  • Patent number: 8707773
    Abstract: A method of monitoring oil in a vehicle having an internal combustion engine is provided. The method includes setting an original oil life, which is measured by event units occurring in the engine, and measuring a lapse of the event units. The method calculates a remaining oil life as a function of the lapse of event units and the original oil life. The remaining oil life is expressed in terms of the event units. The method monitors for oil additions and calculates an addition credit from any monitored oil additions. The method also includes calculating a modified oil life as a function of the addition credit, wherein the modified oil life is expressed in terms of the event units.

  • Patent number: 8482420
    Abstract: A method of monitoring oil in a vehicle having an internal combustion engine is provided. The method includes measuring a sump temperature of the engine and measuring a power output of the engine. Oil consumption is calculated as a function of the measured sump temperature and the measured power output. Remaining oil life is calculated as a function of the calculated consumption. The method may include alerting a receiver of the calculated remaining oil life.

  • Patent number: 8359913
    Abstract: A method is provided for determining remaining oil life prior to an oil change in an internal combustion engine that uses a body of oil. The method includes transferring the body of oil to the engine and determining a volume of the transferred body of oil. The method also includes determining whether an oil squirter is present in the engine. Additionally, the method includes determining the remaining oil life based on the determined volume of the body of oil and whether an oil squirter is present in the engine. Moreover, the method includes activating an oil change indicator when the remaining oil life reaches a predetermined level. A system for determining a number of engine revolutions permitted on a volume of oil is also disclosed.

  • Patent number: 5185773
    Abstract: An amount and distribution of platinum dispersed on a catalyst carrier is determined by generating at least two energy components of lead x-rays by fluorescence of lead with gadolinium or cobalt and directing the x-rays onto a surface of the carrier and then determining an amount of platinum based upon relative attenuation of the two energy components of lead x-rays proportional to a relative amount of platinum thereon.
