Load


 * Engine load: Also known as relative cylinder charge. It represents the percentage of air (compared to standard density) in each of the cylinders. 100% load means each cylinder has the mass of air as an equivalent volume at standard density. Injested air mass is calculated from MAF value (mass/time) divided by RPM (1/time) to yield a mass. Standard mass is calculated by engine displacement (volume) divided by standard density (mass/volume). The ratio of the two is load. It is used in real time to control all other values including boost and fueling.


 * Engine load specified: The maximum target load based on programmed values; generally depends only on RPM.


 * Engine load corrected specified: Adjusted maximum target load based upon a number of internal and external values, two externals being ambient temperature and pressure. Internals are usually due to engine wear trims.


 * Requested load: Target load based on the accelerator pedal position. It is capped by engine load corrected specified and will never exceed that value.
