The invention relates to the field of engine construction and can be used in motor units of internal combustion engines for controlling their operation.

There is a method of controlling operation of the internal combustion engine, based on listening to acoustic noise operation of the propulsion system and/or determining the change in the acceleration of movement of the moving base (vehicle) running the engine with the help of the vestibular apparatus operator (the driver of the vehicle) and the change in the flow rate of the hydrocarbon fuel to provide a given operator mode of operation of the engine [1]. The disadvantage of this method is low speed and large operator fatigue during operation of the internal combustion engine. In addition, the operation of the internal combustion engine is determined only given a narrow class (type) of a hydrocarbon fuel.

The closest known technical solution prototype is a method of controlling operation of the internal combustion engine by changing the gas mixture, which is characterized by the fact that form a flow of air and the flow of air nicotinebuy and hardened products obtained plazmaelektrohimicheskogo pyrolysis [2]. By changing the air-fuel mixture and its chemical activity with the carburetor and plazmaelektrohimicheskogo technology controls the operation of the internal combustion engine with different types of hydrocarbon fuel with forced spark ignition system and/or fuel equipment high pressure.

The disadvantage of the prototype is the low reliability of the control operation of the internal combustion engine, since the quantity and quality of prepared control the fuel mixture does not take into account the physical working condition of the propulsion system. Another disadvantage of the prototype lies in the complexity of the technical implementation due to the need for inclusion in the contour of the engine management system of forced spark ignition and/or fuel system high-pressure.

The aim of the invention is to increase the reliability of the control action changes the fuel mixture on the operation of the internal combustion engine due to the automatic correction of the composition and reactivity of the combustible mixture, depending on the mode of operation of the engine. Another object of the invention is to simplify the technical and fuel systems high pressure more than a simple technical implementation plazmaelektrohimicheskogo technology in-vessel processes of the internal combustion engine.

The invention consists in that, in addition to the known and common operations, namely the formation of air flow and air temperature plasma, activation of the hydrocarbon fuel formed by the flow of air temperature plasma and hardening of the products obtained plazmaelektrohimicheskogo pyrolysis, a new set of operations, which is characterized by the fact that regulate the intensity of the previously generated air flow, adjusted direct air flow and the flow of previously hardened products plazmaelektrohimicheskogo pyrolysis in the waiting area and mixing engine for mixing, compress the mixture in the combustion chamber for ignition, fix in each cycle of operation of the engine, its physical state, for example, the change in acceleration of the crankshaft and/or the pressure in the combustion chamber and/or changes in the acoustic oscillations of the fuel combustion process, measure the interval desync and reduced in subsequent cycles of operation of the engine measured misalignment fixed physical conditions of the engine by changing the air-fuel mixture and its chemical activity.

, upravlyaut adjusted the air flow and the flow of previously hardened products plazmaelektrohimicheskogo pyrolysis in the waiting area and mixing engine for mixing, compress the mixture in the combustion chamber for ignition, fix in each cycle of operation of the engine, its physical state, for example, the change in acceleration of the crankshaft and/or the pressure in the combustion chamber and/or changes in the acoustic oscillations of the fuel combustion process, measure the interval desync and reduced in subsequent cycles of operation of the engine measured misalignment fixed physical conditions of the engine by changing the air-fuel mixture and its chemical activity, to simplify the technical implementation and to improve the reliability of the control action changes the fuel mixture on the operation of the internal combustion engine due to the automatic correction of the composition and reactivity of the combustible mixture, depending on the mode of operation of the engine.

Functional diagram of an example implementation of the proposed method controls the internal combustion engine shown in the drawing, showing: 1 - the internal combustion engine; 2 - coolant region is the unit of electric power; 6 - control the flow of electrical energy; 7 - generator of low-temperature plasma; 8 plasma - chemical reactor; 9 - block hardening products plazmaelektrohimicheskogo pyrolysis of hydrocarbon fuel (block reduce the recombination rate of chemically active particles); 10 - air supply system; 11 - airflow switch; 12 - the Executive unit of the controller unit of hardening; 13 - air throttle valve; 14 - supply of hydrocarbon fuel; 15 - regulator fuel consumption; 16 controller; 17 - block input (primary) data; 18 - sensor unit; 19 - job element (unit) operation mode of the engine by the driver (operator).

The drawing shows that in the initial state of the internal combustion engine 1 with its scope expectations and mixing 2 is connected with the respective n power cylinders of the cylinder block 3. The first input plazmaelektrohimicheskogo generator 4 is connected to the output of the power supply 5 through the flow regulator electrical energy 6 and connected in series between a low-temperature plasma generator 7, plasmachemical reactor 8 and the block hardening 9 to the entrance area expectations and mixing 2. The output of the system air supply 10 centralnego device controller 12 is connected to the second input unit of hardening 9. Air throttle valve 13 is included between the output of the system air supply 10 and a second input area expectations and mixing 2. The output delivery system hydrocarbon fuel 14 through the controller 15 is connected to a second input of the plasma-chemical reactor 8. The outputs of the controller 16 is connected to the control inputs of the respective regulators 6, 11-13 and 15. The output unit 17 is connected to the input of the input (primary) data controller 16. The information inputs of the controller 16 is connected through the sensor unit 18 to the outputs of the corresponding element 19 set mode and the outputs of the internal combustion engine 1.

An example of the technical implementation of the proposed method controls the internal combustion engine works as follows.

The air flow from the output of the system air supply 10 through the controller 11 is supplied to one of inputs of the generator 7, which is formed of low-temperature plasma, which implements the well-known operation of forming the air flow and air temperature plasma. The flow of air from the air system 10 for generating the plasma does not exceed (1-2%). Voltage for generating plasma is supplied from the output unit of the electric power supply 5 via the s 7 is directed to the plasma-chemical reactor 8, where known, the operation of activating the hydrocarbon fuel from the fuel system 14 via the controller 15 is supplied into the reactor 8. To exclude subsequent unauthorized ignition of the obtained activated hydrocarbon fuel his hardened known in the prototype technique using block hardening 9.

Previously generated air flow from the outlet of the air system 10 serves to adjust the air throttle valve 13 and send it to the waiting area and mixing 2 of the internal combustion engine 1, to which are invited to submit previously obtained hardened products plazmaelektrohimicheskogo pyrolysis output unit 9 hardening. In the field of expectations and mixing 2 of the engine 1 is implemented, the proposed operation of the mixing of air and quenched pyrolysis products. The resulting mixture is compressed in the combustion chamber prior to its ignition. The moment of ignition of the combustible mixture set it formed in unit 2 structure and chemical activity.

He further suggests that in each cycle of engine operation to fix his physical condition, for example, by measuring the variations of the acceleration of rotation of the crankshaft and/or Dawla operation of fixing the physical parameters of the engine is implemented using the sensor unit 18, output signals are transmitted to the information inputs of the controller 16, which is also the dimension of inter-cycle interval desync engine operation.

The measured misalignment is fixed physical conditions of the engine in each cycle of its operation is reduced to zero (negligible) value by changing the air-fuel mixture and its chemical activity. For this purpose, the control signals from the output of the controller 16 impinges on the respective flow regulators electrical energy 6, air 11 and 13, the fuel 15 and the degree of hardening 12 given the original (primary) data in block 17 of the original data.

When changing the operation mode of the engine element 19 the resulting misalignment of its fixed parameters are automatically eliminated, thereby increasing the accuracy of control of the internal combustion engine.

Industrial applicability of the proposed method controls the internal combustion engine is achieved by the fact that the proposed new operations are implemented standard functional blocks, namely the sensor 18, the controller 16 and regulators 6, 11-13 and 15, which are used for its intended known for the technical documentation and testing of prototypes of the engine, in cooperation with JSC "AVTOVAZ" and DOAO "IZHMASH-AVTO".

The positive effect from the use of the invention is that the increased approximately two times the reliability of control on the internal combustion engine by increasing the flow control information from sensors in the feedback circuit to control the operation of the internal combustion engine.

In addition, simplified technical implementation of business process management of the internal combustion engine due to the replacement of complex and expensive fuel system high pressure and/or system forced the spark plugs on a more simple technical implementation plazmaelektrohimicheskogo technology in-vessel processes of the internal combustion engine.
