    A rotary combustion engine comprising a housing having an inner trochoidal surface and a rotor mounted within the housing and having apex portions having sealing cooperation with said trochoidal surface to form a plurality of working chambers therebetween and in which said trochoidal surface is modified at least in the region at the ends of its minor axis by displacing said surface outwardly in this region to avoid the usual crest in each of these regions and further in which the rotor periphery is modified so that it is substantially the inner envelope of this modified trochoidal surface.

    (54) ROTARY-PISTON ENGINE FOR INTERNAL COMBUSTION
    The invention relates to rotary pistons of internal traction engines with a trochoidal working chamber. Rotary-piston internal combustion engines are known, comprising a housing with a working chamber made in the form of a double-arc epitrochoid with small and large axes, and a rotor-piston mounted in a chamber rotatably rotatable. The contour of which is conjugated with the internal envelope of the prol of the working chamber, the profile of which measure for improving the working conditions of the sealing system is made with the correction of the epitrochoid on a periodic curve, the beginning of which coincides with one of the axes of the epitrochoid, and the period is a multiple of the period of the epitrochoid M. The disadvantage of these engines is a low compression ratio, which does not ensure its economic operation or the operation of the Diesel cycle. The purpose of the invention is to increase the degree of compression. This goal is achieved by the fact that the correction in the zone of the small axis of the epitrochoid is performed radially outward, and the profile of the periodic curve is formed by a cosine curve. FIG. 1 shows a rotary piston engine, cross section; in fig. 2 is a diagram of epitrochoid correction by imposing cosinusoids on it. In the housing (not shown) of the proposed engine, there is a working chamber, made in the form of a double-arc epitrochoid 1 (solid line) with a small 2 and a large 3 axis, and a rotor-piston 4 mounted in a rotatable chamber in the chamber, whose contour 5 corresponds to the internal envelope of the profile working chamber. The profile of the working chamber was corrected by imposing on the initial epitrochoid cosinusoid 6 (fkg. 2), the beginning of which coincides with one of the axes of the epitrochoid, and the period is a multiple of the period of the epitrochoid, and the correction is radially outward in the zone of the minor axis of the epitrochoid. The corrected profile of the working chamber is represented by the dash-dotted line 7 (Fig. 1), and the corrected rotor rotation profile - by the dash-dotted line 8. The invention allows a sharp increase in the compression ratio in internal combustion engines operating with external mixture formation, or to carry out the work of a rotary-piston engine on a cycle Diesel engine
    This invention, in addition to internal combustion engines, can also be applied in rotary-piston compressors with a trochoidal working chamber.
