INDUCTION-EXHAUST SYSTEM FOR A ROTARY ENGINE

摘要

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.
