Wilmers, G

Improvements are described for a rotary internal combustion engine of trochoidal type, having a housing comprising at least one peripheral shell with a multilobed inner peripheral surface and at least two parallel side walls with the shell disposed between the side walls. The housing defines an engine cavity within which a rotor sweeps the inner surface, sealing an intake port for supplying fresh gas. The improvements are: (1) the side wall has an induction channel connected to the intake port; (2) a rotary valve is adjacent to the intake port; and (3) the valve cooperates with the upstream edge of the port to form a throttling gap which progressively increases the cross-section of the open area of the port as the valve turns in the opening direction and progressively delays the closing time of the port with increasing valve opening.
