Description

one

This invention relates to engine-building and can be used in gas engines for internal combustion operating on hydrogen.

Gas engines for internal combustion are known, comprising a combustion chamber connected through a mixer to an air inlet pipe in which a throttle provided with a control member is placed, and to a duct exiting a gas generator with an energy-accumulating substance equipped with a main line for supplying water and an accelerator pedal G.

In the known engines for controlling the ratio of air / hydrogen entering the combustion chamber, is carried out using a tank in which the produced hydrogen is accumulated. However, tanks with hydrogen, which is explosive, are difficult to use on the vehicle.

The object of the invention is to create. such an engine in which hydrogen would be metered into the combustion chamber without prior accumulation.

The purpose of the invention is to provide explosion safety.

This goal is achieved by the fact that the control unit is installed interlocked with the accelerator pedal, and the control unit is designed as a pressure sensor placed in the channel, and the control unit can be designed as a pump with a device for changing the stroke of the plunger, and the gas generator to be connected to a source of energy-accumulating substance through a pipeline in which a metering device is installed, interlocked with the accelerator pedal and, preferably made in the form of an auger, is supplied nnogo device changes its rotations; between the accelerator pedal and devices dl change the stroke of the plunger and change the speed of the auger can be

a corrector is connected to the pressure sensor in the channel.

The drawing shows a diagram of the implementation of the gas engine.

Claims (4)

The gas engine of the internal combustion contains a combustion chamber 1, connected through a mixer 2 with the nozzle 3 sfia. supply air, in which the choke 4 is located, and with channel 5 leaving the gas generator 6. Channel 5 is equipped with a shut-off element 7. Throttle 4 is equipped with a control body 8 made in the form of a pressure sensor placed in channel 5 Gas generator 6 through the shaft 9 is connected with a tank 10, in which zodka 11 is located, and through conduit 12 - with source 13, in which there is an energy-accumulating substance 14. Regulatory body 15 is installed in line 9, and metering device 16 is installed in pipeline 12. The control body 15 and the dosage device 16 are interlocked with the accelerator pedal 17. Preferably, the control member 15 is configured as 18 with a device 19 for changing the stroke of the plunger 20, which may be an oblique washer 21 connected via cables 22 and 23 to the pedal 17 of the accelerator. Preferably, the dosing device is designed as an auger 24 equipped with a device 25 for changing it revolutions, which is connected via the 26 to 23 of the accelerator. Accelerator pedal 17 and devices 19 and 25 are fitted with an equalizer 27 connected to pressure sensor 28 in channel 5. Pressure sensor 28 is connected to channel 5 by highway 29. Corrector 27 is ying with the possibility to vary the length of the rod 23. The gas generator 6 is connected with the container 30 for SRB ra nonvolatile reaction products. When operating at idle (accelerator pedal 17 is not pressed), the spit washer 21 and device 25 are in the position in which they supply water 11 and energy-energy Kug / 1st agent 14 to the gas generator 6 in sufficient quantities to idle the engine. At the same time, in the gas generator 6, the idling pressure is established. The hydrogen produced in the reaction of water and the energy-accumulating substance is fed through channel 5 to mixer 2. In mixer 2, hydrogen is mixed with air, a station :: a0 from pipe 3, and the hydrogen-air mixture enters the combustion chamber 1 for combustion. The amount of air entering from the nozzle 3 into the mixer 2 is controlled by the throttle 4, controlled by the control member 8, depending on the pressure in channel 5. To adjust the coefficient of excess-air in the channel 5, a stop member 7 is provided, which increases or decreases the channel cross section 5. When reducing the flow area, the pressure in the gas generator 6 and the channel 5 increases, and the control body 8 increases the amount of air entering the mixer 2. To decrease the amount of air supplied to the mixer 2, by a shut-off device 7, the flow area of the channel 5 is increased. When pressing the accelerator pedal 17, the tractor ha 23 increases the angle of inclination of the slanting baisha 21 and the screw speed 24 through the brake 26. In this case, the water supply and energy storage substance to the gas generator 6 increases, and the release of hydrogen, and hence its pressure, increases. In a mixture of bodies b; -2 more hydrogen is supplied. The increased hydrogen pressure in channel 5 is sensed by the pressure sensor of control body 8. The control body 8 opens the throttle 4, and the yolley air flow enters the mixer 2 when the excess air ratio specified by the shut-off body 7 is stored. In the case of an increase in pressure in the gas generator 6 and channel 5 above the permissible pressure sensor 28, it acts on the correction device 27, which lengthens tu 23, which leads to a decrease in the angle of inclination ko. washers 21 and a decrease in the rotation speed of 24 and, accordingly, to a reduction in the supply of water and energy to the gas generator to the gas generator 6. Adjustment of the idling speed is performed by tilting the oblique washer 21 and changing the position of the device 25. The device 25 and the oblique washer 21 can also be adjusted the ratio of water / energy storage substance, feeding in the engine, for example, water vapor. Claim 1.
