The invention relates to diagnostics of liquid media, as well as automotive diagnosticheskoi technique and can be used both by companies and by drivers of cars for diagnostics during operation of the vehicle.

There are many devices for determining the characteristics of automobiling oil. As well known device for monitoring impurities in the oil [1] using capacitive sensors, which specifies only one capacitive characteristic of the oil, and therefore has a low accuracy assessment of the performance of the oil. Known self-calibrating capacitive transducer [2], based on the contactless determination of liquid media using ultrasonic vibrations, the disadvantage of this approach is that the description is given only in one indicator. A device for measuring emulsified water in the oil [3], including the electrical characteristic due to the transmission oil on the device where you installed the electrodes, but this unit describes the oil one conductivity. Also has a device for measuring conductivity of liquid media [4], where also used to characterize a single measure. There is a device for measuring conductivity of substances [5], which uses induction EF is known in the characterization of liquid media, but the disadvantage of this device that it uses to characterize few indicators. A device for measurement of liquid media [6], which has a complex mechanical design, and also has the disadvantage of limited information on the characteristics of the liquid medium. Known capillary microviscometer [7], which uses a syringe and time of expiration of the liquid environment is characterized by a liquid medium, but this unit assesses only one environment parameter. Known submersible viscometer [8], but this device gives only limited information about the liquid medium. There are convenient contactless electrical capacitive proximity sensors [9], but they are not very informative.

The prototype of the claimed device is a device for studies of saliva [10], which includes a housing with two cylinders, made of dielectric material, in cylinders installed capacitive, inductive, electrical and piezoelectric sensors. Positive in this device is that the information about the liquid environment comes from multiple sources and is more complete than from one or two sensors that characterize the state of a liquid medium. The disadvantage is that this device is not adapted for assessment of motor is about oil, and there is no sensor to determine the viscosity of the liquid under study.

The device operates as follows. Before use or after use, the device is washed with gasoline, alcohol or other solvent, if the device before using it was washed and stored in a sealed package, tomono be used immediately. The device must be made of dielectric material and is resistant to solvents. Before buying motor oil of the driver device includes a switch 30 (Fig 1, 2, 3), then the buttons 32 and 33 picks up on the indicator 31 days and other characteristics of the external environmental factors: atmospheric pressure, humidity, and so forth, if they are not at hand, then this data is neglected, then include the appropriate command, the temperature of the device automatically enters with a temperature-sensitive element 22 and is transmitted to the integrating device, then picks up one of the grades of oil that are stored in the memory 39 of the device (figure 5). The device may have data in the memory of different types of motor oils, or the driver can start the data branded oil. When the indicator 31 of the name of the oil, the motorist opens the lid of the canister purchased oil and through the opening in the canister starts acting cylinder 11 with the tube 14 into the oil and, holding the base 6, pulls him to a stop, the oil from the fuel enters the device. He then pulls the lower part of the device of the cans of oil, the indicator lights up ready to work, then the driver moves the latch 7 and raises the base until it stops, while the discharge tube 14 is located above the hole is a tie in the canister or container, where will blend in the oil. The device should be held upright and wait until the oil is all drained through the discharge tube 14 back into the canister, or other container. After the oil glass on the display 31 will receive the information, if the characteristics of the oil in the canister coincided with the characteristics of the oil, requested from the memory 39, a message appears stating that the oil is the same. If oil characteristics do not coincide with the characteristics requested from the memory 39 of the oil (figure 5), the indicator will show that the oil has not the same characteristics, and the driver with the buttons 32 and 33 may see what characteristics of purchased oil is not the same. If the driver has acquired oil, analogues of which was not in memory 39, then he gets in the memory 39 of the buttons 32 and 33 data characterizing bought the oil. If the oil does not have the same characteristics, the driver can not to buy it. Next, after a certain number of kilometers, depending on the age and deterioration of the vehicle, the driver can check the condition of the oil at the moment: he wears a connecting tube, for example from a medical dropper, and at idle and the engine has cooled down through the hole for the oil dipstick sucks the oil from the engine of the machine or other automatic node is Biel in the device, before this driver, if necessary, washes device includes gaining code that oil which is filled in the host vehicle. Then, as usual when checking, fixing the device in a vertical position, the exhaust tube 14 down over the tank to drain, removes the lock 7, raises the base 6 to the stop and drain oil from unit. If the characteristics differ sharply from purchased oils, in sites where there is no filter, the oil should be changed, and the engine driver can first change the oil filter, and then after running the engine again to check the oil and if the oil when you put the new filter showed dramatically altered characteristics, the oil should be changed and the chassis of the vehicle is subject to diagnosis and preventive measures.

The principle of operation of the device is as follows: when the oil is sucked, through the inlet channel 27 (2) oil due to the sparse pressure generated in the cylinder 2 below the piston 3 enters the device. As the internal volume 26 significantly more internal volume from the end of the inlet tube 14 to the hole 17, the oil can go in volume 26 of the cylinder 2. In this lock 7 holds the position of the piston 3 in such a position that the opening 8 is closed by the piston 3 and the cylinder 2, a vacuum and oil from the device does not. After TRG is how the device is switched on and the oil is in the device this oil should be above the top of the cavity 15, where will be the appropriate signal from the photosensitive device 21 via the amplifier and the switch 37 (figure 5) in the integrating device 38, which sends the command to the indicator 31 that the device is ready to work. When integrating this device gives a command in various modes, for example sequentially, includes electric sensors 23, 24, capacitive 34 and 35, the piezoelectric 25 and inductive 29, thermosensitive 22 and the data from the photosensitive elements 21. After the characteristics of those sensors are received at the integrating device 38 and the memory 39, the indicator 31 receives the signal that the device is ready for further research. Then proceed to the determination of the viscosity, which is determined by the flow rate of oil from the standardized volume through the same hole: to do this, remove the retainer 7 and the retractable base 6 to stop, after which the piston 3 rises above the hole 8 and into the interior of the cylinder 2 through the opening 10 and the duct 9 will begin to enter the air. The device is in a vertical position, and as soon as the oil falls below the light source 20, in the upper cavity 15 is included evaluation of the viscosity characteristics speed coincidence of oil between the cylinders 11 and 12 in the space 28 and inside a small Qili the DRA 36. Further data can be analyzed with the movement of the oil, while oil moves down, can consistently include other sensors for measuring characteristics of the oils in the movement. So electric sensor can work on the determination of conductivity, and also to estimate the amplitude and spectral characteristics of oil - when the current electrode 23 serves a range of a certain frequency and amplitude, and sensitive 24 is removed certain characteristic changes. When the oil reaches the bottom of the cavity 16 and the photosensitive element 21 will signal that the oil has passed this mark, the integrating device 38 will proceed with the analysis of the information on viscosity. Temperature-sensitive sensor installed at the bottom of the cavity 16, so that it was more oil and therefore more information will be on the oil temperature, as an integrating device must make allowances for the different source parameters, including temperature, for a more accurate analysis of the characteristics of the oil. Next, the integrating device 38 compares the characteristics of the oil from the memory 39 and which is tested and gives information to the driver.
