INTERNAL COMBUSTION ENGINE "NORMAS" NO. 48 OF A SCARABEY MINI-TRACTOR Russian patent published in 2022 - IPC F02B41/02 F02B73/00 F01B21/02 

FIELD: engine building.

SUBSTANCE: two-stroke internal combustion engine includes body assemblies (32), also configured to ensure the kinematic interaction of modules (01), (03) with the working stroke as well as configured for operation thereof on fuel of kerosene-gas oil fractions, by introducing one of the variants of the synchronisation module, and modules (02) and (04) operating in the mode of continued exhaust gas expansion, wherein said modules can be also configured to afterburn the hazardous components from still-hot exhaust gases from modules (01), (02), or to be transferred to the mode of operation of modules with a working stroke, wherefor the prefabricated covers (14) of the cylinders (18) are equipped with unified sockets (26*) for nozzles; wherein the mounted bellows (15) with pneumatic cylinder elements and control springs (22) and various branch pipes (19), (20) are capable of forming the air system of the ICE and the cavities of the two-chamber tyres (25) with the necessary volumes by drilling two grooves in the body of the shaft (00), as well as causing the extension of the two sockets (26) secured on the bellows (15*) for the cutters of the grousers over the dimensions of the tyres (25) of the wheels of the Scarabey mini-tractor.

EFFECT: increased torque of the engine.
