Abstract

The present invention relates to a method of measuring the quality of vehicle oil by optical spectroscopy. This method consists of exposing a sample of engine oil from a vehicle to two LEDs which alternately transmit beams of light. The light is detected by a sensor and converted into electrical pulses with an amplitude proportional to the intensity of the light detected. These electrical impulses are converted into a digital signal which is used by the processor to convert it into a ratio representing the quantity of CO2 and impurities in the oil.
