Title (EN) HIGH-SPEED SPECTROGRAPHIC SENSOR FOR INTERNAL COMBUSTION ENGINES
(FR) CAPTEUR SPECTROGRAPHIQUE À VITESSE ÉLEVÉE POUR MOTEURS À COMBUSTION INTERNE
Abstract: front page image
(EN)A high-speed absorption spectrographic system (10) employs a slit-less spectroscope (42, 71) to obtain high-resolution, high-speed spectrographic data of combustion gases in an internal combustion engine allowing precise measurement of gas parameters including temperature and species concentration.
(FR)L'invention concerne un système spectrographique d'absorption à vitesse élevée (10) qui emploie un spectroscope sans fente (42, 71) pour obtenir des données spectrographiques de haute résolution et à vitesse élevée de gaz de combustion dans un moteur à combustion interne permettant la mesure précise de paramètres de gaz comprenant la température et la concentration des espèces.
