Description

The proposal relates to engine building, namely to control devices for power plants of internal combustion engines in order to improve throttle response. The system allows improving the throttle response of the tank power plant by additionally supplying high-quality atomized fuel (activator) to the diesel intake manifold. Improving the quality of fuel atomization is achieved by installing nozzles in the intake manifold with a device for vortex aerodynamic mixing of fuel with air (VD Dudyshev, Vortex fuel injector / VD Dudyshev: utility model patent RU 140649 F02D 11/10, F02M 61/02, publ. 05.20.2014).

A device for increasing the throttle response of a power plant of a tank (Moskalev BC Device for increasing the throttle response of a power plant of a tank // BC Moskalev: patent for invention RU 2176742 F02D 23/02, publ. 10.12.2001), comprising: a turbo-piston diesel engine with an intake manifold, air an engine starting system equipped with an air cylinder pneumatically connected to a reduction gear, an electro-pneumatic valve, an electrically connected boost pressure sensor and a fuel pedal.

The disadvantage of this design is that to improve the throttle response of the tank, a large air flow rate is allowed from the tank’s tank air system, which is the main system for starting the engine of the combat vehicle. From this follows the conclusion about the possible negative impact of such a design on the combat readiness of the machine. However, it should be noted the low efficiency of the method of increasing engine throttle response by supplying additional air, due to the excessively high air flow and very small effect.

The system for supplying a hydrocarbon activator to a diesel engine is also known (Matveev V.A., Rachkin V.A., Ryblov M.V., Ukhanov A.P. System for supplying a hydrocarbon activator to a diesel engine / V.A. Matveev, V.A. Rachkin, M.V. Ryblov, A.P. Ukhanov: patent for utility model RU 72018 F02M 43, F02D 19/12, published March 27, 2018, Bull. No. 9), comprising: an electromagnetic nozzle located in the diesel inlet pipe and communicated by a connecting pipe with an electric pump, engine speed sensors and the position of the rail of the high pressure fuel pump, ele a ctron control unit that is electrically connected to the power source and placed through the sensors of the coolant temperature and the acceptable voltage reduction of the on-board network with the power source, while there is an ultrasonic oscillator with a frequency of 20 to 100 kHz, electrically connected to the power source and located in close proximity from the latter.

The disadvantage of this design is the rather weak effect of the emitter of ultrasonic vibrations on the quality of atomization of fuel. It should also be noted that the supply of additional fuel (activator) leads to some substitution in the fresh charge of part of the air with fuel, which leads to a decrease in the coefficient of excess air, and hence the power, fuel, economic, environmental indicators and overall efficiency of the proposed system.

A device for increasing the throttle response of a power plant of the tank (Moskalev BC A device for increasing the throttle response of a power plant of a tank // BC Moskalev: patent for invention RU 2176742 F02D 23/02, published 10.12.2001), is the closest to that proposed in the application by its technical nature and adopted as a prototype.

The utility model solves the problem of improving the throttle response of a tank power plant.

The solution to this problem is achieved by the fact that vortex electromagnetic nozzles are installed in the intake manifolds of the power plant, which supply additional, high-quality atomized fuel with air to the intake manifolds of the diesel engine under conditions requiring increased power of the tank power plant. The use of nozzles with a device for vortex aerodynamic mixing of fuel and air allows to improve the quality of fuel atomization (Dudyshev V.D. Vortex fuel nozzle / V.D.Dudyshev: utility model patent RU 140649 F02D 11/10, F02M 61/02, publ. 20.05 .2014). The air supply of the electromagnetic nozzles is also supplied from the tank of the tank’s air system, however, it is characterized by very limited air consumption compared to the prototype.

An analysis of the proposed solution and the known ones allows us to conclude that it meets the patentability conditions of the utility model.

The proposal is illustrated in the drawing, which shows a schematic diagram of a system for short-term boosting the power plant of the tank.

The proposed system for short-term boosting the power plant of the tank contains: an air engine starting system equipped with air cylinders 1, an air filter 2, a reduction gear 3, pipelines 4, 10, an electro-pneumatic valve 5, an electric fuel pump 6, intake manifolds 7, a turbo piston internal combustion engine 8, vortex electromagnetic nozzles 9, electronic control unit 11, switch 12, microswitch 13 and fuel pedal 14.

The proposed system for short-term boosting the power plant of the tank works as follows. When the engine is operating under low load and idle conditions, as well as when the tank moves at a limited speed (without enemy action), the proposed system is in the off state. In the event of a possible collision with the enemy or deterioration of road and soil conditions requiring an increase in power above the established engine characteristic, the driver mechanic turns on the switch 12, thereby bringing the short-term boost system of the power plant of the tank into working condition. Acting on the fuel supply pedal 14, the driver closes the microswitch 13 located under it, from which the command to the electronic control unit 11 follows. Next, the signal from the electronic control unit 11 is received:

to the electro-pneumatic valve 5, providing its opening and air supply under pressure through pipelines 10 to the vortex electromagnetic nozzles 9. The air for supplying the vortex electromagnetic nozzles 9 is contained in air cylinders 1, the necessary pressure in the air network is provided by a reduction gear 3;

on an electric fuel pump 6, ensuring its operation and, accordingly, supplying fuel with vortex electromagnetic nozzles 9;

to the vortex electromagnetic nozzles 9, providing their opening and feeding a portion of the air-fuel mixture into the intake manifolds 7 of the turbo-piston internal combustion engine 8, while the necessary increase in the power of the power plant occurs.

If there is no need for further tank movement in forced mode, the driver releases the fuel pedal 14, the microswitch 13 located under it is turned off, thereby signaling the electronic control unit 11 to stop supplying an additional portion of the air-fuel mixture to the intake manifolds 7 of the turbo-piston internal combustion engine 8 .

The consumed amount of air from the air cylinders 1 will be replenished with a standard engine compressor (not shown).

Compared with the prototype, the proposed system for short-term boosting the power plant of the tank provides better engine throttle response.
