Title
(EN) A METHOD OF IDENTIFYING ENGINE GAS COMPOSITION
(FR) PROCEDE D’IDENTIFICATION DE COMPOSITION DE GAZ DE MOTEUR
Abstract
(EN)
A method and apparatus of identifying engine gas composition in an engine cylinder comprise obtaining a measure of cylinder pressure from a cylinder pressure sensor, deriving the polytropic index from said measure and obtaining a measure of the quantity of an engine gas component therefrom.
(FR)
La présente invention concerne un procédé et un appareil d’identification de composition de gaz de moteur dans un cylindre de moteur qui comprennent les étapes consistant à obtenir une mesure de pression de cylindre à partir d’un capteur de pression de cylindre, dériver l’indice polytropique à partir de ladite mesure et obtenir une mesure de la quantité d’un composant gazeux de moteur à partir de ceux-ci.
