NORMAS INTERNAL COMBUSTION ENGINE, VERSION - NORMAS N 26 Russian patent published in 2019 - IPC F02B41/02 

FIELD: machine building.

SUBSTANCE: invention relates to the engine building. Crankless two-stroke internal combustion engine (ICE) includes a modular composition of a prefabricated housing, synchronization assemblies and three units, identical in composition and size ratio of single-type groups of modules so that movable elements of these modules synchronously interact with each other. At that, paired groups of modules are located and fixed in different parallel planes, and between them there are built-in gears identical in the set of gears and performed function - mentioned above units of rotation synchronization of shafts and power takeoff of internal combustion engine. In the combining synchronizing module, the power take-off function is carried out by a gear (epicycle) with two rims of internal engagement teeth. Rotation and power takeoff synchronization modules are arranged between other modules to rotate in rolling bearings and to be locked from coaxial movements in thrust bearings. In each paired module between two cylindrical cylinders there is a semi-cylindrical shape half-cylinder rocker, which is made with formation of two guide trays, between which there is a hemispherical-shape slider. One nozzle is arranged in the bushings of the cylinders. Gas duct profiles are assembled from the branch parts, and a plate-like partition is mounted inside the bend. Paired modules are equipped with an air pump with a cylinder cup-type seal and two different air-distributing units complete with a tank, where the balloon-type membrane is located.

EFFECT: technical result consists in improvement of engine torque.
