Research of Portable Vehicle Oil Performance Detector
In order to address the limitations of single parameter evaluation of engine oil performance, a portable vehicle oil performance detector is designed, realizing comprehensive on-line detection of oil rapidly, easily, and accurately. The detector takes oil performance as study object and proposes an on-line measuring method of oil performance through detection of oil viscosity, dielectric constant and temperature. Data and information collected by transmitter are sent to PIC single-chip microcomputer through RS485 communication module. Measured values are displayed on the LCD by SCM receiving the key signals. Test results show that, the detector works stably and is easy to use with small error, and is able to further determine the extant of oil contamination through a comprehensive analysis of the three measuring parameters. To a certain extant, it promotes the rational use of oil.
