METHOD OF OPERATING PISTON INTERNAL COMBUSTION ENGINE AND PISTON INTERNAL COMBUSTION ENGINE Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: fresh air is fed to main combustion chamber 3 through passage 6 and valve 5. Gasoline-air mixture is fed to auxiliary combustion chamber, which is positioned in the cylinder head 1, from carburetor 8 through passage 7 and valve 4. The contents of both the chambers is compressed by piston 12 in cylinder 13, the gasoline-air mixture in auxiliary combustion chamber is ignited with spark plug 9, and, at the instant of spreading flame over tongue passageway 11 to main combustion chamber 3, burning Diesel fuel is injected in main combustion chamber 3 through nozzle 10 whose outlet is opposite to the inlet of tongue passageway 11. Next the working stroke of piston 12 is performed. EFFECT: enhanced efficiency. 2 cl, 1 dwg
