Mass moment of inertia for a particle: The mass moment of inertia is one measure of the distribution of the mass of an object relative to a given axis. where O-O is the axis around which one is evaluating the mass moment of inertia, and r is the perpendicular distance between the mass and the axis O-O.
Differential Pressure DP Sensor The differential pressure sensor is used for flowmeasurement of the Diesel Particulate Filter (DPF). Thissensor has two pressure ports and senses the differencein pressure between the two ports.
When the fuel mixture is rich (less oxygen in the exhaust), the sensorâs output jumps up to a high of about 0.9 volts. The high or low voltage signal tells the PCM the fuel mixture is rich or lean. On some newer vehicles, a new type of âwidebandâ oxygen sensor is used.
