Abstract

A method of operating a two stroke engine comprises the steps of providing at least one cylinder; an intake system; an exhaust system; and a variable area valve; communicating between intake and exhaust systems; and varying the area of said valve to facilitate the variation of recoverable exhaust energy dependent upon the mode of operation of said engine.
