ELECTRONIC SYSTEM FOR FEEDING GAS FUEL TO SUPERCHARGED DIESEL ENGINE AND COOLING SUPERCHARGING AIR Russian patent published in 2017 - IPC F02M43/00 F02M21/02 F02D19/06 

FIELD: engine devices and pumps.

SUBSTANCE: electronic gas fuel supply system in an internal combustion engine (ICE) is proposed with supercharging and cooling of supercharging air, containing a frame of gas nozzles 10, gas ducts, differential two-stage gas reducer 15, an electromagnetic gas valve 23 with a filter element, a knock sensor 21, a crankshaft speed sensor 22, a gas fuel temperature sensor 11, an exhaust gas temperature sensor 6, an electronic control unit 20, a gas system switch 26 with sound-light indicator, supercharging air cooling radiator 7. The system has a supercharging air temperature sensor 2, supercharging air and gas fuel pressure difference sensor 9, a step controller 16 of the cooling fluid flow rate through a communication channel of the supercharging air cooling radiator 7 with the differential two-stage gas reducer 15.

EFFECT: increase efficiency of gas fuel supply to diesel engine and increase of engine cylinder filling factor.
