TWO-STROKE ENGINE OF INTERNAL HEATING OF WORKING MEDIUM Russian patent published in 2012 - IPC F02G1/02 F01B15/04 F01B23/10 

FIELD: engines and pumps.

SUBSTANCE: two-stroke engine of internal heating of working medium includes casing, cylinders with finning and two support axes directed perpendicular to rotation axis of cylinder, lower cover plates of cylinders, pistons with outlet valves, which are located at their bottoms, stocks, detachable crankshaft, rolling bearings, valves, blade-type fan and a flywheel. Crankshaft has a flywheel. Stocks that are introduced to volumes of cylinders through central holes of lower cover plates of cylinders and connected to the pistons dividing the cylinders into working and auxiliary cavities are attached to bellcranks. There are outlet valves on front surface of pistons. Cylinders are fixed by means of support axes through bearings in the casing. Transverse slots that are covered with valve plates forming the inlet valves are made in cylinders opposite outlet valves located in pistons. Intake pipes taken out of the casing are installed in cylinders on the casing at the points opposite the location points of transverse slots. Free end of crankshaft is connected through pulleys by means of belt transmission to blade-type fan feeding the air to the casing volume through filtering panel. Engine has top cover plates of cylinders, in which there made on end working surface are channels connected to each other and representing a parable in cross section, heat-insulating casings, which are fixed on external surface of top cover plates of cylinders, electric heating elements, sliding current collectors, hold-down current conductors, crankshaft position sensor, electronic control unit of load current interruption, accumulators, electric current generator and leads. Forming the working cavities, upper ends faces of cylinders are closed with top cover plates of cylinders. Auxiliary cavities of cylinders are filled with oil to the level when it is touched with skirts of pistons. Electric heating elements are fixed in channels of cover plates of cylinders; at that, two connecting ends of electric chain of the above elements are connected to two outward projecting sliding current collectors fixed on each cover plate of cylinder. Hold-down current conductors are fixed on the casing, directed and bent along the radius of the rolling trajectory of sliding current collectors and have contact to them, and are connected to the buses taken out to the outer side of the casing. Buses of hold-down current conductors are connected by means of leads to accumulator through electronic control unit of load current interruption, which has wire communication to position sensor of crankshaft, which is installed on the casing. Electric current generator is connected through mechanical transmission to crankshaft. Through-type channels the inlets of which are shutoff with inlet valves installed on the casing and on end face of free end of crankshaft are made in casing body, in crankshaft body and in stock body for periodic oil lubrication of bearings.

EFFECT: heating of working medium of the engine by means of electric heating element.
