MC Formula Validation Calculator

What is the MC Formula?

MC Formula is an SAE J2601 standard fueling protocol, available in the 2016 edition of SAE J2601. MC Formula calculates a dynamic pressure ramp rate using adaptive feedforward control based on the measurement of pressure and temperature at the dispenser in order to minimize the fueling time. The end of fill pressure target is also continuously and dynamically calculated throughout the fill.
