Abstract
The problem of reducing CO2 emissions is one of the main problems of the automotive industry, in which all the largest manufacturers are investing a lot of funds in order to comply with the limitations of the legislators. Nowadays, the main solutions adopted go in the direction of increasing electrification of vehicles, with the creation of hybrid and electric vehicles.
In this work will be described the architecture of a powertrain that can be classified as Mild-Hybrid, going into detail of its components and explaining peculiarities and operating strategies.
It will then follow the study of the regulations that characterize and regulate the approval of hybrid vehicles with no external charge, from the point of view of emissions of pollutants and carbon dioxide.
Finally, an analysis of the data collected on the homologation cycles of the hybrid car has been done, in order to determine the applicability of the correction coefficient KCO2, based on the cancellation of the energy balance of the batteries, and the procedure for its calculation.
