METHOD OF ICE CYLINDER SUPERCHARGING AND DEVICE TO THIS END Russian patent published in 2014 - IPC F02B25/00 F02B33/00 F02B75/32 F02F3/24 

FIELD: engines and pumps.

SUBSTANCE: proposed method comprises sucking atmospheric air via air duct in under-piston space at ICE compression stroke and shutting it off automatically at the start of working stroke. As pressure in said under-piston space is higher than that inside the piston the air is bypassed in said chamber unless the termination of working stroke. At the start of exhaust stroke, second portion of air is sucked in under-piston space. Chamber with aforesaid first air portion is automatically shut off to inject atomised fuel into said under-piston space while produced combustible mix is automatically forced via said chamber into the piston. As pressure in under-piston pace exceeds that in piston chamber the outlet therefrom is opened at the start of gas intake stroke. Both air portions at piston combustion chamber outlet and fuel evaporated therein Invention covers ICE running on said principle.

EFFECT: lower power consumption.
