Abstract

Spectrophotometric methods provide many new possibilities of investigation of combustion process in the automotive engine with spark ignition. Emission spectrum of the flames from the combustion chamber provides valuable information, which is difficult or even not accessible with the aid of other measurement methods. Spectral analysis allows to evaluate concentration of active compounds present in flames, which do not constitute final products of combustion. Concentration of radicals depends on some combustion parameters such as air-fuel ratio. The paper describes an engine test stand equipped with fiber-optic measurement system. The measurement system consists of an optical sensor mounted in the engine head, fiber-optic bundle for signal transmission, grating monochromator and photodetector. Voltage signal from the photodetector is recorded by the PC- based data acquisition system. The main aim of research was to verify usability of the designed fiber-optic measurement system in combustion diagnosis and to develop a method of evaluation of the air-fuel ratio on the base of simplified spectral analysis of the emission during combustion process in an automotive gasoline engine.
