INTERNAL COMBUSTION ENGINE AND ITS CONTROL METHOD Russian patent published in 2011 - IPC F02B19/10 F02B33/22 F02D39/06 F02D39/08 

FIELD: engines and pumps.

SUBSTANCE: engine includes working cylinder with working piston and compressor cylinder with compressor piston, which is kinematically connected to working piston, and combustion chamber with ignition plug. Combustion chamber is connected. Engine is also equipped with air and fuel supply channels and two fuel supply devices. One of them is located in upper part of compressor cylinder and the other one is located in inlet air supply channel to combustion chamber. Engine is equipped with gas-distributing mechanism, inlet and outlet valves installed at inlets of combustion chamber of inlet and outlet channels, phase sensor and angular sensor of crankshaft, which are connected to engine control unit that is connected to accelerator, to fuel supply devices, to control module of throttle valve installed in air supply channel to compressor cylinder, and to mass air flow sensor installed in this channel. Fuel-air mixture is supplied to combustion chamber from compressor cylinder. At high loads and in full power condition there additionally supplied is fuel-air mixture to combustion chamber from its inlet channel, this supplying fuel to this channel. Injection of fuel-air mixture to combustion chamber from compressor cylinder is performed at compression stroke not later than 10° of turn of crankshaft of working piston to upper dead point. Fuel is supplied to inlet channel of combustion chamber through fuel supply device located in this channel during the filling stroke of working cylinder after the outlet valve is closed. Engine control method is described.

EFFECT: increasing engine power, reducing fuel flow and gas toxicity level.
