Description

The invention relates to a measuring technique in the field of engine construction for determining operational performance during operation, diagnosis, testing. In particular, the invention is used to determine the time of the engine when monitoring the service life.

A known system for monitoring and recording the performance of a motor vehicle [1], which includes a connected total fuel consumption meter, a total running time counter and a total counter of special equipment, a unit for the type of road surface connected to the registration unit, allowing to determine the operational performance during operation , as well as monitor the timing of operation.

The disadvantages of the known system are the complexity of the design, the inability to obtain accurate information about the time of the engine in various operating modes, for example at idle, with overloads.

A device for recording the time of engine operation [2], containing a sensor, a first element, a low speed counter, a nominal rotation speed counter and a counter for changing the direction of shaft rotation, the first and second elements, the second and third elements, the shaft rotation direction block are entered. motor and motor shaft rotational speed, and the sensor is made in the form of a magnet mounted on a rotating engine part, and a fixed winding.

The disadvantages of the known design are its susceptibility to electromagnetic interference, the possibility of blocking the operation of the counter by installing a permanent magnet near the winding of the counter, which distorts information about the time of engine operation.

As a prototype for the method, the running time counter of the running system [3] is adopted, which operates according to the method of determining the operating time, contains a device that records the shaft rotation speed with a sensor, a control trigger, a sensor mounted on the driving wheel and connected through a shaper of rectangular pulses to a control trigger and a delay counter connected to the reset input of a control trigger connected to a clock consisting of interconnected non-volatile electromechanical counters connected to an indicator .

A disadvantage of the known construction is the impossibility of obtaining true information about the running time of the chassis system, since the sensor is turned on when the drive wheel is triggered, this does not mean that the others work, for example, when it slips. The inability to determine the time of the system under different load conditions. This does not provide a complete picture for determining the residual work resource.

As a prototype for the device, a device is adopted for determining the time of engine operation [4], which contains a sensor, a counter, an analysis unit and an indicator made in the form of two functionally independent blocks placed in separate housings - an accumulator of operating time, including a sensor and a counter, and a reader operation time, containing the analysis unit and the indicator, while the counter is equipped with an independent power source and the first communication unit, the sensor is installed with the ability to interact with the counter and is designed as a transducer Pressure is connected to the oil line of the engine lubrication system, and the analysis unit is connected to the indicator and equipped with a request device and a second communication unit, configured to be periodically connected to the first communication unit.

The disadvantage of the prototype is the same as in the analogue of [1], the impossibility of determining the time of operation of the system under different load conditions. This does not provide a complete picture for determining the residual service life of the engine.

The objective of the invention is to improve the accuracy of measurement, increase the objectivity of resource assessment due to the difficulty of unauthorized intervention in the simplification of measurements, the creation of conditions for obtaining not conditional, but real data.

The task of the method is solved in that in a known method for determining the operating time of the internal combustion engine, in which the operating parameters of a separate unit or engine system are recorded and, subsequently, the engine operating time is determined from the registered value, according to the invention, a time counter is used, which includes fuel consumption sensor and turn off at the end of his work.

The task is also solved by the fact that they use more than one time counter to determine the operating time of the internal combustion engine in various modes depending on the fuel consumption rate, and when the fuel consumption rate changes, the counter corresponding to the consumption rate is switched off and all the meters are turned off when the fuel consumption stops.

The task for the device for determining the operating time of the internal combustion engine is solved by the fact that in the known device comprising a sensor, an operation time counter, an analyzer and an indicator according to the invention, the operating time counter is connected to the analyzer via a key, and the device contains at least two time counters for determining time of operation of the internal combustion engine in various modes depending on the rate of fuel consumption.

The task is also solved by the fact that the device contains three counters for determining engine operation in idle mode, nominal operation and overload.

The invention is illustrated in the drawing.

The drawing shows a diagram of the device for implementing the method for determining the time of operation of an internal combustion engine.

The device for determining the operating time of the internal combustion engine consists of a fuel consumption sensor 1, which is part of the fuel supply system 2 of the internal combustion engine 3. Fuel consumption sensor 1 is connected to the fuel consumption rate analyzer 4, which in turn is connected to clock 5 and controls key 6 Key 6 can be made in the form of a switch, which, depending on the state of the analyzer 4, sends a stream of pulses from clock 5 to one of the counters 7 through 10. The states of the counters can be monitored using the indicator eleven.

The device works as follows. When the engine 3 is turned on, fuel begins to flow and the fuel consumption sensor 1 starts operating. Analyzer 4 determines the value of the fuel consumption speed, which is different from zero, and turns on key 6. In the simplest version, a single counter 7 starts counting the fuel consumption sensor 1 operation time, which will be considered , as the operating time of the internal combustion engine 3. The key 6 will be open, and the time pulses from hours 5 will flow into counter 7 until the engine 3 stops. Counter 7 can be performed mechanically, electrically or electronic. But in any case, he should be able to constantly store the accumulated information. A more complex use of the invention involves the operation of several meters. At the same time, depending on the rate of fuel consumption, the analyzer 4 can switch pulses from the clock 5 to the counter corresponding to low fuel consumption, for example 7, the nominal speed of fuel consumption to the counter 8 using a key or switch 6; 9, with other possible modes - to the counter N. The state of all the counters can be monitored using the indicator 11, switching channels.

This embodiment of the method of determining the operating time of the internal combustion engine and the device for its implementation allows to improve the measurement accuracy, improve the objectivity of the resource assessment, creates conditions for obtaining real data. Simplification of the device allows you to increase savings through the control of the vehicle, the timely implementation of maintenance and repair of the vehicle.

At present, development work has been completed and prototypes manufactured.
