Abstract
An induction and exhaust system for a rotary engine is disclosed which has a wing-type reed valve assembly disposed in the intake port of said system and effective to respond instantaneously to a back-flow differential pressure for closing the intake port; the assembly is capable of cycling at least 120 times/second. The system substantially eliminates various types of dilution and variance of the inducted mixture enabling a high velocity peripherally ported engine to deliver an improved low end engine torque characteristic and improved overall fuel economy for a passenger automotive vehicle. Various types of wing reed valve constructions are illustrated, the preferred mode having 16 reed valves arranged with the trailing edge of the assembly cage aligned with the exit of the intake port; the center line of the intake port is located substantially at theoretical zero pressure difference between the adjacent chambers defined by the rotor and housing. A multiple-staged carburetor increases road load induction velocities and the induction air fuel mixture is heated by the exhaust system in a controllable manner through the use of a modulating flapper valve disposed in a heat transfer section.
