Patent attributes
An engine comprises a working cylinder provided with a piston, a preignition chamber provided with a spark plug and a combustion chamber which are connected to a compressor cylinder by channels. The compressor cylinder is provided with fuel and air supplying channels arranged in the top section thereof and with a piston and a shutoff valve. Return valves are mounted at the output of the valve supplying air to the compressor cylinder. The corresponding method for operating the engine consists in adjusting the velocity of a fuel-air mixture injection into the preignition chamber and the combustion chamber by modifying pressure in the compressor cylinder. When the fuel-supply impulse is increased, the pressure is also increased and vice-versa, when the impulse is reduced, the pressure is also lowered, thereby ensuring an air/fuel ratio in the preignition chamber equal to 8:1-20:1.
