Definitions
- the present invention relates to the testing of internal combustion engines during their test bench. It relates more particularly to measuring the lubricant consumption of such engines.
- Publication JP3633926 discloses a device for measuring the oil consumption of an internal combustion engine.
- This measuring device comprises a conduit bringing oil from an oil sump to a storage tank providing a supply of oil sucked by a pump to measuring devices.
- This measuring device further comprises a solenoid valve, a sample collection pump, an air vent, a mass flow meter and a measuring device connected to the mass flow meter. A value of the oil mass sucked into the air is measured by the flow meter, the engine oil consumption is then displayed.
- This device for measuring the oil consumption of an internal combustion engine operates with two pumps. A first to suck oil from the motor housing to the storage tank, and a second pump to take the sample to be measured.
- this device comprises two oil circulation paths, one bringing the lubricating liquid to the intermediate reservoir, the other bringing the oil to the measuring instruments. And two separate measurement elements.
- the device of the prior art does not make it possible to carry out the oil draining and replenishment of the engine during a test.
- the present invention proposes to overcome the drawbacks of the prior art, by providing a method and a device for measuring the oil consumption of an internal combustion engine, which is particularly simple to install and to use without requiring pump to bring the oil to the measuring tank, and able to perform the draining and refilling of the engine oil during a test.
- the invention proposes a method for measuring the quantity of oil consumed by an internal combustion engine comprising an oil sump for its supply of lubricating liquid, characterized in that it comprises at least the steps consisting in :
- - b) measure and memorize a first value of a mass of oil contained in the measuring tank.
- - c) subject the oil contained in the measuring tank to the thrust of a gas under pressure causing the oil to rise from the measuring tank to the oil sump.
- the oil consumption of the internal combustion engine is obtained by realizing the difference between the first and the second value of the mass of oil contained in the measuring tank.
- the present invention furthermore proposes a device for measuring the oil consumption of an internal combustion engine equipped with an oil sump, comprising a hermetic measuring tank, at least a first duct bringing the oil of the oil sump oil to the measuring tank, means for measuring a characteristic quantity of the oil thus diverted and an electronic control unit able to control different effectors, for the implementation of the method previously described characterized in that it comprises:
- a second duct provided with movable closing means, connecting said measuring tank to a source of pressurized gas, the opening of which causes the lubricating liquid present in the measuring tank to rise towards the oil sump of the engine under test; this being then subjected to the thrust of the gas under pressure.
- the measuring tank is positioned below the oil sump of the engine whose oil consumption is measured.
- closure means of the first conduit are constituted by a solenoid valve and the closure means of the second conduit are constituted by a pneumatic valve.
- the means for measuring a characteristic of the oil is a scale on which the measuring reservoir is placed.
- the device comprises a conduit for discharging the used lubricating liquid from the oil sump provided with an evacuation valve allowing or preventing the passage of used oil from the sump to a recovery tank.
- the device according to the invention also comprises a supply duct for fresh lubricating liquid from a supply tank, said duct being provided with a valve allowing or preventing the circulation of the lubricating liquid from the storage tank to the measuring tank.
- FIG. 1 a schematic view of the measuring device according to the invention connected to the casing of FIG. engine oil whose lubricant consumption is to be measured
- FIG. 2 a schematic view of the device of FIG. 1 equipped with means making it possible to carry out the emptying and automatic replenishment of the engine oil.
- FIG. 1 there is an oil pan for the recovery of the lubricating liquid of the various elements of the engine.
- a discharge orifice of the lubricating liquid 8 is arranged in the lower part of the casing 7.
- This orifice 22 communicates with a solenoid valve 9 allowing or prohibiting the passage of lubricant 8 to the measuring device.
- the lubricating liquid 8 moving from the oil sump of the engine to the measurement reservoir encounters, from upstream to downstream, the following elements connected to each other: a solenoid valve 9 allowing or prohibiting the passage of the lubricant 8 a first intermediate conduit 1 1, a quick coupling socket 13, a second conduit 15 bringing the lubricating liquid to the measuring tank and - a measuring tank 10.
- the measuring tank is in contact with a scale 23.
- the measuring tank is further connected to a source of pressurized gas (not shown) via a pneumatic valve 19, a pressure regulator 21 and a conduit 24.
- the device further comprises a programmed electronic control unit able to control the different effectors of the device according to the invention in order to carry out the measurement sequences.
- the operator in charge of the test fills the oil tank 7 with the low level increased by a certain value (advantageously 0.5 liter).
- the engine is then installed on the test stand and the operator connects the oil sump to the device according to the invention by virtue of the quick coupling socket 13.
- the engine is then started up for a predetermined duration.
- the engine is stopped and the drain solenoid valve 9 controlled by the control unit opens allowing the lubricating liquid to fill the measuring tank 17.
- the whole is weighed by the balance 23 and this value is recorded.
- the pneumatic valve 19 opens and the lubricating liquid contained in the measuring tank 17 is brought into contact with air under pressure. This causes the oil to rise in the engine oil sump.
- the solenoid valve 9 is closed and the pneumatic valve 19 is positioned to allow the evacuation of the compressed air contained in the measuring tank 17.
- the motor is restarted for a predetermined time.
- the engine is stopped and a new weighing according to the preceding steps is carried out.
- the solenoid valve 9 is open and the oil flows through the gravity to the reservoir 17. A second measurement of the mass of the assembly is performed.
- the oil consumption of the engine is the mass difference between two successive measurements. After this second measurement, the oil is returned to the engine.
- Figure 2 shows an embodiment for performing a drain and automatic replenishment of the engine oil during testing.
- a fresh lubricant supply conduit 25 equipped with a valve 27 for closing it.
- the conduit 25 is connected at one end to a reservoir (not shown) filled with fresh lubricating liquid and at the other end to the measuring reservoir 17.
- Another drain conduit 29 of the oil sump communicates with the orifice 22 of the oil sump at one of its ends and with a used lubricant liquid recovery tank 33 at the other end thereof.
- This duct 29 is also equipped with a shut-off valve 31.
- the electronic control unit controls the opening of the emptying valve 31 and the liquid flows out of the casing. oil to the recovery tank 33.
- the drain valve 31 After complete emptying of the oil sump 7, the drain valve 31 is closed.
- the electronic control unit controls the opening of the supply valve 25 and the fresh lubricating liquid contained in the supply tank flows into the measuring tank 17. When the amount of fresh lubricating liquid is sufficient the valve supply 27 is closed.
- the pre-programmed control unit then controls the opening of the solenoid valve 9 and then the pneumatic valve 19.
- the lubricating liquid contained in the measuring tank 17 is brought into contact with air under pressure. This causes the oil to rise in the engine oil sump.
- the solenoid valve 9 is closed and The pneumatic valve is positioned to allow the evacuation of the compressed air contained in the measuring tank 17.
- the measurement, the emptying and the replenishment of fresh lubricating liquid are thus carried out without the intervention of an operator, which avoids the mobilization of a resource and authorizes the performance of a continuous test.
