INTERNAL COMBUSTION ENGINE AND CONTROL METHOD THEREOF Russian patent published in 2020 - IPC F02B33/16 F02B33/22 F02B13/06 

FIELD: machine building.

SUBSTANCE: group of inventions relates to internal combustion engines. Proposed invention comprises working cylinder with working piston articulated with compressor piston with interlocked compressor piston with a cylinder and combustion chamber with ignition plug. Around the combustion chamber there is an annular channel connected to it by small channels. Circular channel is connected with fuel-air mix feed channel from compressor cylinder. Around the combustion chamber there is a second annular channel connected to the working cylinder by two or more channels, which are arranged evenly along circumference of the annular channel. Axes of these channels are inclined towards the axis of the working cylinder. Second annular channel is connected to the compressor cylinder by an additional channel equipped with a valve with a controlled drive and a leaf check valve. At power operating mode simultaneously with supply of fuel-air mix to combustion chamber valve with controlled drive is opened and, via additional channel, second circular channel and channels connecting it with working cylinder, fuel assembly is supplied to working cylinder from compressor cylinder. Duration of fuel assembly feeding into working cylinder during engine operation cycle is controlled, and in idle and low-load conditions fuel supply to working cylinder is stopped.

EFFECT: technical result is higher stability of engine operation.
