The invention relates to engine building, and specifically to reciprocating internal combuston engines. The technical result of the invention consists in simplifying the design, the possibility of monitoring and regulating the moment of self-ignition of a homogenized fuel-air mix, and reducing the specific flow rate of the fuel. The method for operating an internal combustion engine consists in feeding a charge to the combustion chamber of a main cylinder and an auxiliary cylinder which are connected to one another and have different diameters, and in which the pistons are arranged. The piston of the auxiliary cylinder is delayed in accordance with the shaft rotation phase with respect to the piston of the main cylinder and as the piston of the main cylinder reaches the upper dead center thereof, when the majority of the charge is located in the auxiliary cylinder, and the charge to the piston of the auxiliary cylinder is boosted. The piston of the main cylinder is used to compress the mix without bringing said mix to self-ignition and therefore preparing said mix for subsequent rapid ignition, while the piston of the auxiliary cylinder is used to boost the compressed homogenized fuel-air mix, and said mix is brought to the temperature and pressure in the combustion chamber prior to compression self-ignition of the mix.
A method for operating an internal combustion engine, comprising the feeding of a charge to the combustion chambers of the main and auxiliary cylinders, joined together and having different diameters, in which pistons are located, compression of the change by the pistons in both cylinders, while the piston of the auxiliary cylinder is delayed in shaft rotation phase from the piston of the main cylinder, and after the piston of the main cylinder reaches its upper dead center, the charge is boosted by the piston of the auxiliary cylinder, characterized in that a homogenized fuel and air mix is fed to the cylinders and compressed by the two pistons, while the piston of the main cylinder compresses the mix without allowing it to self-ignite and thus preparing it for the subsequent rapid ignition, while the piston of the auxiliary cylinder boosts the compressed homogenized fuel and air mix, bringing its temperature and pressure in the combustion chamber up to a compression self-ignition of the mixture.
