Event
Prognostics is an engineering discipline focused on predicting the time at which a system or a component will no longer perform its intended function. What is the value of predicting failure? How do you select the right information to create an algorithm? How do you test an algorithm to make sure you are predicting failures properly? This session will explore new algorithms to catch anomalies on various automotive systems. Catching the failure before it happens is the key. Meet the experts.

Soot emission from internal combustion engines is strictly regulated and upcoming requirements present a challenge. Laser extinction measurement (LEM) and natural luminosity of sooty flames have been used to analyze soot formation and oxidation processes. LEM measures soot along the laser beam path and it can probe soot regardless of temperature. Natural luminosity measurement is a global measurement and highly relies on soot temperature. In this work, a comparison of simultaneously recorded LEM and natural luminosity data has been performed in a heavy-duty optical engine. A 685 nm laser beam is used for LEM to minimize the absorption by fuel or PAH. The laser was modulated at 63 kHz, which facilitated subtraction of the background natural luminosity signal from the raw LEM data. Temporal offset is found between the LEM and natural luminosity data. The LEM detects ‘soot’ earlier than natural luminosity measurement.
