  2. Oxygen sensor - Wikipedia

    en.wikipedia.org/wiki/Oxygen_sensor

    Using the O2 sensor signal, the ECU can operate the engine with an air–fuel ratio very close to 14.7:1, which is the ideal operating mixture for a three way catalyst to be effective. [3] Robert Bosch GmbH introduced the first automotive lambda sensor in 1976, [ 2 ] and it was first used by Volvo and Saab in that year.

  3. Electro-galvanic oxygen sensor - Wikipedia

    en.wikipedia.org/wiki/Electro-galvanic_oxygen_sensor

    Pre-dive calibration of the cells can only check response to partial pressures up to 100% at atmospheric pressure, or 1 bar. As the set points are commonly in the range of 1.2 to 1.6 bar, [6] special hyperbaric calibration equipment would be required to reliably test the response at the set-points. This equipment is available, but is expensive ...

  5. VO2 max - Wikipedia

    en.wikipedia.org/wiki/VO2_max

    V̇O 2 max (also maximal oxygen consumption, maximal oxygen uptake or maximal aerobic capacity) is the maximum rate of oxygen consumption attainable during physical exertion. [1] [2] The name is derived from three abbreviations: "V̇" for volume (the dot over the V indicates "per unit of time" in Newton's notation), "O 2" for oxygen, and "max" for maximum and usually normalized per kilogram of ...

  6. Thermal velocity - Wikipedia

    en.wikipedia.org/wiki/Thermal_velocity

    Thermal velocity or thermal speed is a typical velocity of the thermal motion of particles that make up a gas, liquid, etc. Thus, indirectly, thermal velocity is a measure of temperature. Technically speaking, it is a measure of the width of the peak in the Maxwell–Boltzmann particle velocity distribution

    Critical ionization velocity experiment onboard space shuttle Discovery (), releasing a plume of nitrous oxide gas. Full text. Critical ionization velocity (CIV), or critical velocity (CV), is the relative velocity between a neutral gas and plasma (an ionized gas), at which the neutral gas will start to ionize.
