<p>Disclosed herein is a rotary internal combustion engine comprising a generally trochoid shaped housing including a pair of spaced generally parallel side walls, a generally triangularly shaped rotor supported within the housing for rotation about an axis perpendicular to the side walls, which rotor includes three generally identically shaped side flanks which define, in cooperation with the housing, respective chambers which rotate with the flanks and which vary in volume in accordance with such rotation. The side flanks each include an end which leads in relation to the direction of rotor rotation, an end which trails in relation to the direction of rotor rotation, and a length extending between the leading and trailing ends. In addition, one of the side walls includes a charge inlet port which selectively communicates with the chambers in response to rotor rotation, which extends arcuately relative to the rotor axis, and which includes a portion which terminally communicates with the chambers and which is located such that the portion is closed off from communication with the chambers by respective parts of the flanks, which parts are spaced from the trailing ends in the direction toward the leading ends at a distance of from about 35 to 70 percent of the flank length.</p> |
