INTERNAL COMBUSTION ENGINE OPERATION METHOD Russian patent published in 2001 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: proposed method includes intake stroke of fuel-air mixture components into main combustion chamber and ignition chamber, compression stroke of fuel-air mixture simultaneously in main combustion chamber and ignition chamber, insulation of ignition chamber from main combustion chamber by overlapping connecting hole by means of flat gate and subsequent ignition of fuel-air mixture in ignition chamber at end of compression stroke. After complete combustion of fuel in ignition chamber at constant volume, high-temperature gas jet is introduced into main combustion chamber by shifting flat gate into space of main combustion chamber in parallel and along axis of connecting hole through distance equal to 0.9-1.5 of radial size of connecting hole during period of time not exceeding 0.1 μs. Amount of fuel fed into ignition chamber is chosen so that value of pressure of high-temperature combustion products in ignition chamber should exceed, not less than five times, value of pressure of fuel-air mixture in main chamber at moment of introduction of high- temperature gas jet. Then stroke of expansion of fuel-air mixture combustion products and gas exhaust stroke are carried out. EFFECT: increased efficiency of internal combustion engine, reduced consumption of fuel and pollution of ambient atmosphere when operating on non-leaned fuel-air mixtures. 2 cl, 1 dwg
