Design and Development of Oil Mist Detection Module for Marine Engine

Oil mist detector is an important equipment in the early stage of the explosion of the crankcase for marine engine, and the oil mist detection module determines the working performance of the oil mist detector. By means of infrared light transmission principle, method and compositions of the detection module was extracted. Through analyzing the safety and reliability of hardware circuit module, real-time and accuracy of detector, overall scheme design of oil mist detection module was carried out. By analysis of principle and detection method oil mist, power and photoelectric conversion modules were designed and developed. Finally, laboratory verification of oil mist detection module was conducted, experimental results showed the module satisfied the design and function requirements.
