For the calculation of the corrected hot consumption of the vehicle fleet, the equation for the basic hot emissions has to be<br />
converted to:<br />

Effectively, the product n i .l i in the above equation corresponds to “vehiclekilometre” (number of vehicles by travel distance) for<br />
each vehicle category i.<br />
For gasoline (with and without catalyst) and diesel cars (without catalyst), the formula for excess consumption) is in the following<br />
form:<br />
excess consumption= w×[f(V)+g(T)1]×h(d)<br />
d = d / d c<br />
engine start temperature (in °C) for starts at an intermediate temperature<br />
It is assumed that the excess emission of diesel cars with oxidation catalyst is proportional to the excess emission of diesel cars<br />
without catalyst, according to the following equation:<br />
