ELECTRONIC GAS SUPPLY PRESSURE CONTROL, NAMELY OF METHANE OR HYDROGEN, TO INTERNAL COMBUSTION ENGINE, AND GAS SUPPLY SYSTEM CONTAINING SUCH DEVICE Russian patent published in 2011 - IPC F02M21/00 F02B43/00 F02D19/02 

FIELD: engines and pumps.

SUBSTANCE: gas supply system, namely for supply of methane or hydrogen, to internal combustion engine includes multiple injectors with electromagnetic control, which are connected to various engine cylinders, distributing manifold or gas ramp, which are connected to injectors; gas supply tank to distributing manifold, in which compressed gas is accumulated, and pressure reducing valve. Electromagnetic control valve includes inlet hole connected to fuel tank, outlet hole connected to auxiliary inlet hole of pressure-reducing valve, as well as to distributing manifold; movable armature control solenoid that controls the connection between inlet holes and outlet hole of electromagnetic control valve to provide the specified gas pressure reduction in the channel from inlet hole to outlet hole of electromagnetic control valve. In addition, gas supply system includes electronic solenoid control device of electromagnetic control valve. Pressure reducing valve and electromagnetic control valve are combined in housing of common electronic pressure control. In the housing there is inlet hole for gas supplied from fuel tank; outlet hole for gas that is supplied to distributing manifold or gas ramp; connecting channel between inlet hole and pressure reducing valve; connecting channel between inlet hole and electromagnetic control valve; connecting channel between electromagnetic control valve and pressure reducing valve; connecting channel between electromagnetic control valve and outlet hole, and connecting channel between pressure reducing valve and outlet hole. In addition, the device includes electronic solenoid control module of electromagnetic control valve. Electronic pressure control for gas supply system, namely for supply of methane or hydrogen, to internal combustion engine has housing. In housing there combined is pressure reducing valve of gas supplied from fuel tank to the value required for gas supply to distributing manifold or gas ramp, and electromagnetic control valve having the possibility of generating pressure control signal on which pressure reduction degree depends, which is performed by means of pressure reducing valve, as well as connecting channels between the above valves and between each of the above valves and inlet hole and outlet hole of the device. In addition, the device includes electronic control module for control of electromagnetic control valve.

EFFECT: invention allows improving the proposed system, namely owing to simplifying and improving its components.
