INTERNAL-COMBUSTION ENGINE SUPERCHARGING DEVICE

WIPO Patent Application WO/2017/149803

A1

[Problem] In internal-combustion engine supercharging devices comprising a supercharging means provided with an air flow rate amplifier which performs supercharging in a driving flow, two driving flow supply means for supplying driving flows to the supercharging means, and a fluid control means for controlling the pressure and/or flow rate of the two driving flows, it is difficult to mix the two driving flows using an accurate mixing ratio by controlling the two driving flows using the respective fluid control means, and it is consequently difficult to perform appropriate supercharging of premixed gas such as fuel, which is the driving flow, and this gives rise to problems such as that, if the pressure differential between the two driving flows is large, backflow between the driving flows may occur. [Solution] In this internal-combustion engine supercharging device, by providing the fluid control means of the internal-combustion engine with a pump type mixer comprising positive displacement pumps provided in both fluid passages and a rotation control means interlocking the two pumps, it is possible for a mixing ratio obtained by controlling respective driving flow supply pressures and a supercharging pressure obtained by means of the rotation control performed by the rotation control means to be controlled accurately.
