Design of an Optical Spectroscopy System for Combustion Measurement in Internal Combustion Engines

Measuring the scattered or emitted light from substances is widely used to detect and quantify chemical substances. Considering the internal combustion engines, ignition or combustion initiation is a key point in their operation. Many studies have been conducted to predict the ignition in engines. Among them, optical measurement techniques offer contactless and whole field detection of Ignition signs. Optical Spectroscopy is particularly in focus of researches as an effective tool to meet mentioned requirements. Spectroscopy option is needed as an effective tool. In this research, the design of a system with an optical sensor that can record the combustion process is presented. Fluorescent substances such as Kiton Red and Rhodamine are dissolved in the fuel and air mixture. Due to the design of the cylinder, part of which is made of quartz to be transparent and imageable, the light of the xenon lamp from One side is exposed to the solution.
