Abstract: PURPOSE: An apparatus for measuring an amount of soot in diesel engine oil is provided to inspect a contamination degree of diesel engine oil by measuring intensity of light reflected from an interfacial surface between an optical rod and diesel engine oil in real time. CONSTITUTION: A soot measuring apparatus includes a sensor section(100) installed in a reservoir receiving diesel engine oil, a signal processing section for radiating light towards the sensor section(100) and for receiving light passing through the sensor section(100), and a light transferring section(120) for connecting the sensor section(100) to the signal processing section. The signal processing section has a light emitting part for radiating light towards the sensor section(100), a light receiving part for receiving light from the sensor section(100) and a display part. The sensor section(100) has a first supporter, a hollow housing(106), a second supporter(104) coupled to the hollow housing(106) and an optical rod(110).

Abstract: An apparatus for measuring soot content in diesel engine oil in real time comprises an optical rod capable of transmitting light and having a boundary surface adapted to be in contact with the diesel engine oil and first and second end portions, a light-emitting portion, and a first optical fiber connected to the light-emitting means. The first optical fiber is adapted to transmit light from the light-emitting means to the first end portion of the optical rod in an aperture angle of the optical fiber to the boundary surface. The apparatus also comprises a light-receiving portion adapted to receive light from the optical rod and output a signal corresponding to the received light power. The refractive index of the optical rod is larger than the refractive index of the diesel engine oil. The aperture angle of the optical fiber is equal to or larger than a critical angle reduced to air at which the light is totally reflected by the boundary surface.
