MULTI-FUEL SYSTEM FOR PREPARATION OF FUEL GAS FOR FEEDING GAS INTERNAL COMBUSTION ENGINE Russian patent published in 2019 - IPC F02M21/02 F02M43/00 F02D19/02 F02B43/00 

FIELD: engines and pumps.

SUBSTANCE: invention can be used in fuel feed systems of gas internal combustion engines (ICE). Disclosed is a multi-fuel fuel preparation system for feeding gas ICE 600, comprising fuel tanks 100, regasification unit 200, mixing unit 400, comprising valves 300 and flow sensors, and control unit 700. In fuel tanks 100 separate storage of fuel components in liquefied condition is carried out: methane, ethane, propane and butane. Through control unit 700, the ratio in the fuel gas of the fuel components entering mixing unit 400 is controlled depending on the heat of combustion of the fuel gas required for the specific operating conditions of the engine.

EFFECT: proposed multi-fuel system allows to form optimal composition of fuel gas mixture from various fuel components with required energy properties for various operating modes of internal combustion engine.
