In this book, presented the development of a system for monitoring engine lubricants, temperature and vibration. The sensor can be integrated into the oil circuit of a engine in order to monitor the condition of the lubricating oil in use. The system works on the principle of non-dispersive infrared absorption measurement and uses a transmission setup consisting of two thin-film infrared emitters and two four-channel pyroelectric detectors. Seven different optical bandpass filters are used to monitor changes in the infrared absorption spectrum of the oil. To select the optical bandpass...

Dans cet ouvrage, nous avons présenté le développement d'un système de surveillance des lubrifiants, de la température et des vibrations des moteurs. Le capteur peut être intégré dans le circuit d'huile d'un moteur afin de surveiller l'état de l'huile lubrifiante en service. Le système fonctionne sur le principe de la mesure d'absorption infrarouge non dispersive et utilise une configuration de transmission composée de deux émetteurs infrarouges à couche mince et de deux détecteurs pyroélectriques à quatre canaux. Sept filtres passe-bande optiques différents sont utilisés...

Engine oil condition includes oil viscosity, oil cleanliness, air bubble content, and oil temperature. Being able to monitor these parameters will not only safeguard engine operation under an oil condition it was designed for, but will also provide a means to assess the health of the entire engine system since any deviation from the nominal state of these parameters could be linked to one or more faulty components.

In diesem Buch wird die Entwicklung eines Systems zur Überwachung von Motorschmierstoffen, Temperatur und Vibration vorgestellt. Der Sensor kann in den Ölkreislauf eines Motors integriert werden, um den Zustand des Schmieröls im Einsatz zu überwachen. Das System arbeitet nach dem Prinzip der nicht-dispersiven Infrarot-Absorptionsmessung und verwendet einen Transmissionsaufbau, der aus zwei Dünnfilm-Infrarotstrahlern und zwei vierkanaligen pyroelektrischen Detektoren besteht. Sieben verschiedene optische Bandpassfilter werden verwendet, um Veränderungen im Infrarotabsorptionsspektrum des...

The reason behind this that when a driver is driving a vehicle, the area around the vehicle is cannot be directly observed the driver. There are some cases that when another vehicle approaching an overtake, the blind spot in the rear-view mirror cannot detect the vehicle and these blind spots are the source of multiple accidents. In order to reduce the side collision in heavy vehicles we have come up with the solution called Blind spot Detection. This system will be working on the principle of ultrasonic making the driver alert by the technology of haptic- touch. This kind of Haptic-touch...
