Title
(EN) A method of identifying engine gas composition
(ZH) 识别发动机气体组成的方法
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.
