the oil reservoir is constantly measured at the above-mentioned time intervals, and the average value is larger than the set value by ×III, for example, 10v.
z (Determined by taking into account allowances for temporary changes in oil level due to slope running on land-based heavy wheels and vertical and horizontal sway on ships)
If the oil level appears to be low, the electromagnetic on-off valve 5 or the replenishment pump that replaces it will automatically operate, and the control board will display the relationship between the replenishment oil amount commensurate with the engine-specific oil level drop. By storing this information, lubricating oil can be refilled while automatically monitoring the signal from the replenishing oil flow meter 6 until the specified oil level is reached.

Note that this lubricating oil supply may be performed in the following manner.

In other words, although it differs depending on the size of the engine, the control board determines the time period during which an amount of lubricating oil commensurate with the drop in the oil level flows through the on-off valve 5, or the time during which it is sent out from the replenishment pump in place of the electromagnetic on-off valve 5. It is stored in memory, and when there is a predetermined drop in the oil level, the electromagnetic on-off valve 5 is opened for a certain period of time, or the replenishment pump is operated for a certain period of time. In the case of this method, the accurate grasp of the amount of replenishment oil is somewhat inferior, but an oil level gauge is installed in the replenishment lubricating oil tank 2, and the amount of replenishment oil can be determined from this drop in the oil level. Is this method a method using the replenishment oil flow rate sensor 6? It has the advantage of being cheaper. Still another method may be to predetermine the operating time for one operation of the electromagnetic on-off valve 5 or the replenishment pump in place of it, and maintain the oil amount within the range between the oil level set value and the low x as position. As described above, while the engine is operating, the oil level is constantly monitored by the detector 4, and the above-mentioned replenishment is automatically performed as necessary.

After the engine has finished operating, the power to the control board 18 is manually turned off to stop the engine. The control board 18 may be turned on and off automatically by linking it with a vertical power supply or the like.

Furthermore, in the case of land vehicles and small ships whose continuous operation time is relatively short, human instructions may be used before starting the engine, or if the time is known in advance, human instructions may be used to set an appropriate time. It may also be possible to make a reservation for measuring the oil level and replenishing lubricating oil as necessary. In this case,
The oil pressure switch installed in the lubricating oil system detects when the engine is started, and after waiting for the lubricating oil temperature in the oil reservoir to reach a steady state, the standard oil level is automatically set. If this oil level falls outside a certain range, it is automatically replenished, or the interval between the standard oil level and the required 'MJ oil level during operation is allowed based on the interval between the standard oil level and the required oil level when the engine is stopped. Make it large within the range and issue a warning.

In either case, in the unlikely event that the detector sensor 4 malfunctions, the amount of lubricating oil in the oil reservoir may be too much or too little, which may impede operation. ]) to issue a warning of excess or deficiency. The accumulating time meter 10 is for accumulating the operating time, and reads the 4° fuel consumption/amount and the lubricant replenishment amount at predetermined time intervals, and calculates the lubricant consumption relative to the fuel consumption. The lubricating oil consumption rate or simply the amount of lubricating oil consumed per appropriate time is displayed on the lubricating oil consumption rate indicator 13. If this value exceeds a certain value, a warning is issued via a maintenance warning light 16.

In addition, when the lubricating oil in the replenishing lubricating oil tank has fallen below a certain level, it is detected by the integrated value of the lubricating oil flow rate indicator 10 or an oil level gauge installed in the replenishing lubricating oil tank (2). If this occurs, an alarm is issued via the replenishment oil alarm buzzer 12 to notify the need for replenishment. Of these alarms, only the buzzer can be stopped by pressing the warning buzzer release button 17.

Effects of the Invention As described above, the present invention is extremely efficient as it can always maintain the operation and maintenance of the engine in a perfect condition through proper lubrication and display of lubricant consumption.
