HIGH PRECISION CONTINUOUS SUPPLY OF GASEOUS FUEL FOR HIGH DYNAMIC POWER RANGES Russian patent published in 2018 - IPC F02M21/02 

FIELD: engines and pumps.

SUBSTANCE: invention can be used in gas fuel supply systems for internal combustion engines (ICE). A device for high precision adjustment of gaseous fuel flow for internal combustion engine with spark ignition is provided and includes a single block of valves comprising a first stage for gaseous fuel flow adjustment with electric motor of the first stage drive and a second stage for gaseous fuel flow adjustment with electric motor of the second stage drive. The first and second stages for adjusting the flow of gaseous fuel comprise means for controlling their drives connected to a controller also arranged in the valve block. The controller is programmed to coordinate the operation of the first flow control stage and the second flow control stage by controlling their drives to achieve required consumption of gaseous fuel through the proposed adjustment device.

EFFECT: device for implementation of the method improves fuel supply dynamics and increases the efficiency factor.
