Operation of two-cycle engine

Abstract

Abstract PURPOSE: To make it possible to operate an engine at a low compression ratio, by chemically activating a part of mixture by heat. CONSTITUTION: When a piston 13 moves down and a scavenging port 24 is opened, a mixture flows from a chamber A of a resonator 30 and a conduit 28 into a cylinder 12 and the pressure in the chamber A falls rapidly. At the same time, the chambers A, B, C of the resonator 30 become unbalanced to one another and a spring 36 for the chamber A is compressed by springs 37, 38 for the chambers B, C to accelerate the introduction of the mixture into the cylinder 12. Thereby, a laminar mixture supply is effected well without disturbing the residual gas in the cylinder 12 and a combustion chamber 16. Therefore, a part of gasoline of the mixture is decomposed and activated by the heat of the residual gas and the adiabatic compression heat so that radicals of chemically high acftivity are produced. This makes it possible to burn the mixture at a low compression ratio COPYRIGHT: (C)1979,JPO&Japio
